Abstract: A circular knitting machine includes a needle cylinder rotating around a vertical axis and a sinker ring rotating with the needle cylinder. The needle cylinder has in its outer edge portion vertically controllable tip needles with needle hooks opened downwards as loop-forming elements, and for each tip needle, a surrounding sinker supporting the loop-formation is held movable in the radial direction on the sinker ring. Further, for each tip needle on the needle cylinder, a press sinker is kept on the sinker ring horizontally in radial direction, to close the hook tip of the tip needle by pressing the needle tip to the needle shaft. The press sinkers are each disposed on the sinker ring between two adjacent surrounding sinkers. The circular knitting machine allows needle wear to be reduced and a selection between weft knitting and warp knitting as loop-forming techniques is enabled in a single machine.

Abstract: A knitting machine having needles which are mounted to be longitudinally moveable and having needle cams (14) with a needle control curve (13) for moving the needles, the needle control curves (13), at least in the latch closure region (Z), having a withdrawal angle (?)?35°.

Abstract: A cam for a circular knitting machine has at least one cam groove formed in a cam surface to receive and guide a foot of a stitch-forming tool with which the cam is intended to operate. Additional recesses are formed in the cam surface to reduce the striking surface between the cam surface and a shank of the stitch-forming tool.
