However, when such a method is used for twilling of glass fibers, the warp of the glass fibers is pierced by the needle tip of the easing machine and the yarn is separated, so that the warp of the glass fibers is damaged. There has been a problem of causing attachment, yarn breakage, and single yarn breakage. The present invention was created to solve such a problem, and an object of the present invention is to perform twilling in a warp preparation machine without using a leasing machine that adversely affects the warp group. There is to do.

[0004]

In order to achieve the above object, in the present invention, the movement and movement of the twilling comb can be performed without using a needle tip as a means for separating the arranged warp groups. The problem is solved by the vertical movement of the corresponding traverse rod. That is, the present invention provides a device for traversing a warp group of a woven fabric arranged in a sheet shape, aligned and wound around a loom beam in a warp preparation machine. It is composed of a take-up rod part, and has a structure in which the warp yarn group can be taken up and down by moving the take-up rod up and down in accordance with the lateral movement of the take-up comb according to a set program. .

[0010]

According to the present invention, a warp group arranged and arranged in a sheet form is divided into a certain unit, and the warp of each rank of the divided unit is set as a warp group, and the warp group is stepped. The inserted comb is reciprocally moved in the cross direction with the warp, and each time the operation is performed, it is sequentially lowered by the take-up rod portion, and these operations divide the warp group into upper and lower parts within the reed wing of the comb. After inserting the twill cord through the divided opening section, the warp threads arranged in a sheet shape are twilled by raising the twilling rod section. The reciprocating twill thread installed in the front stage of the loom beam is used. Since the take-up comb and the traversing rod part that moves up and down are used, it is possible to easily traverse the warp yarn with the twill cord before the yarn is wound on the loom beam in the warp preparation machine. Moreover, the conventional one that separates the warp at the needle point etc. Unlike, the warp can be regularly and quickly taken without damaging the warp. As described above, the automatic yarn take-up device of the present invention can be incorporated into a series of warp preparation machines, so that the warp yarns arranged in a sheet shape like the conventional one are temporarily wound and separated by a needle tip. The operation is simpler and the cost can be saved as compared with the case of using a traversing device.
