Title: Stop device for knitting machine - which automatically stops re-sets and re-starts following excessive yarn tension
Inventor: LEVIN NATHAN
IPC: D04B35/12
Filed: 1973-01-26
Abstract: The stop device has a main shaft extending from supports on the front of the creel. A series of equally spaced brackets are connected to the main shaft by rotatable shafts journalled in slots. A number of yarn arms are rotatably supported on the subsidiary shafts and they can move between a normal and a down position. A series of movable latches are supported on bars attached to the brackets and they are individually operative relative to the yarn arms to maintain the latter in their normal positions. When the journalled shafts move between their two positions, a re-setting shaft is also moved to one of two positions. These correspond to a limit stop position for the yarn arm, and the normal operating position. Movement of the latches makes and breaks an electrical contact to start and stop the machine and operate a pneumatic air valve to reset the yarn arm. The device is fully automatic and self-contained and may be attached to a grid or base plate on the knitting machine.
