Abstract: A circular hosiery knitting machine of the seamless type, comprising a supporting structure and a needle cylinder provided with a plurality of axial slots, each of which accommodates a needle which can be actuated with a reciprocating motion along the corresponding axial slot; a sinker ring being arranged around the upper end of the needle cylinder being provided with a plurality of radial slots, each of which accommodates a sinker, which can move with a reciprocating motion along the corresponding radial slot, each sinker being provided with a heel which protrudes upward from the corresponding radial slot and can engage at least one path defined in a sinker cover which faces in an upper region the sinker ring, the needle cylinder being actuatable with a rotary motion about its own axis with respect to the supporting structure and to the sinker cover.

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 circular knitting machine for men's socks comprises a cylinder, cylinder needles, movement devices of the cylinder needles, sinkers (12), movement devices of the sinkers, a dial (14), a dial shaft, dial needles (18) mechanisms for moving the dial needles, selector mechanism able to selectively move the dial needles, a yarn-finger, dial needle selector mechanisms. The dial needle selector mechanisms comprise selector rods (30) limited in both directions radially to the respective dial needles.

Abstract: A method for knitting manufactured articles with circular knitting machines, particularly high-fineness circular knitting machines, which consists in that at least once during the formation of the manufactured article the number of active needles is reduced by transferring the last loop of knitting formed by certain needles to contiguous needles and thus excluding from knitting the needles that have transferred the loop of knitting during the formation of at least one subsequent row of knitting by the other needles that are kept active. This provides a manufactured article which has regions knitted with a certain number of needles and regions knitted with a smaller number of needles, obtaining particular transparency or shaping effects on the manufacture.

Abstract: A cam mechanism and method in a circular knitting machine having at least two types of knitting needles each having a master butt and at least two selector butts and including a stitch cam for engaging the master butts and retracting the needles from the knitting and tucking positions to the stitch-forming level, and knitting, tucking and welt-guarding cams movable between extended operative positions and retracted inoperative positions, and a selection device for individually selecting and moving the knitting, tucking and welt-guarding cams between the operative and inoperative positions.

Abstract: An interlock circular knitting machine for knitting a double-knit fabric in which multiple yarns are knit into cylinder needle and dial needle wales, by two types of cylinder needles and two types of dial needles supplied by yarn carriers with multiple yarns, and controlled by a needle selecting cam system through first and second processes which cause the needles to move between high-tucking, holding, clearing and welt positions so that two yarns are knit together into stitch loops in each wale, the stitch loops in adjacent wales in each course being knit of one yarn from the stitch loop in the adjacent wale in the same course and a yarn from a stitch loop in the adjacent wale from an adjacent course.

Abstract: A rib jacquard knitting machine including dial needles arranged on the dial, cylinder needles arranged on the needle cylinder to knit loops with the dial needles, transfer needles and pelerine needles respectively arranged on the needle cylinder to make transfer stitches and eyelet stitches. A knit selector selectively drives the pelerine needles and the transfer needles into operative positions.

Abstract: Each feed of the multiple feed circular knitting machine is provided with selector cams to position needles in one of four positions, knit, tuck, welt and early withdrawal positions. Two types of knitting needles are provided and each type of needle includes a master butt with a knite selector butt and a tuck selector butt. The selector cams are mounted on rotatable selector cam cylinders which are positioned to overlap each other to permit the selector cams to be arranged at the closest possible lateral distance from each other and to thereby permit an increased number of feeds to be positioned around the machine. The early withdrawal position of the selector cams is provided so that the dial needles do not interfere with the formation of stitch loops by the cylinder needles, when knitting on only the cylinder needles, such as when forming blister knit stitch constructions.

Abstract: Weft double knitted fabric has a looped structure with some knitted loops drawn in one direction and other knitted loops drawn in an opposite direction. Yarns of some courses are drawn into knitted loops in both directions to form knit stitches on both faces of the fabric. Yarns of other courses are drawn into knitted loops in a first direction only to form knit stitches on one face only of the fabric. Yarns of still other courses are drawn into knitted loops in the second direction only to form knitted stitches on the other face only of the fabric. An inlay yarn is formed exclusively into tuck stitches extending in both directions, with different yarns drawn through the tuck stitches to form knit stitches on opposite faces of the fabric.

Abstract: The circular knitting machine comprises at least one sinking cam and one movable cam enabling a selection of knitting elements to occupy several positions. The sinking cam is rotatably biased into a working position in which its working ramp cooperates with the butts of the knitting elements selected for knitting and can be moved to a rest position in which the working ramp cooperates with the knitting elements which are welting. The sinking cam is held in its rest position by a surface thereon which engageingly cooperates with a locking means on the movable cam when the movable cam is in a position to cause the knitting elements to welt.

Abstract: A cylinder and dial type circular knitting machine not operable in interlock gating because of interference between cylinder and dial needles is provided with needles and needle controlling camming enabling the machine to produce interlock fabric in interlock gating.
