Abstract (en)
[origin: EP0866159A2] The latch needle, for a knitting machine, has the end section (10) of the latch shaft (9) shaped as a cam unit, supported by the spring (15). It has a chamfering (17) and/or a bent edge at the upper surface of the latch shaft which, with the spring (15), determines the back position and holds it there in place. The cam unit has a curved cam surface (18) towards the chamfering (17) or bent edge, which steadily decreases the radial gap from the axis (12) from the upper side of the latch shaft to the under side of the latch shaft.
