Abstract: A wrap feeding device for a circular knitting machine comprising a support ring and a yarn guide mounted on the support ring and pivotally movable in a horizontal plane, the yarn guide having a front end extension extending outwardly from the support ring over the head of the vertical needle and forming a hole in its front end through which the yarn passes. A cylinder is disposed beneath the support ring concentrically therewith, and a return spring is connected with the yarn guide so as to normally retain the yarn guide in a position deflected toward a direction of rotation of the cylinder. An abutment is disposed in a path of movement of the front end extension of the yarn guide for contacting the yarn guide to cause the yarn guide to return against the return spring and to lap a wrap yarn thereon around the vertical needle over the front half circumference thereof.

Abstract: A pattern-yarn feed device in a knitting machine in which a needle-cylinder has a plurality of circumferentially-spaced, vertical slots in its periphery and receives vertically-slidable needles; a rotary cylinder above the needle-cylinder and a guide cylinder surrounding and secured by the rotary cylinder and having circumferentially-spaced vertical slots; a cam member surrounding and opposing the guide cylinder and including rest and pattern-yarn-feed cams; a vertical-guide piece received in each slot in the guide cylinder and engaging the cam member for vertical reciprocation as the guide cylinder rotates, the guide-piece having a guide slot at its lower end; a twisted rod unit guided in the guide slot in the guide-piece and rotatable as the guide-piece rotates; and a horizontal guide arm secured to the lower end of the twisted rod unit and having a pattern-yarn-guide hole rotatable as the twisted rod unit rotates and a pattern-yarn is guided through said guide hole in the guide arm into one or more knittin

Abstract: A pattern forming device in a knitting machine comprising a framework, a needle cylinder journaled in said framework and having a plurality of vertical slots in its periphery, knitting needles slidably received in said slots for vertical movement, a rotary cylinder journalled in said framework above said needle cylinder, a pattern yarn guide cylinder secured to said rotary cylinder for rotation therewith and having a plurality of vertical slots in its periphery, pattern yarn guide pieces received in said slots in the guide cylinder for vertical movement and having notches, a cam member secured to said framework and received in said notches, said cam member having rest and yarn feed cams arranged in its periphery said guide pieces having slots at the lower ends, a twisted piece loosely received in the slot of each pattern yarn guide piece and having a threaded rod integrally formed therewith and a pattern yarn guide arm connected to the lower end of said threaded rod and having a pattern yarn hole for threadin
