Abstract: A process and machine for the preparation of pile ware uses a single needle bedded warp knitting machine, having pile sinkers. During the swing-through of the guides subsequent to the underlap into the overlap position, first the ground threads and then the left pile threads, are laid to the rear of the needles, and run along these, with separation from each other. The pile sinkers are introduced into the space between the ground threads and the left pile threads, during or after the swing-through, and stay there until the knock-over of the stitch. The threads are provided to the guide bars in a one full/one empty order, only every second needle serving for stitch formation. The number of pile sinkers equals half of the number of needles. Right pile threads are provided which are overreached by the pile sinkers together with the ground threads laid about needles not serving for stitch formation and are then knocked over.

A guide reed is movably arranged between the pile yarn carriers and a pile sinker and includes a laying edge which crosses the pattern-forming pile yarn of the shed. The guide reed performs lateral and sinking movement to overlay the selected pile yarn.

Abstract: A thread control device of a weft knitting machine comprises a thread guide, which is fastened to a weft rod. The weft rod is mounted to be pivotable about its longitudinal axis and to be axially displaceable in supports, which in turn are movable at right angles to the axis. The weft rod is connected to be secure against rotation with a non-axially displaceable crank. A non-rotatable drive transfer member is reciprocatingly displaceable in a plane parallel to the axis by, for example, a pivot arm. A thrust member is articulated by ball joints to the crank and to the transfer member and in operation converts reciprocating motion of the transfer member into oscillatory pivotation of the crank. Such a thread control device makes high operating speeds possible and enables production of tapes with complicated patterns.

Abstract: The laying-in comb for a warp knitting machine has sinkers wherein the top edges are longitudinally offset relative to the bottom edges so as to impart rigidity to the sinkers. The amount of offset decreases from the securing end of the sinkers towards the head end of the sinkers. The sinkers may be permanently deformed by being cast into a mounting block or may be placed under tension by means of separate blocks which are movable relative to each other. The blocks may also be mounted on bars which are programmed in accordance with a suitable pattern.
