Gladbach, Germany Application August 10, 1954, Serial No. 448,817 Claims priority, application Germany August 11, 1953 8 Claims. (Cl. 118-33) The present invention relates to a textile treating process and apparatus.

In the tretament of certain textiles, a band of textile iibers is treated in a sizing bath or the like by being moved therethrough, and it is customary to compress the bers before they are submerged in the bath. However, the desired results are not always obtained because the fibers contact the open air after being compressed and before being submerged in the bath. Furthermore, it is often desired to compress the fibers after being treated in the liquid bath, but here again the contact of the fibers with air detracts from the desired results. Also, it is generally very difficult to properly regulate the force with which the fibers are compressed.

One of the objects of the present invention is to provide a process and apparatus overcoming the above drawbacks by compressing textile fibers twice both before and after the textile fibers are treated in a liquid bath and without allowing the textile fibers to contact the outer atmosphere.

Also, it is an object of the present invention to regulate the force with which the libers are compressed in a fully automatic manner.

In addition, it is an object of the present invention to regulate the driving of compression rollers in accordance with the effect of the liquid bath on the bers and in a fully automatic manner.

Further, it is an object of the present invention to provide a means for adjusting one of each of two pairs of compression rollers in such a manner that the adjustment ofy one roller is dilerent from the adjustment of the other l roller.

With the above objects in view mainly consists of a textile treating apparatus which includes a tank adapted to have a liquid textile treating medium therein. Two rst compression rollers are turnably mounted above a tank; these rollers are spaced from each other and extend at least partly into the tank, and thereby into the bath composed of said liquid medium. Two second compression rollers are located in the space between said iirst rollers so that each of the second rollers is in a position adjacent to and parallel with one of the first rollers, respectively, and so that the second rollers also extend at least partly into the tank and into the bath therein. An adjustment means is operatively connected to the second rollers for adjusting the position thereof with respect to the first rollers, respectively.

The novel features which are considered as characteristic for the invention are set forth in particular in the appended claims. The invention itself, however, both as to its construction and its method of operation, together with additional objects and advantages thereof, will be best understood from the following description of specific embodiments when read in connection with the accompanying drawings, in which:

Fig. l illustrates diagrammatically one embodiment of the invention in partly sectional elevation, the front wall of the machine frame being omitted, the section being the present invention 2,884,893 Patented May 5, 1959 taken along line I-I of Fig. 1b; Fig. 1a illustrates the drive means for the rollers of Fig. 1 in a fragmentary plan view; Fig. 1b is a diagrammatic partial end view of the embodiment of Fig. 1, partly sectional along line lb--Ib thereof; Fig. 2 illustrates in a partly sectional diagrammatic elevation a different embodiment, the section being taken along line II-lI of Fig. 2a, the front wall of the machine frame being omitted and also the roller drive means being omitted from Fig. 2 inasmuch as it is the same as that of Fig. 1; and Fig. 2a is a partial diagrammatic end view of the embodiment of Fig. 2, partly sectioned along line IIa-lla thereof.

Referring now to the drawings, it will be seen that within a frame A a tank 1 is provided to hold a bath of liquid treating medium such as a sizing liquid. Two substantially horizontal compression rollers 2 and 3 are turnably mounted above the tank 1 and are spaced from each other while extending across the tank 1 between two of its walls. The rollers 2 and 3 are mounted for rotation about horizontal or substantially horizontal axes which are substantially parallel with each other. The bearings 2 and 3 for the rollers 2 and 3, respectively, may be mounted directly on the walls of the tank or, as illustrated, on a lower portion A" of frame A which is connected to the tank.

Two other compression rollers 4 and 5 respectively cooperate with the compression rollers 2 and 3, the rollers 2, 4 forming one cooperating pair of compression rollers while the rollers 3, 5 form the second pair of cooperating compression rollers. In the embodiment of Figs. l, la, lb the rollers 4 and 5 are interconnected by arms 6 and 7 of a toggle linkage. A bar 10 is pivotally connected at the junction of arms 6 and 7. As is apparent from Fig. 1, a spring 11 is interposed between the bar 10 and an actuating mechanism comprising a hydraulic or pneumatic system 15, 16, made up of cylinder 16 and a piston 15 connected with a suitable source of iiuid under pressure so as to actuate the bar 10, piston 15 being connected to the bar 10 as shown in Fig. l. A second hydraulic system 17, 18 in the form of a cylinder 18 and piston 17 may be connected to the first system 15, 16, as by having the piston 17 provided with a duct 17' for forcing pressure fluid through the perforated end of cylinder 16. This arrangement is of particular advantage when several iniluencing factors are used to actuate the linkage 6, 7.

As can be seen from Fig. l, whenever pressure is exerted by piston 15 and rod 10 on the joint between the toggle arms 6 and 7, the linkage acts to move the rollers 4 and 5, with their bearings 4 and 5', respectively, sliding on the supporting walls of the tank or of the frame portion A", as illustrated, away from each other and against the corresponding rollers 2 and 3, respectively, and to compress ber material F passing between the cooperating pairs of rollers, as described further below. By reverse action of the piston 15 the rollers 4 and 5 can be lifted.

The rollers 2 and 3 are respectively driven by shafts 19 and 20 fixed to and carrying these rollers. The drive may be obtained from a common drive shaft 21, and with such an arrangement it is desirable to provide a differential mechanism or the like having a rotating shaft which may be braked, if desired, to equalize the drive between the two rollers 2 and 3.

It is preferred, however, to drive the shafts 19 and 20 separately as shown in Figs. la and lb where the shaft 21 is driven by a chain 22 and a sprocket wheel 23 while the shaft 19 is driven by a bevel gear drive 24, 25, a sprocket wheel 26, a chain 27, and a sprocket wheel 28. The bevel gear 25 and sprocket wheel 26 are carried by a sleeve 25' which is freely turnable on the shaft 21. A means for equalizing the drive of sprocket wheels 23 and 28 is located between these sprocket wheels or a drive t means 2.9 having an adjustable transmission ratio is located between these sprocket wheels.

The regulation of the transmission ratio is derived from a tension measuring device 3l) (Fig. 1) which is located between the rollers' 4 and 5 within the bath and measures the tension of the band of fibers submerged in the treating liquid. This vertically'm'ovable measuring device 3@ resting on the band of fibers may have any known construction and may be electrically, hydraulically, or pneumatically interconnected with the drive 29 for controlling the same, including e.g. a potentiometer Sil controlled by the device 3d and connected by wires 3d" with the drive 29 as is shown diagrammatically in Fig. l.

A roller 31 is located over the roller 2 and may be driven by the latter. The roller 31 serves to bring the bers F to the roller 2. A second roller 32 cooperates with the roller 31, as shown in Fig. l.

lt will be noted that the rollers 2 and 4' define a space above their contact line in which the treating liquid is located, and a pair of walls 33 may be carried by the bath against the end faces of rollers 2 and 4 to laterally limit the space above their common contact area and to raise the level of the treating liquid therein, particularly to the level of the line of contact between rollers 2 and 31. In both embodiments of the invention a back ller wiper 34 may be provided, as shown diagrammatically in Fig. 2. With the embodiment of Fig. 1 the material F to be treated moves over the roller 32, between the latter and the roller 31, around the roller 31 and to the roller 2 to be compressed between the rollers .2 and 31 and then' immediately submerged into the treating liquid. The band of iibers F then travels through 90 about the roller 2 and then is guided by the roller 4 deeper into the bath where the fibers then engage the measuring device 30 and then move on to the roller 5 which guides the fibers up to the roller 3 which compresses the iibers against the roller S before the iibers contact the outer air. After compression between rollers 3 and 5 the fibers are guided away to a drying apparatus, for example. in the embodiment of Figs. 2, 2a the roller 32 is omitted and only the rollers 31 and 2 form the rollers for feeding the bers into the bath.

Otherwise this embodiment diifers from that of Fig. l in that the rollers 4 and 5 are rotatably carried by a double-armed lever 3, 9 which in turn is pivotally connected at 11) with the end of rod 10. This rod 10 is operatively connected to an actuating mechanism 12 which is driventhrough a worm drive 13, 14 mounted in the frame A', the worm wheel 13 being threadedly connected to a screw-threaded extension of rod guided in a cylinder 12'. The worm drive 13, 14 may be electrically driven. As can be seen from Fig. 2, a vertical movement of rod 10 downwardly due to rotation of Wheel 13 causes rollers 4 and 5 to press against rollers 2 and 3, respectively, the bearing 5' of roller 5 being capable of sliding along the supporting wall of tank l or, as illustrated, of the frame portion A.

lf the tension of the fibers between the rollers 4 and 5' increases so as to register this increase on the device 3i), and if this increase exceeds a predetermined limit, then the device Si) regulates the drive 29 so that the ratio between the speeds of rotation of shafts 19 and 20 is adjusted in such a way that the shaft 19 rotates faster or the shaft Z9 rotates slower. In this way the tension of the fibers F between rollers 4 and 5 is necessarily lowered. On the other hand if the tension of the bers falls below a predetermined value the device 30 regulates the speeds of rotation of the shafts 19 and 20 in the opposite sense.

It will be understood that each of the elements described above, or two or more together, may also ind a useful application in other types of textile treating apparatus dilfering from the types described above.

While the invention has been illustrated and described as embodied in liquid textile treating apparatus, it is not if intended to be limited to the details shown, since various modifications and structural changes may be made without departing in any way from the spirit of the present invention.
