ABSTRACT:
A circular knitting machine for the production of cut pile has latch needles (N) in the dial (R) and pile elements (11) in the cylinder (Z). Each pile element has an upper pile forming portion (11a) for example shaped like a hook, and also, spaced substantially therebelow, a cutting edge (11c) which cooperates with an opposed separate cutting edge (12c) of a cutting element (12). Cutting is effected thereby in the direction transverse to the axis of the cylinder (Z). Pile loops (H) are pulled downwardly by the fabric take down (arrow W) from the pile forming portion (11a) to the cutting edge (11c) sufficient time being available, before they are cut, to extend the pile loops (H) as desired and to tension the needle stitches over the just formed pile loops (H). The opposed cutting edge (12c) can be angled or skewed with respect to the cutting edge (11c) so that even with fine gauges, a real scissor action is guaranteed with only point contact of the cutters. Fine gauges are not excluded on account of the fact that the opposed cutting edges (12c) operate neither in the slot for the pile elements in the cylinder (Z) nor in the area of the needles (N).
