DEVICE FOR EXTRACTION OF KNITTING MACHINE NEEDLES Russian patent published in 1997 - IPC

FIELD: knitted fabric machine building, in particular, devices for extraction of circular knitting machine needles at production of tracery knitted fabric. SUBSTANCE: the device has axles according to the number of positions of the pushers, installed one above another, on which gates engageable through their working part with the pushers of the knitting needles are installed for turning, and control electromagnets formed by magnetic cores made of soft magnetic material with windings control magnet has on one arm of the magnetic core a permanent magnet with a pole shoe and an armature secured on the axle; the armature is made of soft magnetic material in the form of a bent plate, whose one end is connected to the gate through a driving link, and the other is placed in the gap between the magnetic core and pole shoe of the permanent magnet installed to close the magnetic circuit of the electromagnet when control voltage is applied to the windings and return to the initial state due to the field of the permanent magnet. EFFECT: enhanced speed of response and reliability, reduced weight and cost. 1 dwg
