Abstract: A stitch-forming machine which has needles guided on a needle support for displacement in the longitudinal direction and controlled by needle cams and also has holding-down and knocking-over sinkers which are adapted for displacement between the needles in the region of their heads and are moved by sinker cams in the longitudinal and transverse directions relative to the needle support.
Abstract: The invention relates to an apparatus and a method for the production of textile surface configurations. The invention is on chain stitching or needle stitching machines for the production of clothing, decorative and household textiles, as well as for technical textiles. The object of the invention is achieved in that a flat guiding element has a contact edge on the side facing the fleece to be bound, and has at least one guiding hole or an eyelet or the kind for the guidance of the thread. The guiding element is movable and can have different shapes.

Abstract: To insure gentle latch operation, and particularly gentle opening of the latch, the last-knitted loop (36) is constrained to move in the same direction as the needles (2) by controlling movement of sinkers (7) in the same direction as the needles, at a speed slower than needle speed during the raising phase of the needles (FIGS. 5, 6), so that initial movement of the latch occurs slowly and not abruptly to permit faster knitting speeds by reducing stresses on the latch. Conversely, during closing movement of the latch (FIGS. 9, 10), initially, the loop and the needle are lowered simultaneously, the lowering speed of the loop, controlled by the sinker (7) being slower than the lowering speed of the needle. Cast-off can be improved by rapidly controlling the loop by suitable sinker movement (FIGS. 11, 12).
Abstract: To permit independent adjustment of movement of knock-over bit - jack sinker elements (3) having knock-over or casting-off heads (7), a cam box (22, 23) has an individually adjustable raising and lowering cam track (26, 28), engaging a butt (6) on the sinker element. The shaft (4) of the jack or sinker is formed as a double-arm lever (16, 17) with an intermediate fulcrum or pivot point projection (18), engaging a surface of the knitting machine, for example a cylinder groove, and two individual cam tracks (34, 35) are provided, formed on cam carriers (36, 37), of which, preferably, at least one (36) is adjustable, to provide for rocking movement of the knock-over bit - sinker jack element about the fulcrum or pivot projection independently of sliding longitudinal raising and lowering under control of the customarily provided cam structure (26, 28).
Abstract: In order to increase the operating speed of the knitting machine and to attain a fine needle cut, sinkers (7), with their shaft (12), are guided on a needle carrier (1), and simultaneously forming guide ribs for adjacent needle shafts (3). A projection cam (16) which imparts to the sinkers (7) the movement transverse to the needles (2) is disposed directly on the needle carrier (1).
Abstract: A circular warp knitting machine is designed for knitting hosiery pieces and comprises a stationary needle cylinder, knitting needles which are installed in grooves of two concentrically arranged annular guide bars, racking mechanisms for racking the guide bars together with the guide needles along the front of the knitting needles and rocking mechanisms for rocking the guide needles between the knitting needles. The needle cylinder accomodates a sleeve movable therealong which controls the movement of the sinkers. A holder movable along the needle cylinder is arranged inside the needle cylinder and carries the knitting needles mounted therein, and sliding frames of the rocking mechanisms of the guide needles and concentrically arranged rotatable casings carrying the annular guide bars are installed over the needle cylinder coaxially therewith. This arrangement ensures a simple and compact structure of the machine.

Abstract: A method for knitting a garment on a double-cylinder circular knitting machine, comprising the steps of withdrawing the stitch sinkers firstly with only the yarn taken up by the lower cylinder needles, subsequently lowering the upper cylinder needles to pick up the yarn while causing the stitch sinkers to outwardly project and to pick up the yarn taken by the upper cylinder needles, and raising the lower cylinder needles only after the sinkers have been withdrawn. There is also disclosed a double-cylinder circular knitting machine in which the cams for controlling the sinkers have a notch in a position substantially vertically below the lowering cam which controls lowering of the upper cylinder needles to take up the yarn, the notch being arranged before the raising cam controlling raising of the lower cylinder needles for taking up the yarn.
Abstract: An improved warp knitting machine employing compound needles and an interconnected trick-sinker mechanism which maintains a fixed relationship with the knitting needles and tends to hold the knitted fabric in line with the back guide bar to lessen the stress on the knitting needles.
Abstract: An apparatus for producing meshware, comprises a needle cylinder carrying a plurality of needles with sinkers therebetween, the needles and the sinkers both being movable so that one part of a stitch is made up by movement of the needles and the remainder of the stitch is made up by movement of the sinkers.The method of producing the meshware is also included.
Abstract: The pant or body portion of a pair of tights or panty hose is produced on a dual-cylinder knitting machine using oscillatory motion of the two cylinders. Subsequently the leg portions of the tights are produced using continuous motion of the two cylinders, one leg portion being formed within the other leg portion.
Abstract: The invention comprises an improved apparatus and method for producing knit fabrics having terry loops on both the technical front and technical back sides of a ground fabric in which the terry loops are interconnected or knitted jointly with the ground yarn into the base fabric and are thus securely held therein. Novel needle latch arresting elements and improved sinker designs eliminate severing of previously formed loops incorporated in the ground fabric.
