' In Germany July 2, 1931 Our invention relates to a machine for beaming yarn in cross winding, for bleaching and dyeing and like purposes.

The wet treatment of yarn, that means bleaching, dyeing and the like, on the beam is already known for decades, but has gained extraordi- The essence of this wet treatment consists in the yarn being wound on to a beam in a continuous course,

' quite like with the so-called warping frames used in weaving, the beam used, however, having the form of a perforated cylinder which after having been wrapped is inserted into the circulation of the liquor. The circulation is reversed from time. to time, so that the liquor oozes through the yarn layers surrounding the beam alternatively from outside to inside and inversely. Now, in order to obtain a satisfactory and uniform dyeing efiect it is necessary that the yarn in beaming is wound always with uniform tension and uniform density, in order that unifo'rm' resistance is offered throughout to the liquor oozing through the yarn layers. This winding has its difliculties and, therefore, no uniform dyeing effect is frequently obtained in the dyeing operation. This is of importance especially if several yarn beams have to be treated with one and the same liquor and, more particularly, in dyeing with bright colors.- As the threads on the beam lie close together and close upon one another, the liquor has not the possibility to advance everywhere and uniformly up to the individual threads, this being the case especially with the threads situated at the ends of the beam. For, on running on to the beam, these threads are urged axially inwardly by the of the beam and, therefore, frequently come to lie more closely on one another than the threads situated in the midst of the beam.

In order to overcome all the drawbacks mentioned, it has been suggested to wrap the yarn beams with cross winding, to obtain in this way a more porous yarn body orbobbin. With the machines proposed for this cross winding, however, the stationary axially moving comb p, as illustrated in the schematic Figure 1, is situated far away from the place where the threads run on to the beam. The consequence thereof is, that the stroke of the guide comb at that place results in a nearly parallel position of the threads and no marked crossing, and thus no suflicient porosity enabling an easy and uniform passage of the liquor is obtained. Furthermore, with cone warping frames it has been suggested to dispose,

the guide comb asnear as possible to the place where the yarn runs on to the beam. However,

also in this case, the place where the thread leaves the guide comb is not situated immediately in front of the place where the thread runs on to the beam, but so far away therefrom, that a satisfactory crossing of the threads is impossible. Cylindrical yarn bobbins as they are obtained by means of the machine according to the present invention, therefore cannot be produced by means of this known appliance. Furthermore, warps wound on cone warping frames cannot be used at all on the beams of these machines for the wet treatment, such as bleaching, dyeing or the like, buthave to be unwound on suitable special machineryand re-wound on to special dyeing beams. The object of our present invention is to remedy these drawbacks.

In the machine forming the subject-matter of the invention the guide comb, formed by a plu rality of teeth which are rigidly disposed at least in the direction of reciprocating movement of the comb, is disposed in close proximity to the place where the threads men to the beam, as illustrated in the schematic Figure '2. The threads thus always run from the guide comb directly on to the beam or the windings already existing thereon. The crossing of the threads caused by the axial reciprocating motion of the guide comb or beam thus has a full efiect upon the threads running on to the beam. In connection with such a supply of the threads, a beam fitted at its ends with flanges cannot be made use of, indeed, as

the flanges would laterally interfere with the course of the thread. Therefore such beams have to be employed, the flanges of which are removable,.or at least adapted to be displaced axially so far away from the ends of the yarn bobbin, that no interference with the course of the thread occurs. Furthermore, as the diameter of the bobbin permanently increases during the winding operation, the guide comb has torecede progressively from the beam in accordance with the gradually increasing diameter of the bobbin, 'in order to obtain the object aimed. at, namely the running of the thread from the guide comb directly on to the beam. This may be achieved in dif- R ferent ways: The guide comb or its carrier which advantageously is designed as atravelling roller, is either mounted on weight-loaded swing levers in such a manner that it adjusts itself quite auto- 50 arily, whilst the beam is mounted movably, forresulting therefrom. At all events, however, in

order to achieve the object aimed at, namely a satisfactory crossing of the threads even with a mechanically displaced guide comb or beam, the guide comb must always remain within the annular space that comes into question for the bobbin to be wound, as marked by the dotted lines in Figures 2 to 4 and to 10.

Fig. 1 shows the association of a guide comb with a yarn beam according to the prior art,

Fig. 2 shows the cooperation of a guide comb with a yarn beam according to the instant invention,

The Figures 3 to show several embodiments of the yarn beaming machine forming the subj'ect-matter'of our present invention.

Fig. 1 shows diagrammatically a yarn beam empty and in various stages of being loaded with yarn and an axially movable guide comb,p at a usual distance from the-body of the beam.

Fig. 2 shows a yarn beam 2 empty and in various stages of being loaded with yarn and an axially movable guide comb 3 controlling a group or groups of threads arranged tape-fashion side by side in a sheet. The threads bodily traverse the beam by means of the reciprocating guide comb 3, which is always kept in close proximity to the winding-on points on the beam in such a fashion that in the traversing operation, the threads of the group or of each group overlap each other in a way insuring a certain control of the mesh formation to a degree allowing an easy penetration of the liquor.

In the machine illustrated in Figures 3 and 4 the threads 1 coming from the creel run through the guide comb 3 to the perforated beam roller 2 which is mounted on a shaft 14 and receives rotary motion from a belt gear by means of an intermediate spur wheel gear train 12, 13. The guide comb 3 is carried by a rail 4 and receives its axial reciprocating motion by means of a cam disc 5, the shaft of which is mounted on swing levers 6, '7, which further carry the guide comb 3,.rotary motion being imparted to disc 5 by a chain drive 8, 9, 10. With increasing beam diameter, the guide comb 3 which rests on the bobbin, or the carrier 4 with the guide comb rises by virtue of its mounting on the weight-loaded swing levers 6. This change of position results in an alteration of the pressure exerted by the carrier upon the bobbin and, as a consequence thereof,

the yarn would be wound under different load, that means, with different density. In order to overcome this drawback, the weights 11 mounted on the swing levers 6, 7 are displacable. In order, further, to prevent jumping of the guide comb 3 by the yarn running to the beam, the weightloaded arms of the swing levers 6, 7, are guided between adjustable braking jaws 15.

Inversely, as schematically illustrated in Figure 5, the guide comb 3 may be mounted fixedly, while the beam 2 is movable and abuts with the windings thereon against the carrier 4 of the guide comb and is pressed down by the latter with increasing beam diameter. In accordance with the increasing diameter or weight of the beam, the counter-weights are automatically displaced along the rear arms of the swing levers 28 by means of rods 29 which are fulcrumed at 30 and linked at 31 to the weights 11.

If the guide comb has a uniform pitch on the entire width of the beam, as illustrated in Figure 6, the two front ends of the bobbin become rather inclined due to the strong crossing of the threads. This results in the fact that the marginal threads become shorter than the remaining ones and break when unwound, due to theirv greater tension. In order to avoid this disadvantage, according to the invention the dents and corresponding teeth of the guide comb .that are adjacent the two ends of the beam increase towards these ends gradually and uniformly. In this way so much more yarn is wound on these places, that the bobbin becomes cylindrical up to its both ends or tapers there only to a negligible extent.

The embodiment illustrated in Figure 7 of the machine forming the subject-matter of the invention differs from the embodiments hereinbefore described by the design of the guide comb 3. In this case, the guide comb 3 is not constructed as a single bar with the guide dents disposed in a straight line, but as is the case with the showing in Fig. 4, the same is composed of a plurality of sections spacedly fixed'in straight or inclined position on a common axially reciprocating carrier, (Figure 7). Each separator section serves to feed to the beam a group of threads. This peculiar feed of the threads in the form of ribbons results in the formation of disc-shaped cylindrical cross wound yarn bodies, as will be seen from Figure '7, which bodies according to the invention together form a complete warp beam. In this way the advantage is achieved for colored weaving, where the warps contain very many differently colored threads and very many narrow warps are employed, that individual cross wound disc-shaped bobbins may be withdrawn from beams formed in this way and dyed, which bobbins then' may be composed again so as to form a new multi-colored beam. According to the number of the threads to be wound and to the number of threads united in such a ribbon, the number of the bobbins to be formed varies, it is not subject to any limitation and the number may decrease to a single bobbin. In this latter case only one sole undivided cylindrical cross wound warp bobbin is formed on the beam.

- It may be stated that subdivided guide combs are already known in warping frames, but here they are expansion guide combs which do not admit formation of disc-shaped bobbins. For the production of the latter the guide comb sections must not form the continuation of one another, but have to be arranged spacedly from one another at a distance equal to the stroke of the reciprocating guide comb.

Furthermore, also the manufacture of cross wound yarn bodies on warping frames by means of ribbons composed of individual threids is already known, and also the simultaneous production of a series of juxtaposed cylindrical .cross wound bobbins by means of ribbon-like thread groups.

The embodiment of the invention illustrated in Figures 8 and 9 difiers from the embodiments hereinbefore described by the fact that the guide comb 3 with its carrier does notrest on the bobbin or bobbins, but is positively held, even with increasing diameter of. the latter, at a slight dison the machine frame.

tance therefrom. In the embodiment illustrated this positive distant adjustment of the guide comb is established in the following manner: The swing levers 6 and 7 which carry the guide comb 3 have pivotally mounted on them screw nuts 16 through which pass screw spindles 1'7. The latter rest in footstep bearings 18 likewise pivotally mounted The lower ends of the spindles 17 project beyond these bearings 18 and there each carries a bevel wheel 19 which is in mesh with a companion wheel 20 rigid to a shaft 21. The latter is mounted in the machine frame and outside the frame carries a ratchet wheel 22 which is turned from a crank disc 25, through the intermediary of transmission levers 23, 24, by a pawl 26 by the angular amount of two or more teeth in each revolution of the crank disc 25. By this motion, through the intermediary of the bevel gear 19, 20, also the spindles 17 are turned correspondingly, whereby the swing levers 6, 7 with the guide comb 3 carried by them are lifted. This movement may be varied by a greater or lesser swinging angular movement according to the thickness of the yarn and corresponding to the amount of increase of the diameter of the beam. When the beam is com.- pletely wrapped, the guide comb 3 can again be c lowered to its initial position relatively to a new blank beam by turning a hand wheel 26a, Figure 9. v

In the embodiment illustrated in Figure 10, the guide comb, in contrast to the arrangement shown in Figures 8 and 9, is .not swingingly mounted but is rigid, as in Figure5, while the beam is mounted for positive motion on swing levers 27,-

in order to obtain the desired permanent equal distance of the guide comb from the periphery of the bobbin or bobbins on the beam. The positive motion of the swing-levers 27 is produced by the same means as is shown in the embodiment of Figures 8 and 9.

' Also, in the embodiments illustrated .in the Figures 8 to 10 of the machine forming the subject-matter of the present invention, the winding of the beam may be carried out either by winding thereon one continuous bobbin or a plurality of bobbins from ribbon-like united yarn groups,

as in the embodiments shown in Figures '7 and 9.
