ABSTRACT:
A knitting machine capable of forming filaments of yarn, thread, and the like into a loop-in-loop arrangement includes a plurality of rotary needles which are axially spaced for rotation about a common axis and have at least two circumferentially spaced hook portions. As a needle is rotated, a hook captures a segment of filament being fed to the vicinity of the needle and pulls it into a loop. Upon further rotation, the circumferentially adjacent hook captures another segment of filament and pulls it into a loop through the previously formed loop which is still carried by the needle. As the needle continues to rotate, the first formed loop is cast off the needle by slipping out of the hook in which it is captured and this hook captures another segment of filament to start another cycle. The needles are rotated by an external drive means which either engages the needle periphery outside the loop catching and forming area or electrically couples the needles so they are rotated about their own central axis without an encumbering mechanical axis.
