Abstract
ABSTRACT
Apparatus is disclosed which is suitable for deshirring and smoothing a shirred tubular casing as the casing is being stuffed. The tubular casing has an interior surface of predetermined internal diameter when unshirred.
The apparatus includes a hollow body of generally annular configuration having a circumferential wall of generally circular cross-section which defines a closed external surface having a diameter which increases from a first end to a maximum at a second end of the hollow body. The hollow body has a central opening for receiving a stuffing tube and an external surface of the stuffing tube is releasably engaged to mount the hollow body on the stuffing tube. The hollow body is constructed of a rigid material, and the maximum diameter of said external surface is smaller than the predetermined internal diameter of the unshirred tubular casing. When the hollow body is arranged within a de-shirred section of the tubular casing, the tubular casing and the hollow body are mounted on the external surface of the stuffing tube, and the casing is stuffed with a mixture from the stuffing tube, the interior surface of the tubular casing slides over the generally circular external surface of the hollow body and is thereby deshirred and smoothed.

~ackground of the Invention 1. Field of the Invention ~ he invention relates to a device for use with stuffing machines for stuffing shirred tubular casings having a uniform dia~eter. I~ particularly relates to a device which is adapted for mounting on the stuffing horn of such machines for effectins deshirring and smoothing oE the shirred tubular casing prior to stufring.
2. The Prior Art It is known to use shirred tubular casings of a synthetic, semi-synthetlc or natural material for the packaging of food items such as, for example, meat, in the orm o~ sausages. The shirr~d casings ulilized for this purpose, also called "sticks" or !'hollow rods" by those skilled in the art, ara produced b~ shirring and compressing long tubes oF casing in the direction of their longitudiral axis to approximately one to three percent of their orlginal length In 2G order to fill the shirred casiny with sausage compo-sitiorl or other food product, conventionally one end of the shirred casing is first closed, and th~n the shirred casing is normally fit onto the stufLing tube of a stufring machine. A sausage ~,ix~ure is then forced, ~nder pressure, through the stuffing tube into the cacing, ~y which the shirred casing is continuously deshirred. After a predeter~ined lenyth o~ the cas-ng has heen filled, the filled sausage casir.g is su~-divided into cylindrical sausages which are then tied o~f and closed~
Por a number of reasons, it is desirable that the diameter of the sausages thus produced remains constant over their entire length. Optimum filling of the tubular casing requires that a uni~orm diameter, khe size of which is dependent upon the particular - casing, be maintained over the entire length of the casing. If the casing is overstuffed, it may burst, while an insufficiently filled sausage will have a wrinkled surface.
Several prior art devices have been developed for uniformly controlling the diameter of the tubular casing during fi]liny with sausage mixtures or other food products. Thus, it is known to fit a calibrating means to the opening of the stuffing horn, which pre-stretches the casing to be filled by pressing against the inside wall thereof. The contact pressure creates frictional forces between the calibrating device and the inner wall of the casing, which acts to slow down withdrawal of the casing from the stuf~ing horn (U.S.
Patent NQ. 3,457,588). Suitable calibrating means which have heretofore been used in the prior art comprise, for example, resilient fingers disposed at the rim of the stuffing horn opening, which are produced by forming slits th~rein ~U.S. Patent No. 3,264,679).
These fingers press against the internal wall of the casing and thus enlarge it. By drawiny khe casing over these fingers during the stuffiny process, a frictional resistance is created whlch controls the draw-off speed of the casing fro~ the stuffing horn.
This device has the disadvantage, however, that the frictional resistance is very high during the stuffing process, and the casiny may thus tear. Furthermore, there is the danger of damage to the casing by the spread fingers. Moreover t the device does not repre~
sent an independent functional unit comprising a calibrating member and a tubular casing.
` ( ( ~ ( (~
It has also been proposed to prep~ckage the shirred tub~lar casing together with a cali-brating disk and to attach this combination to the stuffing horn prior to the filling operation (U.S.
Patent No. 4,007,761). The calibrating disk is disposed within an unshirred section of the casing and has an external circumference which must be larger than the internal circumference of the unshirred casing. During filling, the casing is drawn over the calibrating disk and is thereby stretched.
The calibrating disk must therefore be made of a rigid, inelastic material in order to prevent its diameter from being altered by the pressure of the casing against the circumference of the calibrating disk.
This inelastic calibrating disk therefore has the disadvantage that in the case of fluctuations in the circumference of the casing - which cannot be entirely avoided during manufacture - an optimum filling of the casing is not achieved. When the internal diameter of the casing is too small, there is also the danger that it will be damaged or torn by the calibrating disk. At the very least, an undesirably high friction will occur between the casing and the calibrating disk, leading to overstuffing of the casing with sausage mixture and the inability to withstand the high pressures formed during boiling of the sausage.
A calibrating device is further known (U.S.
Patent No. 4,202,075) which is made of a flexible material and which has a variable diameterO This device is also intended to stretch and expand the tubular casing prior to its being filled with a sausage compo-sition, while the device provides a controllable degree of expansion. Even with this device, however, strong frictional forcec between the tubular casing and the calibrating device can occur.
' c~
Other prior art casing calibrating devices and stuffing arranyements are shown, for example, in U.S. Patent Nos. 4,077,090, 4,017,941, and 4,034,441. Each of these arrangements employs a sizing disk having an external diameter somewhat larger than the internal diameter of the deshirred casing.
Summary of the Invention It is an object of the present invention to provide a device suitable for deshirring and smoothing a shirred tubular casing prior to its entry into a brake part of a stuffing installation, wherein the tubular casing is converted from its shirred state to a satisfactory creaseless condition without exposing the tubular casing to the danger of being damaged. The device of the present invention is intended to make possible the drawing of the tubular casing into the brake part of the stuffing installation in a defined manner, free of jerking movements thereby reducing 2Q the danger that the tubular casing might be torn.
In contrast to the prior art calibrating disks which have an external diameter larger than the internal diameter of the tubular casing, the present invention provides an annulax hollow body haviny a maxlmum externaL diameter which i5 smaller than the internal diameter of the deshirred tubular casing;
this relationship had not been predictable because it has heretofore been the generally-accepted opinion of those skilled in the art that the spreading and expansion of the tubular casing is necessary. Contrary to the prior belief that spreading and expansion of the tubular casing is always necessary, it has now been found not only that expansion is not required for the satisfactory stuffing of the tubular casing, but that it is actually a disadvantage. It is entirely adequate to draw the tubular casing, for the purpose of 5~ ~
deshirring and smoothing, ovcr the externa:L surEace of the ~lnnular hollcw bod~, wlthout e~panding -the tubular casing beyond its original diameter. m e maxinum diameter of the annular hollcw bcdy is 70 percent to 99 percenk, preferably 90 percent to 99 percent, of the internal diameter oE the unshirred tubular casing.
The tubular casing consists, for example, of material c~st~marily used in the production of sausages, such as cellulose hydrate, collagen or synthetic intestines and maybe Eiber reinforced. The casing has the usual coatings on its inner and/or outer surfaces, e.g., of a material impermeable to water vapor and oxygen. When a cellulose hydrate casing is used, it may have the usual water con-tent of, for example, 6 to 10 percent, but also may have a very high water con-tent of, for example, up to appro~imately 35 percen-t, so that there is no need to soak it in water prior to stuffing~
The essential portion of the device according to the invention is the annular hollcw body which acts to deshirr and smooth the tubular casing prior to its stuffing with the sausage mixture. It consists of a circular ring with a central orifice for the applica-tion and fixation on the stuffing tube of a stuff-ing de~ice, such as is customarily used for the stuEfing oE sausage mixtures in-to tubulæ casings. me hollow body is mounted on the stuffing tube, for example, by means of threads or a bayonet lock, preferably by means oE a spring lock arrangement in the form oE at least two resilient webs or a Seeger ring (an expandcible securing ring) adjacent to the c~ntral orifice of the hollow bcdy, which engage a grooved recess in th~ outer surface of the stuffing tube. The hollcw body is relatively inelastic and rigid and preferably consists of a metal or a synthetic material such as polyprcpylene or polyethylene. When a synthetic material with a modulus of elasticity of 10 -10 N/mm is used, ,~
t~
a thickness of, for example, two to six mill~neters is adequate to obtain a sufficiently rigid hollow body. The elastic spring webs then must be of a relatively small thickness of approximakely two to three millimeters.
The external surface of the annular hollow body preferably has the shape of a conically expanding annular surface which expands in a direction opposite to that of the shirred casing. The tubular casing is then drawn with its deshirred part over the annular surface.
This arrangement insures that the tubular casing, prior to stuffing and during the deshirring, attains an internal diameter amounting in the deshirred state to 70 percent to 99 percent, in particular 90 percent to 99 percent, of the internal diameter of the tubular casing prior to shirring. Any expansion or spreading of the casing is thus eliminated, together with its detrimental effect on the filling process.
~ The leading end of the portion of the tubular casing deshirred by passage over the hollow body is drawn through an annular brake prior to stuffing, the annular brake serving to narrow the diameter of the casing and exer1 a compression and braking force;
dunng stuffing the casing is drawn through an installa-tion, such as a clip device, which closes or binds the casing at periodic intervals, and then through a cutting station to form individual sausages.
Due to the pressure with which the paste-like stuffing material, such as a sausage mixture, is pressed through the filler tube into the deshirred portion of the tubular casing, the casing slides continuously over the external surface of the annular hollow body, causing the casing to be deshirred ana smoothed without generating substantial frictional forces as a result of the mutual contact. A drawing velocity of 10 to 20 meters per minute is customarily used. The length of the external surface of the annular hollow body is advantageously 2 to 4 cm., so that at such a drawing velocity the maximum contact time between the external surface of the hollcw body and the interior surface of ~he tubular casing is usually about 0.2 sec. The shirred part of the casing is held back by the annular hollGw bcdy. This insures additionally that only deshirred and smoothed portions of the casing may entex the brake unit and thus that the danger oE breaking o-E the cas-ing is clearly reduced.
Following ~he complete filling of the casing, the calibrating part (i.e., annular hollow body) is removed frcm the stuffing tube and may be reused.
A shirred tubular casing with an exterior pr~tective covering may be provided as a pre-assembled functional unit. The protective covering consists in particular of a heat-sealable thermoplastic synthetic material such as polyamide, polyvinylchloride or a polyolefin, which may have latent shrinkability actuated by heat. It forms a supporting container for the shirred casing arranged within its cavity.
In a preferred embodiment, annular disks are provided at the respective ends of the shirred tubular casing, with the protecti~e covering extending through the central circular oE~ening of the disks and being turned back around the external circumference of the disks in the direction of the center oE the pro tective covering, as sho~l in Figure 4 of West rær~an Application ~E-OS 25 10 637 (corresponding United States Patent No. 9,013,099). The turned-back portion of the protective covering is preferably heat-sealed to the external surface of the protective covering in contact with the tubular casing.
m e protective covering is a tubular film, preferably with perforations or r.et-like or lattice-like structure.
In the case of protective coverings of shrinkable film, the shrinkage is ef~ected in the area of the portion turned back around the annular disk.
;`'`~.1 L
The deshirred portlon of the tubular casiny extendiny over the external surface of the annular hollow body is located outside the protective cover, and cne of the annulæ disks is directly adjacent to one end of the hollow bcdy.
~hen the ~hus pre assembled functional unit is to be filled, the shirred tubular casing is pushed with its open end cnto the stuffing tube of thestuffing machine and the hollow bcdy is secured to the external surface of the stuffing tube by means of the locking mem~ers provided on its internal circ~Imfer-ence, for ex~ ple, the resilient web-like elements or the Seeger ring ~an expand-able securing ring). A paste~like mass, such as a sausage mixture~ is pressed out of the stuffing tube into the tubuk~r casing, while the tubular casing slides through the central circular opening of the annular disk and subsequently over the circumferential outer surface of the hollcw body, whereby the tubular casingis deshirred and sm~othed. The diamPter of the central d rcular opening of the annular disk must be suitably large; advantageo~sly, it is at least as large as the inte mal diameter of the shirred tubulæ casing.

escription of the Preferred Emtodiments As shown in Figures 1-3, an annular hollow body 1 has an external dia-meter which increases - from a first end 2 -to a second end 3 - -to a m~ximum value. The annular hollow bcdy thus has a closed external circumferential sur-faoe 4. The internal circumference of the hollow body is provided with three ~eb-like ele~.ents 5 which have a resilien-t spring action and which have curvededges 6 lying in planes parallel to the longitudinal axis of the hollcw body 1.
Figure 3A sh~s a modified form of the hollow body of Figures 1-3.
Viewed in front elevation, the mLdified hollow body of Figure 3A appears the same as shcwn in Figure 1. However, when viewed in the sectional side elevation view of Figure 3A, it can be seen that each web-like element 5' has only a single curved edge 6'. Except for this difference, the modified hollow body 1' of Figure 3A is identical to the hollow body 1 of Figures 1-3.
Figures 4 and 5 shcw a further embodiment of the annular hollow body 1~
having a Seeger ring (an expandable securing ring) 7 rather than the web-like ele-ments. The Seeger ring 7 is joined to two steps 8 and to the internal circumfer-ence of the hollcw body 1 at a base area 9. Beveled inner edges 10 enyage grooves 12 of a stuffing tube 11 (Fiyure 6); recesses 17 of the Seeyer ring 7 are necessary for the passage over bosses 14 of the stuff:ing tube 11.
In E'igures 6, 7 and 8 the annular hollow body 1 of Figure 1 ls shcwn pushed onto a stufE.ing tube 11, with each of its web-like elements 5 en~aging recesses or grooves 12 in the stuffing tube 11. In order to remove hollow bcdy 1from the stufflng tube 11, the annular hollcw body 1 is rotated in the directionof the arrow 13 (Figure 6), whereby the web-like elements 5 are resiliently biased onto the bosses 14 of the stuffing tube 11 (Figure 7), so that the annular hollow .~
body 1 may be pulled off the stufflng tube 11. With hollow bocly l removed, a shirred tubular casing 15 (Figure 8) may be mounted on the stuffing tube 11;
the tubular casing slides over the external surface 4 of the remounted annular hollow body l, whereby it is deshirred and smoothed.
Figure 9 shows in sectional side elevation view an arrangement in which a paste-like sausage mixture 16 is forced into the tubular casing 15 from a stuffing tube ll. The casing ~5 is in the shirred state on the stuffing tube ll; it slides over the annular hollow body l and through a brake element 18, and then passes through a schematically-represented cutting station l9 and tying station 20. Arrangements of this type are described, for example, in U.S.
Patent Nos. 4,017,941 and 4,077,090.
In Figure lO, a pre-assembled functional casing unit is represented; which comprises the shirred tubular casing 15 with a deshirred end portion thereof drawn over the hollow body l and closed off. A
protective covering 21 surrounds tile shirred tubular casing 15 and passes around annular disks 22. It ls turned back to the middle of the tubular casing and joined by means of heat sealing with the part of the protective covering surrounding the shirred tubular casing 15. In order to fill -the pre-assembled functional unit with a paste-like mass, the functional unit is pushed with its open end ~the end shown at the left portion of Figure 10~ onto the stuf f ing tube ll of the stuffing machine, and the hollow body l is secured to the outer surface of the stuffing tube ll, as described above.
Although the hollow body of Figures 1-4 preferably has three of the web-like elements arranged symmetrically about the longitudinal axis of the hollow body, it will be recognized that the hollow body may have as few as two such web like elements or may have tJ~)2~
more than three of the ~eb-like elements. As ShOWn in the drawings, the web-like elements preferably lie in a common plane perpendicular to the longitudinal axis of the hollow body and each web-like element is arranged along a secant of the generally circular circumferential wall of the hollow body. It will further be recognized that the spacing of brake element 18 (schematically shown in Figure 9) from the hollow body may be variable.
While the invention has been described a~ove in te~s of certain preferred embodiments, the skilled artisan will readily appreciate that various modifi-cations, changes, omissions and substitutions may be made without departing from the spirit of the invention.
It is intended, therefore, that the present invention be limited solely by the scope of the following claims.
Por a number of reasons, it is desirable that the diameter of the sausages thus produced remains constant over their entire length. Optimum filling of the tubular casing requires that a uni~orm diameter, khe size of which is dependent upon the particular - casing, be maintained over the entire length of the casing.

The deshirred portlon of the tubular casiny extendiny over the external surface of the annular hollow body is located outside the protective cover, and cne of the annulæ disks is directly adjacent to one end of the hollow bcdy.
~hen the ~hus pre assembled functional unit is to be filled, the shirred tubular casing is pushed with its open end cnto the stuffing tube of thestuffing machine and the hollow bcdy is secured to the external surface of the stuffing tube by means of the locking mem~ers provided on its internal circ~Imfer-ence, for ex~ ple, the resilient web-like elements or the Seeger ring ~an expand-able securing ring). A paste~like mass, such as a sausage mixture~ is pressed out of the stuffing tube into the tubuk~r casing, while the tubular casing slides through the central circular opening of the annular disk and subsequently over the circumferential outer surface of the hollcw body, whereby the tubular casingis deshirred and sm~othed. The diamPter of the central d rcular opening of the annular disk must be suitably large; advantageo~sly, it is at least as large as the inte mal diameter of the shirred tubulæ casing.

escription of the Preferred Emtodiments As shown in Figures 1-3, an annular hollow body 1 has an external dia-meter which increases - from a first end 2 -to a second end 3 - -to a m~ximum value. The annular hollow bcdy thus has a closed external circumferential sur-faoe 4. The internal circumference of the hollow body is provided with three ~eb-like ele~.ents 5 which have a resilien-t spring action and which have curvededges 6 lying in planes parallel to the longitudinal axis of the hollcw body 1.
Figure 3A sh~s a modified form of the hollow body of Figures 1-3.
Viewed in front elevation, the mLdified hollow body of Figure 3A appears the same as shcwn in Figure 1. However, when viewed in the sectional side elevation view of Figure 3A, it can be seen that each web-like element 5' has only a single curved edge 6'. Except for this difference, the modified hollow body 1' of Figure 3A is identical to the hollow body 1 of Figures 1-3.
Figures 4 and 5 shcw a further embodiment of the annular hollow body 1~
having a Seeger ring (an expandable securing ring) 7 rather than the web-like ele-ments. The Seeger ring 7 is joined to two steps 8 and to the internal circumfer-ence of the hollcw body 1 at a base area 9. Beveled inner edges 10 enyage grooves 12 of a stuffing tube 11 (Fiyure 6); recesses 17 of the Seeyer ring 7 are necessary for the passage over bosses 14 of the stuff:ing tube 11.
In E'igures 6, 7 and 8 the annular hollow body 1 of Figure 1 ls shcwn pushed onto a stufE.ing tube 11, with each of its web-like elements 5 en~aging recesses or grooves 12 in the stuffing tube 11. In order to remove hollow bcdy 1from the stufflng tube 11, the annular hollcw body 1 is rotated in the directionof the arrow 13 (Figure 6), whereby the web-like elements 5 are resiliently biased onto the bosses 14 of the stuffing tube 11 (Figure 7), so that the annular hollow .~
body 1 may be pulled off the stufflng tube 11. With hollow bocly l removed, a shirred tubular casing 15 (Figure 8) may be mounted on the stuffing tube 11;
the tubular casing slides over the external surface 4 of the remounted annular hollow body l, whereby it is deshirred and smoothed.
Figure 9 shows in sectional side elevation view an arrangement in which a paste-like sausage mixture 16 is forced into the tubular casing 15 from a stuffing tube ll. The casing ~5 is in the shirred state on the stuffing tube ll; it slides over the annular hollow body l and through a brake element 18, and then passes through a schematically-represented cutting station l9 and tying station 20. Arrangements of this type are described, for example, in U.S.
Patent Nos. 4,017,941 and 4,077,090.
In Figure lO, a pre-assembled functional casing unit is represented; which comprises the shirred tubular casing 15 with a deshirred end portion thereof drawn over the hollow body l and closed off. A
protective covering 21 surrounds tile shirred tubular casing 15 and passes around annular disks 22. It ls turned back to the middle of the tubular casing and joined by means of heat sealing with the part of the protective covering surrounding the shirred tubular casing 15. In order to fill -the pre-assembled functional unit with a paste-like mass, the functional unit is pushed with its open end ~the end shown at the left portion of Figure 10~ onto the stuf f ing tube ll of the stuffing machine, and the hollow body l is secured to the outer surface of the stuffing tube ll, as described above.
Although the hollow body of Figures 1-4 preferably has three of the web-like elements arranged symmetrically about the longitudinal axis of the hollow body, it will be recognized that the hollow body may have as few as two such web like elements or may have tJ~)2~
more than three of the ~eb-like elements. As ShOWn in the drawings, the web-like elements preferably lie in a common plane perpendicular to the longitudinal axis of the hollow body and each web-like element is arranged along a secant of the generally circular circumferential wall of the hollow body. It will further be recognized that the spacing of brake element 18 (schematically shown in Figure 9) from the hollow body may be variable.
While the invention has been described a~ove in te~s of certain preferred embodiments, the skilled artisan will readily appreciate that various modifi-cations, changes, omissions and substitutions may be made without departing from the spirit of the invention.
It is intended, therefore, that the present invention be limited solely by the scope of the following claims.
