ABSTRACT:
A latch-type needle that is particularly suitable for knitting machines that work without sinkers includes a latch that preferably carries on its outermost end a cam or extension, the cam or extension is provided with a sliding surface. The sliding surface may move along a complementary sliding or runner surface and temporarily prevent the latch from pivoting out of its open position, for example. A corresponding wear of material is concentrated on the sliding surface. A damage, deformation or impairment of other parts of the spoon or latch head, in particular of either of its edges, is prevented.
