A cutting arrangement 20 serves for cutting the threads 12 between the clamping point 19 and the drum 1.

Abstract: A method of winding yarn into hanks, comprising the steps of loading a beam having a sheet of parallel ends of yarn wound thereon onto a rotatable beam stand; unwinding the sheet from the beam and passing the sheet through a nip between two reciprocating rolls; separating the parallel ends of yarn in the sheet from each other; and guiding each of the separated ends of yarn to a rotatable reel. The ends of yarn are then wound onto the rotatable reel by rotating the beam to release the sheet wound thereon; rotating the interacting rolls to draw the sheet through the nip; and rotating the reel to wind each separated end of yarn onto the reel. The rotational velocity of the beam and of the reciprocating rolls are controlled so as to keep the tension on the sheet of yarns below a defined value. By controlling tension, one reduces the likelihood of thread breakage and causes the yarns to be wound onto the reels in the form of loose hanks.

Abstract: Apparatus used with a yarn warper or beamer to uncross yarn ends that have become crossed during a warping operation. An element shaped like a knuckle moves back and forth across a side of the yarn sheet while protruding into the path of yarn ends making up that sheet. The motion of the knuckle against the side of the yarn sheet raises each yarn slightly, then allows the yarn to return to its original position. This motion dislodges yarn ends that have become crossed and allows them to return to their proper registration in the yarn sheet. The end uncrossing device may be located either downstream or upstream from the comb assembly in a warper.

Abstract: After yarn breakage, yarn loops are formed in an accumulator device (3) by rollers (13, 13') that are able to be displaced in relation to each other. The beam is rotated in reverse at a specific reverse speed (c) which is less than the accumulation speed of the accumulator rollers (13, 13'). The length difference arising from the difference between both the speeds is compensated by further withdrawal of yarns (a) from the creel (1) while the yarns are subjected to a defined braking tension of the individual yarn tensioners (7). Complex controls and speed synchronization are thus avoided.

Abstract: Continuous production of a long bias cloth is accomplished by manufacturing a tubular fabric on a circular loom having a circular frame, reeds arranged on the frame and a shuttle for a weft rotatable along the frame. The fabric is removed from the loom under tension by a removal device comprising a primary pillar core with a plurality of caterpillars adjacent its outer periphery. Removal under tension prevents the formation of any edge portion causing folds and wrinkles in the tubular fabric. The tubular fabric is then spirally cut by a cutting device which has a secondary pillar core with a plurality of feed rolls adjacent its outer periphery. The feed rolls are capable of moving the fabric forward relative to its length, while the cutter is capable of moving circumferentially relative to fabric lengbth. A long bias cloth of high quality can be manufactured continuously, even when the warp and weft fibers used have high-strength and poor or low elongation.
