ABSTRACT:
A pile patterning mechanism for a circular knitting machine comprises: a sinker bed provided with a plurality of radial, horizontal grooves and disposed on the outer circumference of an upper end of a needle cylinder; a plurality of pile sinkers fitted in the radial, horizontal grooves of the sinker bed so as to be slidable and tiltable. A plurality of horizontal pile jacks each having a plurality of butts are fitted in the radial, horizontal grooves of the sinker bed on the radially outer side of the pile sinkers so as to be slidable and tiltable; and a control unit is provided for controlling the pile sinkers and the pile jacks to slide and tilt the pile jacks and the pile sinkers. The control unit includes a plurality of sinker cams, a jack selecting device provided with a plurality of actuators, and jack cams. The horizontal arrangement of the pile jacks ebables the pile jacks to exert a reliable action on the pile sinker. A knitted article has at least a pile stitch portion of an optional pattern formed by the reciprocating turning operation of a needle cylinder. Pile loops can be formed on optional wales by the reciprocating turning operation of the needle cylinder regardless of the needle loop forming operations of the needles.
