Abstract

A latch needle for machines producing knit goods includes a needle shank having a slot, a needle head, and a latch. The needle shank has a first longitudinal plane of symmetry and the slot has a second longitudinal plane of symmetry. The latch is pivotably supported in the slot in the needle shank so as to be pivotable about a latch axis extending transversely to the second longitudinal plane of symmetry of the slot. The second longitudinal plane of symmetry intersects the first longitudinal plane of symmetry at an acute angle.
