Abstract
A method and apparatus for forming pile fabric where the pile loops are controlled during the knock-over action of the needles. The sinker ring mounted sinkers include separate pile and loop forming ledges. The base thread is fed into the throat of the sinker, and with the sinker positioned with their loop forming ledges between adjacent needle stems, the alternate raising different sets of needles to feeding positions and the subsequent retraction to a tuck on the latch position and the subsequent clearing of the pile threads from the loop forming ledges assures that in the knock-over action of the needles the pile loops remain under the control of the pile forming ledges.
