Abstract: A cushion cam is provided in association with an adjustable stitch cam and is rendered adjustable with the stitch cam such that a constant gap is maintained between the stitch and cushion cams regardless of the position selected for the stitch cam.

Abstract: An improvement in multi-feed circular knitting machines wherein the knitting needles are adapted to assume knitting and non-knitting conditions and whereas the jacks are suspended in the knitting needles in an articulated manner. The cam clyinder is provided with a needle lowering cam at each cam system. Each jack has at least one butt adapted to be engaged by the needle lowering cam when the corresponding jack has been swivelled on to the cam cylinder. The improvement comprises the construction and the manner of interaction of the butts and the needle lowering cam. The butts are arranged on the swivellable jacks and are selectively adapted to be pivoted away from the cam cylinder by means of a special pivoting device in each system when the corresponding needle is to misknit, that is in advance of the needle lowering cam of the system and are adapted to be swivelled back to their original position by special means immediately after having passed the needle lowering cam.

Abstract: Mechanism for adjustably supporting needle cams on knitting machines, particularly on circular knitting machines. The mechanism provides simple means for adjusting the cams both in the direction of the knitting stroke of the needles in the slots of the needle cylinder, i.e. in the direction of height, and in the direction transverse to this knitting stroke in the horizontal plane along the periphery of the cam assembly frame plate, that is, in a lateral direction for the lateral adjustment of the cams and thus to eliminate the manufacturing deviations in the angular distribution of the knitting feeds. In accordance with the invention, the cam assembly is provided with a prismatic recess, in which there is mounted a block which is slidable laterally, that is, in a direction tangential to the needle cylinder, such lateral adjustment being provided by a spring and a screw with a conical end or by an eccentric pin.

Abstract: A lock for circular knitting machines. According to the invention, a lock or cam comprises a fixed lock element supporting or carrying cams defining the guide tracks for the knitting needle heels, causing the outgoing and re-entering movements of said needles; such cams are secured to a slider movable between extreme positions within a guide of said fixed lock element. The slider has a threaded portion engaging a first screw thread of a manually operable adjusting element for the slider stroke, which adjusting element is provided with a second screw thread in opposite direction to the former; this second screw thread screwing in a threaded seat of the fixed lock element, so that at a rotation of said adjusting element there would correspond an overall displacement of the cam carrying slider equal to the sum of the displacement of said slider relative to the adjusting element and of that of the latter relative to said fixed element.

Abstract: Improvements in or relating to the drive cam ring sets for the needles, cam followers and the like on circular knitting machines. The cams are divided into units, each of the cam units being formed on a discrete rigid plate. The individual plates having a plurality of cams thereon are in turn attachable on a rigid skirt surrounding the needle cylinder.

Abstract: A high speed continuous knitting machine wherein the cylinder has a substantially circular cam track for the needle butts having a substantially uniform slope and disposed at an oblique angle relative to the axis of the cylinder, and also including cam controlled axially moveable sliders disposed between the needles for assisting in castoff, which sliders are moved in a direction opposite to the direction of movement of the needles.
