ABSTRACT:
Yarn feeding and changing apparatus for multi-feed sinker top circular knitting machines having a single circle of needles, wherein a yarn striper box is placed within the needle circle at each feed of the machine to provide a circle of boxes, and wherein a remotely programmed yarn selector is provided within the circle of boxes, the yarn selector and the circle of needles rotating in unison relative to the circle of yarn boxes. Each striper box is provided with a plurality of yarn feeding fingers and with a rocker, a control jack, and a clamp and cutter individual to each finger, the jacks controlling the rockers to move the fingers between feeding and idle positions. The yarn selector acts on the jacks to provide a yarn selection individual to each of the boxes. Each clamp and cutter is partially opened by its related rocker when its related yarn finger is moved to idle position and is thereafter fully opened and closed by the yarn selector. The clamp and cutter of a related yarn being moved to feeding position is retained in closed position by its related rocker during the yarn change. A yarn guide member causes each incoming one of the plurality of yarns to be fed to the needles at the same place in the needle circle.
