Abstract

The kinematic chain includes a threaded nut on the threaded motor shaft, the nut driving a crank lifting a thrust bearing supporting the needle cylinder on a pivot in gimbals. The motor shaft carries a position determining potentiometer which feeds a signal to an electronic circuit including trimmer resistors which can be preset to give a desired sequence of signals reversing the motor at different motor shaft positions, giving a desired programme of cylinder lifts of different amts. to vary stitch size.
