Patented Dec. 31, 1935 UNITED STATES PATENT OFFICE BEAMING MACHINE FOR CROS WINDING muy Application July 11, 1933, Serial No. 679,957 In Germany August 17, 1932 8 Claims.

'Ihe wet treatment of yarn, that is bleaching, dyeing and the like, on a perforated beam is generally known in itself. However, by employing beams of the ordinary winding-formation, the

` dyeing-through is irregular, because it is diicult to carry out an evenly loose formation of the yarn-body. It has therefore been attempted to wind the warp beams in a self-supporting crosswound cheese shape in order thereby to obtain a porous yarn body. But such warp beams of the customary cross-wind show again the drawback that the two sides of the yarn-body taper off owing to the pronounced crossing of the threads. r As a consequence, the outermost threads coming to rest on a constantly decreasing diameter, become shorter and shorter, and break when running-off the beam in consequence of the increasing tension.

The present invention has for its object to do away with this ldrawback of self-supporting cross-wound warp beams by carrying out the winding-on at the sides of the yarn body more densely, so that the yarn body is cylindrical up 2 to the ends, or only very slightly tapered at the sides, so as to show no drawbacks in practice. This can be obtained in several fashions, either by running-on the threads towards the sides of the yarn body in the full width of the traverse of the guiding comb, but in greater density in the comb,-or by opposing to the outer-threads between the guiding' comb and the running-on `point a stationary or movable resistance so that the threads do not run-on in the full width of the traverse at the sides of the yarn body, but with greater density.

An arrangement for denser winding-on at the two sides of the yarn body, represented and described in the patent application Serial No. 606,240, filed April 19, 1932, consists in reducing the distance of the comb teeth towards the ends of the yarn body in the full width of the comb traverse, so that the threads come to lie closer and closer together towards the sides of the yarn body.

The same object can be obtained by leaving the distance of the comb-teeth unchanged, and increasing instead the number of ends in each dent Von either side of the yarn body in the approxi- 50 mate width of the comb traverse, so that by way of example there are two ends in a dent over the cylindrical part of the yarn body, three ends in theiirst dent of that part of the comb where the yarn body would otherwise begin to taper-off, 55 four ends in the next dent, and so on.

i The invention is best illustrated by the following description of several embodiments thereof, taken in conjunction with the accompanying drawings, wherein:

Fig. 1 is a sectional view of one embodiment 5 of the invention,

Fig. 2 is a plan view corresponding to Fig. 1,

Fig. 3 is an upright left end view of Fig. 2,

Fig. 4 is a sectional view of another embodiment of the invention, 10

Fig. 5 is a plan view corresponding to Fig. 4,

Fig. 6 is an upright left end View of Fig. 5, and

Fig. 'l is a plan view of a modied arrangement for beaming several spools on a single shaft.

Figures 1 to 5 of the drawings show two embodiments of an arrangement by which the traverse of the outermost threads is reduced by resistances arranged between the guiding comb and the running-on point, so that the threads run-on more densely towards the ends of the yarn body.

In the illustration, I are the threads to be wound-on, 2 is the warp beam body, 3 the guide comb, 4 the comb rod, 5 the cam for traversing the guide comb, 5a the cam shaft driving the 25 cam. The guide comb and the cam shaft 5a are supported in a cradle with side arms 6, 1, and are susceptible of being balanced by counterpoiseweights.

In the embodiment shown in Figs. 1 to- 3, the cam shaft carries a loose bush 33 fitted with a wire loop 32 having lateral stops 32a, 32h for the reduction of the traverse of the threads adjacent the edges. The bush 33 with the wire-loop 32 is traversed on the cam shaft 5a, by means of a separate lever arrangement 34-35. The traversing movement is derived from the comb rod 4 and reduced as against the traverse of the comb, by means of the arrangement of the lever 35 with lever 34. The degree of shortening can be adjusted by shifting the pivot 36 in the slot of the lever 34. Moreover, the lever 34 may be of a different order, and may be pivotally connected at its end to lever 35, which in turn is pivoted to the bush 33. The wire-loop 32 with its stops 32a 45 and 32h therefore constantly has a shorter traverse than the comb 3. As a consequence, the outer threads are prevented from making their traverse and they are consequently crowded as shown particularly in Figs. 2 and 3, so that the 50 yarn body'receivves a cylindrical shape up to the sides.

l In the embodiment shown in Figs. 4 to 6, separate lstop wires 32aI and 32h are provided instead of the wire loop 32. In this case, the wires receive no traversing movement at all, but they are rmly carried in the cradle arms 6 and 1. Their adjustment to the yarn-body is such that on traversing the comb 3, the outer threads of either side are alternately prevented from following the full traverse and they are thereby crowded, for the same purpose as described above. In order to cause the crowding action to be carried out in such a fashion that the density increases towards the sides of the yarn body, the stops 32a. and 32h are in this case not bent at right angles to the longitudinal axis of the comb, as shown in Figs. 1 to 3, but on the slant, as particularly shown in Fig. 6, or in the shape of a curve. In Fig. 7, a number of separate warp-cheeses are shown side by side. In this case, the stops 320; and 32h are combined to form loops 32 the same as in the embodiment shown in Figs. 1-3. However, in this case, the loops 32 receive no traverse motion, just as in the example shown in Figs. 4 to 6. They are secured to a through-shaft 3l carried by the cradle levers 5 and l'. For this set of adjacent warp-cheeses, the eiect of these stops is the same as for the single warp beam.
