The circular knitting machine contains a needle cylinder (1) with knitting needles (2), a sinker ring (15) which is rotatable about an axis of rotation jointly with the needle cylinder (1) and has sinkers (16), a stationary cylinder cam and sinker cam means which is associated with the knitting needles and sinkers, respectively, yarn and fiber feed units, an air guiding unit (45) provided with at least one suction nozzle and/or blowing nozzle, and a control cam (85) for acting upon the inserted fiber tufts.

Abstract: The present invention relates to improved pile fabrics containing courses in which at least two pile forming yarns are meshed across a complete course together cooperatively in various fabric constructions, and respectively into a ground fabric, and forming pile loops one another alternatively in succeeding wales or areas. The fabric is manufactured according to a process in which needles are moved into a feeding position in which they remain, meanwhile in at least two succeeding sections, alternatively, pile elements are selected and raised and after the feeding of a pile yarn are retracted to an intermediate position. The pile yarns are controlled separately from one another and are unaffected in their movement to the loop-forming and meshing action.

Abstract: The main object of the invention is to obtain knitwork the density of which is not influenced by the tension of the previously formed loops (15). In the particular case of terry cloth the terries are hence particularly uniform and stable.This is achieved by operationally interposing the terry sinker (2) between two stitch sinkers (3, 21).The method for producing terry knitwork is as follows:the first yarn (12) passes under the stitch hooks (7) while resting on the knocking-over surfaces (8) of the stitch sinkers (3, 21), and then over the terry hook (4) while resting on the terry surface (5) of the terry sinker (2);the second yarn (13) follows the first yarn (12), but instead of passing over the terry hook (4) passes along the working surface (6) of the terry sinker (2).The method for producing wide-mesh knitwork comprises for both yarns (12, 13) a path identical to that of the first yarn (12) of the terry knitwork production method.

The invention improves fabric quality especially when using cotton thread to form plush loops by providing beside the sinker to form plush and plain loops, an auxiliary sinker with a nib to tighten the ready plush loops and with a notch to hold and to pull-down the plush loops from the sinker to form plush and plain loops.

Abstract: Patterned pile (terry or plush) fabrics are made on circular knitting machines with cylinder and sinker ring or latch needles and pile elements (pile sinkers, pile hooks, latch needles). The pile elements are not selected, but perform their pile forming motions every knitting cycle. The latch needles of the cylinder are, however, selected both for knitting desired structures in the ground or base fabric and for forming the pile loops in the desired pile regions. The needles selected to form pile loops engage the pile thread fed at a higher level than the ground thread, which is fed at a level such that it is not affected by the pile elements, e.g. below the webs of pile sinkers. The ground thread is held in non-pile forming needles with their hooks at the level of the pile elements while the pile thread is fed to further extended needles which are then retracted to the same level as the needles holding the ground thread before all the needles are retracted to the knock-over position.

Abstract: The invention relates to circular weft knitting and according to the method described, those stitches which are formed between a cylinder needle and a dial needle are formed around a guide member which lies in the angle between the verges of the cylinder and the dial, these stitches sliding off one end of the guide member. The guide member lies in at least that region of the machine where the needles begin to lift, and preferably extends beyond the position at which the needles slip the loops so that the stitches formed between the cylinder needles and the dial needles are completely formed over the guide member.The invention is particularly useful for controlling the insertion of a lay-in effect yarn, since the guide member provides a containing effect which restricts movement of the lay-in yarn out of the mouth between the stitches already formed on the cylinder needles, and those about to be formed on the dial needles. It is possible to use lay-in yarns of large diameter.

Abstract: In a circular-knit, closed end tubular article, for example, a stocking or a sock, the opposite-lying loops of the linking course at the closing end are successively embraced by a linking thread and are drawn thereby together until their complete closure is aligned, thus forming a linear seam, the end of such articles being closed by laying of the linking thread in selected needles which are alternately operated on the opposite sides of a cylinder; as the thread is being pulled out, it brings together the opposite-lying loops of the linking course until their complete closure is aligned to form the linear seam which is scarcely visible on the article and its appearance resembles a looping seam.

Abstract: The present invention relates to a method of producing pile or plush goods or fabrics on circular knitting machines with plush hooks in the cylinder and latch needles in the dial and circular double knitting machines by means of pile hooks in a needle bed. Certain selected pile hooks are raised prior to the needles in order to prevent the fabric from raising with the needles while the pile hooks which are not selected for the formation of pile loops are retracted prior to the feeding of the pile yarn. Subsequent to the formation of the pile loops, the pile hooks are advanced into the loop forming position by the stitch cam until the needles move into an inactive position after the stitch formation, in order that the stitches are relieved (from tension) and withdrawn from the dial.

Abstract: An inlay or plaiting yarn is passed through knit stitches of a plain knitted fabric, the plaiting yarn is wrapped around the side portions of the knit stitches of the base fabric by a needle having a main latch and an auxiliary, angled latch, is knocked off over the tip end of the needle while the stitch of the main fabric is caught in the hook thereof, the plaiting yarn being pulled down by sinkers to pull the plaiting yarn tight about the lateral sides of the base knit fabric to form loop piles, and cut, if desired, to form cut pile fabric.

Abstract: A knitted fabric formed on a knitting machine includes longitudinal and transverse weft yarns incorporated into the fabric during knitting. A further transverse weft yarn is incorporated into the fabric and is interlinked with the courses of stitches of the fabric. Part of this further yarn, as determined by the needle selection, is visible on a surface of the fabric and serves to provide a pattern effect.

Abstract: Plush fabrics are produced on a conventional double jersey knitting machine by feeding a plush yarn to conventional cylinder and dial latch needles and feeding a ground yarn to the dial needles only, whereby long loops are formed in the plush yarn and short loops in the ground yarn; and thereafter causing the cylinder needles to execute a knitting movement without feeding yarn thereto, whereby the long loops are released from the cylinder needles to form the plush pile and cylinder needles are freed for a repetition of the knitting cycle. Some of the conventional feeders on the basic machine are replaced by auxiliary feeders designed to feed yarn to the dial needles only, others may be simply omitted in order to provide for the release of formed loops from the cylinder needles, while others are replaced by ancillary devices to clear released loops from the knitting zone and to open the latches of the cylinder needles for a fresh knitting cycle.

Abstract: A flat bed or circular knitting machine has an additional bed which accommodates in grooves or tricks pairs of yarn-guide members which are controlled alternatively by cams to co-operate with needles of the machine. The ends of each yarn-guide member carries a hook which co-operates with an eyelet to effect the actual guiding function.

Abstract: An improved circular weft knitting machine is of the type that directs warp insert elements inwardly and outwardly of the needle row in coordination with alternating interior and exterior knitting feed stations. The warp insert element is thereby woven to extend along the inside of the knitted fabric at an exteriorly feed knitting course and along the outside of the knitted fabric at an interiorly feed knitting course. The improvement includes a weft insert element feed station to locate a weft insert element between the inside surface of the knitted fabric and the outside surface of the warp insert elements. The weft insert element is supplied by a spool mounted outside of the needle row to a feed tube which discharges inside of the needle row at a point after an external knitting feed station and prior to the next interior knitting feed station.
