<p>Machine incorporates a yarn holder that traverses a warp sheet (A) having a means for holding thread tight at its borders. The holder has a no. of thread guides which simultaneously deliver a constant no. of threads. The machine has devices for stretching warp threads lengthwise of (A) the guides being traversed in a straight line w.r.t. the holder, which is swivelable about an axis positioned perpendicular to the centre of (A). A feed mechanism provides the swivelling action, consecutively moving the holder into one position where it is held, then to a second position, and then back to the first position.</p> |
