ABSTRACT:
A pile forming warp knitting machine having a spaced plurality of needles and a pair of separate sinker assemblies. These sinker assemblies have a plurality of pile sinkers and a plurality of enclosing, knock-over sinkers. Both pluralities of sinkers are interdigitated with the needles. The pile sinkers each have a distal edge and a proximal edge. The knock-over sinkers each have an enclosing recess. The knock-over sinkers also have (a) an exposed first segment with a knock-over edge, (b) a second segment integral with the first segment, and (c) an enclosing nose integral with the second segment and having an inside edge extending alongside the second segment at a predetermined distance therefrom. In a first working mode the knock-over sinkers reciprocate relative to the needles between an enclosing position and a knock-over position. The enclosing position is at the enclosing recess. The knock-over position is external to the enclosing recess. In the first working mode the knock-over sinkers can establish pile height based upon the spacing between the distal edge of the pile sinkers and the inside edge of the enclosing nose. In a second working mode the enclosing, knock-over sinkers are retained in the knock-over position. In this second working mode, the enclosing, knock-over sinkers can establish pile height based upon spacing between the distal edge and the proximal edge of the pile sinkers.
