Process and warp knitting machine for the production of pile ware

Abstract

There is disclosed a process for the manufacture of pile ware on warp knitting machine. The machine has a single needle bar and pile sinkers. The base threads and the pile threads are contemporaneously laid about the needles. During the swing associated with the underlap into the overlap position, first the base threads and then the pile threads are laid onto the needle backs and slid off from said needle backs with separation from each other. The pile sinkers are led into the space between the base and pile threads during the swing-through and remain there until the knock-over of the stitch. There is further provided an apparatus for carrying out the above process by means of a warp knitting machine for the production of pile ware. The machine has a needle bar, laterally displaceable bars for base and pile threads and a laterally non-displaceable pile sinker bar carrying a pile sinker interacting with each needle gap. The pile sinker bar and the needle bar are so provided that in the rest position, the free ends of the pile sinkers do not protrude beyond the needle backs. In the pile forming position, the free ends of the pile sinkers protrude beyond the needle backs and are moveable to and fro. In operation the pile thread bar swings from the underlap position into the overlap position as the last guide bar. The machine also has a control arrangement that activates the forward movement when the guide bars are in or close to the overlap position. The pile sinkers are so oriented that their free ends pass between the pile threads and the base threads during the forward movement.
