ABSTRACT:
Needle beds are provided with needles, needle jacks and select jacks and selectors, and the selectors are provided with three butts. The front butt is made to contact the reference plane of the carriage to serve as the fulcrum of rocking. The second butt is used to withdraw the selector, and the tail butt is used to advance the selector. Two pressing cams of the carriage press the tail butt to make the selector to be attracted by a permanent magnet. Two raising cams of the carriage advance the selector to the H position and the A position.
