ABSTRACT:
The latch needle (1) of the invention has a latch (7), which is provided on its free end, on its side facing away from the hook (3), with one or more recesses (18, 19). The function of these recesses is to reduce the moment of inertia of the latch (7), which leads to an increased service life of the latch. Between the recesses (18, 19), a rib remains, whose top side functions like a skid for loops to be transferred. The indentations (18, 19) are preferably elongated depressions. However, corresponding openings may be provided as a substitute instead.
