A latch needle for knitting machines has a needle latch supported such that t is pivotable in an undamped manner, and the seating surface on the latch spine is formed in wedge shape with converging surfaces. Seating surfaces adapted to the seating surface on the latch spine are provided on the upper edges of the side portions of the longitudinal slot of the needle, and this longitudinal slot is provided, in the region below the latch pivot, with an aperture or slit extending to the lower edge of the needle shank. In order to intercept the needle latch in a damped, substantially bounce-free manner when the latch, in its open or rearward position, meets the seating surfaces on the upper edges of the side portions of the longitudinal needle slot, the side portions of the shank beneath the seating surface for the latch are formed with longitudinal slots, or with through-slits to provide a region of increased elastic deformability in the two shank side portions defining the longitudinal slot and/or in the shank below the seating surfaces.

Resilient impact-type latch needle for knitting machine

To enable the latch (5) of a latch needle to be capable of absorbing great tresses without danger of damage to the needle latch, or to the needle itself, the latch has at least one through-aperture (11, 19) or opening in the region between its pivot bore (8) and the latch spoon (9).

Latch needle for a textile machine

A latch needle for knitting machines has a hook and needle shank and a latch pivotally mounted in a longitudinal slot in the needle shank with the faces of the needle shank flanking the longitudinal slot having support portions recessed relative to the upper edge of the needle shank for supporting a widened portion of the rear part or spine of the latch. A short portion of the longitudinal slot contains an aperture leading to the lower edge of the needle shank, and a further portion of the longitudinal slot adjacent to the short portion is deeper than half the height of the needle shank and projects in length beyond the end of the latch in its rearward open position displaced away from the hook. The support portions of the shank for the widened portion of the spine of the latch are located over the inner starting region of the further portion of the longitudinal slot.
