ABSTRACT:
A process and apparatus for producing knitted cut-pile fabric on a conventional circular knitting machine having a cylinder containing conventional latch needles and a dial containing dial elements each having a hook, a yarn cutting edge spaced from the hook and a yarn supporting surface extending therebetween, each dial element being radially movable between adjacent cylinder needles. Body yarn is progressively fed to the cylinder needles and pile yarn is progressively fed to the needles and the dial elements, the needles and dial elements being manipulated to form stitches of body yarn on the needles, to associate the pile yarn in the stitches and form pile loops on the dial elements, and to cast-off the needles the associated stitches and pile yarn to anchor the pile yarn in the stitches. The pile loops are retained and distended on the dial elements with their hooks and, subsequent to the casting off of the associated stitches and pile yarn, the dial elements are manipulated to advance their cutting edges against the retained pile loops, thereby cutting the pile loops to form cut-pile ends. A presser bar is provided for clamping the retained pile loops against the outer circumferential surface of the dial during the cutting thereof by the dial elements. A guide wire is also provided to guide the cut pile ends progressively radially inwardly of the cylinder after the cutting thereof. A fabric may be produced having alternate courses formed in loops in alternate wales and float stitches across intermediate wales, and intermediate courses formed in loops in intermediate wales and float stitches across alternate wales with cut ends of the pile loop forming yarn projecting from the fabric face from each side of each alternate and intermediate course loop.
