ABSTRACT:
A method and apparatus for drawing and knitting yarn on a circular knitting machine which includes a needle cylinder, a sinker ring fixedly mounted on the cylinder and having a plurality of equally spaced, radially extending sinker grooves. Each groove contains a sinker having a step on its bottom surface adjacent the cylinder end of the sinker. The ring includes a well adjacent the needle cylinder and a shelf between the well and the sinker grooves. A cam occurs on the ring for sequentially moving the sinkers, one after the other, radially toward and radially away from the cylinder so that the bottom surfaces and steps on the sinkers engage the bottom surface and shelf of the sinker groove when the sinkers are moved radially inward to lower the needle cylinder end of each sinker and to raise the needle cylinder end of the sinker when the sinkers are moved radially outward. A guide is on the cam for engaging the sinker and guiding the sinker downwardly to engage the sinker step in the sinker ring well. A throat is on the sinker for engaging and holding the knitted fabric when the sinker is moved radially inward, the throat extending rearwardly and angularly relative to the sinker. In practicing the method of operating the apparatus the needle end of each sinker is raised as adjacent needles move downward and is lowered as adjacent needles move upward.
