ABSTRACT:
A yarn changing apparatus for a multi-feed circular knitting machine includes lever arms connected to yarn feeding fingers. Vertically moveable sliders operatively connect to the lever arms and are slidable between raised and lowered positions to move the lever arms and yarn feeding fingers connected thereto, so as to place the yarn feeding fingers into operative and nonoperative positions. Vertically moveable rocking jacks pivotably connect to the sliders with each rocking jack including pivotably moveable upper and lower ends. Remotely programmed selection units are operative with the rocking jacks for aiding in pivoting the rocking jacks. The remotely programmed selection unit includes upper and lower electromagnetic block units which are energizable and act upon selectors to engage and pivot the rocking jacks. Raising and lowering cams engage the rocking jacks to raise and lower the rocking jacks during pivoting movement thereof so as to raise and lower the sliders and move the lever arms and yarn feeding fingers connected thereto between operative and nonoperative positions.
