- up cross-wound warp beams, to an apparatus for other, difliculties arise in dyeing thoroughly the.

I carrying out the method, and to the product itself.

It is a well-known fact, that in the usual manner oi building-up warp beams, that is, in which the yarn windings run parallel beside one anyarn body. Consequently there has been a trend when running-oft the beam. Y

The present invention, which is a division of my application for Letters'Patent Serial No.

: 679,957,'filed-= July 11, 19?g3, has for its object to do away with the" drawback of the cross-wound {warp hitherto usual, which object is obtained by making the windings at the ends 'more ning more and more threads through each space' approaching the ends of the comb, for a section at each end equal in width to the traverse oi the comb. lies in each dental space of the comb at the central part of the-yarn body, one thread more is added at the'beginning oifthe comb traverse from inside to outside in-each' dental space or group of dental spaces, so that, for example, in the width of the comb traverse at each end 01 the guiding comb in one group of dental spaces cometo lie two threads, in the next group three threads, and in the next or outer group tom threads. Inthismannertheendsottheym'n body become correspondingly solid.

'lheinvention further provides, that the threads to be wound on are set more densely on the whole Ii thus, for example, one thread resented in the drawings.

, ll Claims. (Giza-37) This invention relates to a method oi buildingyarn body, so that an uneven yarn body is obtained. If, on the contrary, the yarn ribbon becomes narrower and narrower, the ends of the yarn body do taper to some extent, but the threads are no longer capable of cobwebbing, since they 3 have the necessary support.

In order that the invention may be clearly ans example in the accompanying drawings, in which 1 {Figure 1 is a part 01' the apparatus in top view,

in which the guiding comb is formed by a foldable zig-zag comb,

Figure 2 is an end view of the means for justingthe foldable comb, l.

Figures 3 and 4 are, respectively, end View and top view of the second embodiment, in which the guiding comb is constructed as a. spring comb;

Figures 5 and .6 show the'spring comb on en- .larged scale in cross section and end view.

It 'will be seen in Figures 1 and. 4*, that the edge of the yarn ribbon the threads are fed more I densely. Figure 4 in particular shows, that at the -edge of the yarn ribbon tour threads'lie in the in the remaining portion of the yarn first dental space, three threads in' the-subse- 2 body. This problem is solved by" making the spaces between the dents of equal width, but runquent dental space, two threads in the next and then, uniformly; one thread in each dental space. I wish to be understood that'this arrangement is only an example, because the numbers of threads as selected in practice cannot be distinctly As already mentioned, 1: denotes the'yam ribbon to be wound up, which is fed byarolier ya The thread guiding comb denoted by 3 is longitudinally shiitably mounted on arms ii.

To this end the teeth of the guiding comb are automatically to be adjusted denser and denser, which may be effected by constructing the guiding co'mb like a ioldable zlg-zag comb or as a spring comb.
