Application filed January 31, 1925. Serial No. 6,128.
' ihis invent-ion relates to the method of forming, cutting and scoring shells for rotary presses and the like and the means for carrying out such method.
An object of the invention is to provide a simple methoo of forming a shell for enveloping the cutting and scoring cylinder of arotar press and provide for the desired severing or scoring means or both whereby in combination with a suitable impression 'cylinderot the rotary press or the like, the
web of paper stock or the like is cut or scored or both pursuant to the desired outlines.
The cutting and scoring shell resulting from my invention is set forth and claimed in my copending application, entitled Cutting and scoring presses, Serial No. 6,127 filed by me on the 31st day of January, 1925.
The cutting and scoring shell is compositely formed of a partial cylindrical or other arcuate portion or strip of wood or metal or the like and out along contours conformingto the outline of severing and scoring desired to be efiectedupon theweb. At the lines ofcutting of the shell, the cutting and scoring knives are located, the cutting knives being sharp and. having the proper extension beyond the face of the shell to produce the severing oi the web in coaction with the impression cylinder. The scoring knives are similarly located at the lines of cutting of the shell but are dull and with lesser extension than the cutting knives.
Pursuant-to my invention, the cutting of the shell is efiected by means of a simple appliance comprising a band saw or reciprocating rectilinear saw and mounted on a suitable support providing for rotation in at least two directions transverse to one anothe of each strip of the composite shell to attain the lines of cutting of each shell strip in planes or curves as the case may be extending radially of the curvature ofeach shell strip.
Further features and objects of the invention will be more fully understood from the following description and the accompanying'drawings, in which- Fig. 1 is a perspective view of my appliance for cutting the shell along the desired contour; this figure shows the stage of beginning the cuttingot the shell;
Fig. 2 is a similar perspective view in an opposite direction, and showing an advanced stage'oit cutting of the shell;

Fig. i is a sectional elevation on line H of Fig; 1, on a reduced scale;
Fig. 5 is a perspective viewot a portion oi a composite shell provided with cutting and scoring knives, applied to a turtle or equivalent for mounting upon the cutting and scoring cylinder of a rotary press; and
Fig. 6 is a perspective view ofthe end portion of the shell and turtle mounted on the cuttin and scoring cylinder and the end portion or' an impression cylinder; this figure also shows a web passing between and cut and scored by the cutting and scoring cylinder.
As indicated hereinabove, the cutting and scoring shell 10'resulting from my method and means forming the present invention, is set forth and described in my aforesaid c0:- pending application Serial No. 6,127. One form of such cutting and scoring shell 10, as appears in Figs. 5 and 6 herein, is com.- positely stormed of strips of woodor metal which are out along the lines indicated at 11 11", 11, 11, 11 1 11 for example, for respectively locating the knives 12 12*, 12, 12, 12 ,12 12 for attaining the desired cutting or'scoring as the case may be. The plane or curved suri acesofcutting 11 to 1-1?- constitute the end faces of the respective adjacent strips designated 21,22, 23, 2 1, 2.5. 26, which end faces abut the respective cutting and scoring knives, 12 ,12 12, 12 12 and 12 Such strips 21 to 26 are secured to a suitable support by means of the screws 27 or equivalent, passing through suitable openings in the strips and tapped in the support.
As one form of such suitable support, as set forth in my aforesaid copend'ing application Serial No. 6,127, I may employ what I term a turtle 28, which may conveniently be formed or" semi-cylindrical halves 28 28", which are removably keyed to the cutting and scoring cylinder 29 of the rotary press, by means of the key-way 30, preferably formed jointly in the semi-cylindrical turtle halves 28*, 28 as at the line 31 of thejuncture of the turtle halves 28 28, for receiving the key 32 on the cutting and scoring cylinder 29, and locked thereto by means of the end slots 33 preferably on opposite sides of each of the juncture lines 31, 31 of the turtle halves 28, 28"; through each slot passes a screw or other removable headed, locking member.
The particular cutting and scoring shell 10 illustrated in the drawings is for cuttin a carton for a bar of soap or the like, and the group of cutting and scoring knives are duplicated longitudinally of the cutting and scoring cylinder 29, as in pairs designated 35, 36, which pairs 35, 36 of groups of cuttim and scoring knives are duplicated an integral number circiunferentially about the cutting and scoring cylinder 29. Such arrangement provides for minimum waste of paper on the web.
As is more fully set forth in my aforesaid copending application, my cutting and scoring shell 10 is adapted to be formed of dif ferent diameters of the composite or madeup shells, the different diameters providing for groups of cutting and scoring knives constituting an integral number circumferentially about its shell.
For the different diameter of shells, I provide turtles of corresponding radial thicknesses, the inner diameter of each turtle corresponding to the outer diameter of the particular cutting and scoring cylinder 29 on which they are to be assembled and the outer diameters of the different turtles make up for the difierences in inner diameters of the respective composite cutting and scoring shells.
Such arrangement affords the use of strips for the made-up cutting and scoring shell of substantially uniform thickness, or radial dimension.
Also, as is set forth in my aforesaid copending application, I arrange for the ad j ustable mounting of the oppositely disposed shaft ends 29 of the cutting and scoring cylinder 29 and the oppositely disposed shaft ends 37 of the impression cylinder 37, to accommodate for the resulting different diameters of the made-up cutting and scoring shells as above described and also to provide for the substantially straight line of feeding of the web 38 of paper stock between the cutting and scoring shell 10 and the impression cylinder 37.
As is indicated in Fig. 6, the cutting and scoring shell is applicable for use with a rotary press for impressing the printed matter 39 on the web in advance of the cutting and scoring operation. 7
Pursuant to the present invention. each strip, see 40 Figs. 1, 2 and 3. is preferably of uniform thickness or radial dimension indicated at its opposite end faces 41, On the upper face e3, see Figs. 1 and :2, is pencilled or otherwise marked the line of mark ing 4.4; corresponding to the desired location of the cutting and scoring knives. The strip 40 thus marked is placed upon an appliance as illustrated in Figs. 1, 2 and 3, described more particularly hereinafter, whereby the lines of cutting of each strip 40 is attained substantially radially of the curvature of the strip 40.
A preferred form of such appliance comprises the pair of rollers -15, 46 having outer diameters conforming to the inner diameters of the shell strip 40. The rollers l5, l6 are idly mounted to rotate either alone or jointly on a common axis which is substantially horizontal and the rollers -l5, d6 are mounted to be jointly or separately bodily rotated about an axis which is substantially vertical.
As one simple means of attaining the above results, the roller a5, see Fig. 1, is provided with a stud shaft 47 passing through its central opening; the stud shaft 4:7 is received in the flanged opening -18 of the bracket 49. The bracket 49 removably secured at one end of the table 50. The other roller l6 is similarly provided with a stud shaft 51 received through its central opening and fixed in the flange opening of the bracket 53, removably secured to the opposite end ail of the table 50. The rollers l5, l6 are of less length than the length between the brackets 49, 53, to provide for the clearance 55 between the flat end faces of the rollers 45, 46.
The band saw 56 or equivalent sawing member is suitably mounted to pass through the clearance 55; for an endless band saw, as indicated in the drawings, the same continues through the slot 57 formed in the vertical standard 58, at the upper end of which the table 50 is suitably mounted for horizontal rotation. The standard 58 is suitably secured at its lower end to a table, work bench, or other suitable horizontal support, which is provided with a slot similar to the slot 57 for the transit of the band saw 56. The band saw 56 passes above my appliance over a pulley (not shown) in the usual manner, as will be understood.
The plate 59 is secured by the screws 60, see Figs. 1, 2 and 3, to the table 50, closely adjacent its opening 61 through which the upper end of the standard 58 projects; the plate 59 ser es as a bearing and aligning means.
The rollers 45, 4-6 are idly mounted in their respective standards 49. to preclude displacement axially of the same.
As one means of providing the aforesaid mounting of the rollers 45, 46 and to also facilitate the substitution of rollers 45, 46 of different diameters, the following construction may be employed. The stud shaft 47 is enlarged at its end 47. see Fig. l, which is received within the flanged opening 48 of the bracket 49 by means of a set screw 62, and the free end of the stud shaft 47=is provided with the retaining plate 63 removably secured to the free end of the stud shaft 47 by means of the tightening screw 64. Such retalning plate 63 is prefer-ably circular and, countersunk within the opening in the flat end face of the roller 45. The bracket 49 is removed from the table 50 by removing its two or more set screws 66. 7
Similarly, thestud shaft 51 of the idle roller 46 is enlarged at its end 51 which is received within the flanged opening 52 of the bracket 53 and fixed thereto by means of the set screw 67. At the free end of the stud's'haft 51 is similarly provided the preferred circularretaining plate 68 removably secured by the set screw 69 and countersunk within the opening 70 in the flat end face of the roller 46. The bracket53 is removed from the table 50 by means of two or more set screws 71.
Returning to the cuttingof the line of marking 44, upon initiating the cutting by the band saw 56, see Fig. 1, at the edge 41 of the shell strip 40, the shell strip 40 is fed to the band saw 56 in the direction of the contour of the line of marking 44. Thus, for the straight line of the portion 44 beginning at the edge 41, the shell strip 40 is slid horizontally over the roller 46 progressively as the cutting is performed by the band saw 56, such progressive pushing of the shell strip 40 ventually bringing the shell strip 40 also over the idle roller 45, the aforesaid movement of the shell strip 40 being performed without rotation of either of the rollers 46, 45 and without rotating the table 50 about its standard 58, which movement is continued until the curved portion 44 of the line of marking 44 is reached. At this stage, the shell strip 40 is supported on the idle rollers 45, 46 jointly without rotation of the same about their respective shafts 47, 51, but the table 50 is turned in the direction of the arrow 72, see Fig. 1, until the straight portion 44 of the line of marking 44 is reached. The portion 44 is substan tially at right angles to the previous straight portion 44. The cuttlng along the straight portion 44 is attained by pushing the shell strip 40 to rotate the rollers 45, 46 jointly in the direction of the arrow 73, see Fig. 1. and without rotating the table 50. The cutting of the curved portion 44 is similar but in the reversed direction to that of the cutting of the curved portion 44 and the cutting of the straight portion 44 is similar to and in the same direction at the cutting of the aforesaid straight portion 44.
Fig. 2 shows the band saw 56 at the completion of the cutting of the next curved portion 44, which is effected by rotating the table 50 in the direction of the arrow 74, and the continuance of the cutting along the portion 44 see Fig. 2, is attained by pushing the shell strip 40 to jointly rotate the rollers 45, 46 in the direction of the arrow 75, while keeping the table quiescent.
The aforesaid line of marking 44 corresponds generally to the cutting of the par ticular shell strip 22,'see Figs. 5 and 6, and at the effective portions of the resulting cut faces, the knives-in this case cutting knives-designated 12 to 12 are located and frictionally secured in position by the abutting shell strip 77 by means of the screws 27, as referred to hereinabove.
In Fig. 5, l have indicated the aforesaid particular shell strip 22 in position on the turtle 28 and the locking shell strip 77 about to be positioned by means of its screws The knives 12 12 and 12 are indicated in their respective positions at the cut faces of the particular shell strip 76 and the knives 124, 12 and 12 about to be placed at their respective positions.
As will appear from the aforesaid method of cutting of the shell strips by means of 7 my aforesaid appliance, each line of cutting whether straight or curved is located in a radial direction relative to the center of curvature of the shell strip.
By reason of the relative short length of arc of the strips compositely forming my cutting and scoring shell, strips of substantially the same inner and outer diameters respectively may be employed for compositely forming the shells of difierent outer diame ters, whereby a stock of uniform shell strips is made possible.
It is convenient in the assembly on and disassembly from the cylinder of my combined turtle. and cutting and scoring shell to locate a line of juncture between two strips coincident with each line of juncture of the turtle halves, whereby the combined turtle and cutting and scoring shell is assembled and disassembled without disturbing the shell strips thereon.
Itwill be perceived that the rolls 45, 46 may be in the form of cylinders fixedly secured to their respective stud shafts, or half cylinders or like partial cylinders be employed. in lieu of the idly revolving rolls 45, 46, in which circumstance the rotation of each shell strip in the cutting stage thereof is slid about the cylindrical curvature of such cylinders 45, 46 instead of rotation of the rolls 45, 46. Such half or other partial cylin- dricals 45, 46 may be fixedly mounted on their flatfaces on the horizontally rotating table 50.
In a similar manner, my invention is applicable for forming cutting and scoring shells of curved formation other than circular or cylindrical, by the use of shell strips of corresponding curvature. 1
Vhereas, I have described my invention by reference to specific forms thereof, it will be understood that many changes and modifications may be made Without departing from the spirit of the invention.
I claim 1. The method of forming curved cutting and scoring shells, which comprises providing strips of curved formation and cutting the strips along paths of cutting extending 'adially relative to the curvature of the strip between the cut portions of the strip corre sponding to the desired positions of the cutting and scoring rules.
2. The method of forming curved cutting and scoring shells, which comprises providing strips of curved formation and cutting the strips along paths of cutting extending radially relative to the curvature of the strip between the cut portions of the strip corresponding to the desired positions of the cutting and scoring rules and applying the strips to a suitable support to extend on such support in the direction of length thereof.
3. Means for forn'iing cutting and scoring shells compositely formed of curved strips, comprising a base, a vertical standard for rotatably mounting said base, a pair of horizontally aligned curved supports for the strip secured in spaced relation to one another on said base and a severing member attending through the space between said curved supports.
4. Means for forming cutting and scoring shells compositely formed of curved strips, comprising a base, removable means including a standard for rotatably mounting said base, a pair of horizontally aligned curved supports for the strip secured in spaced relation to one another on said base and a severing member extending through the space between said curved supports.
Means for forming cutting and scoring shells compositel y formed of curved strips, comprising a base, removable means including a standard for rotatably mounting said base, a pair of spaced, aligned rolls and having cylindrical work engaging surfaces, removable means for rotatably mounting said rolls, and a band saw extending through the clearances between said spaced rolls.
In testimony whereof I have signed this specification this 23 day of January 1925.
