ABSTRACT:
A latch needle for a loop-forming textile machine includes a needle shank; a sawslot provided in the needle shank and being defined by two parallel-extending needle shank cheeks; a rivet traversing the sawslot and being rotatably supported in the needle shank; a needle latch pivotally disposed in the sawslot and having a latch spoon and a rivet-receiving bore; and an elongated spring element having a first end anchored in the needle shank and a second end extending into the sawslot. In the closed position of the needle latch the second end of the spring element is in a pressing engagement with a support surface of the needle latch and resiliently urging the needle latch into an intermediate opening position. The needle latch has an open-ended recess extending from an end of the needle latch remote from the latch spoon into the rivet-receiving bore. The needle latch has a wall face defining the open-ended recess at one side thereof and carrying the support surface. The rivet is rigidly affixed to the needle latch.
