A warp knitted fabric employs a warp knitted pattern as the ground stitches. In this novel fabric there are reinforcing threads of a substantially rigid material. The weft threads may run parallel to each other and are located between the needle loops of stitch rows that follow each other sequentially in the warping direction. Additionally, there are two sets of diagonal threads both of which run alternatively: (a) between two needle loops of neighboring wales and (b) between two needle loops of successive stitch rows. Laid-in warp threads may be provided between needle loops of adjacent wales. There is thus provided a fabric having higher rigidity in all directions.

A warp knitting machine using warp and weft threads produces a fabric with a woven appearance on one side. The machine has at least one forward thread system for forming stitches and at least one rearward thread system for forming stitches. This rearward thread system is successively operable to reciprocally form a common stitch with a corresponding pair of the warp threads of the forward thread system. A weft thread magazine can repetitively place weft threads between the forward and rearward thread system. The forward thread system is successively operable to reciprocally lay a portion of each of its warp threads at one of two corresponding, alternate wales over at least one of the weft threads. The rearward thread system is operable to lay its warp threads behind the weft threads. Before making a stitch, the forward thread system performs at least one overlap of at least two needle spaces while the rearward thread system is displaced to reciprocally lay its warp thread about needles onto which adjacent warp threads of the forward thread system are laid.

A process for the manufacture of contoured pile ware on a conventional double needle bar warp knitting machine yields textured pile fabric with an unusual appearance. The pattern is formed of pile threads of different length and in different positions in the pile ribs and are bound together with the base fabric. The ware is formed on a twin bed warp knitting machine and subsequently is cut to form two individual panels.

A weft thread magazine for a warp knitting machine has two endless transfer chains. The chains have holders for retaining weft threads in parallel and presenting them to a needle bed. Also included is a thread laying arrangement which transports the weft threads from one transfer chain to the other, and which is provided with a comb arrangement. The comb arrangement includes a comb element having at least one combing peg which is introduced between the weft threads proximate to one of the transfer chains and which moves parallel to the weft threads and is removed proximate to the other transfer chain. A carriage has a thread guide for guiding at least one weft thread into a position parallel to a previously laid weft thread. The comb element is carried on the end of the carriage directed toward the needle bed.

The invention is directed to a warp knitting machine having a weft thread insertion arrangement comprising two parallel transfer devices which carry the weft threads in holders having a predetermined separation from each other and which are driveable in the direction of the needle bed. Also included is a reciprocally moveable weft sled arrangement carrying thread guides to lay mutually crossing layers of diagonal weft threads that subtend mutually opposed angles to the stitch rows. The guides place the threads into the weft thread holders first in one of said transfer devices and then in the other transfer device in exact and predetermined separations. The invention is further directed to a novel fabric having inlaid weft and warp inlay threads.

The process for preparing high density pile ware on a warp knitting machine wherein the pile loops formed from at least one thread system are knotted in by the stitches of the ground fabric structure formed from at least one other thread system includes at least one elastic thread. The high density pile ware includes an elastic thread having an elongation of at least fifty percent which may be woven into the ware or be utilized as an inlay, weft or straight inlay thread, thereby retaining the adjacent stitch wales and/or stitch rows in compression.

A warp knitting machine having at least two guide bars, a needle bar, and a cooperating driving means utilizes a plurality of slider needles affixed to the needle bar and in combination with a trick plate member disposed between the guide bars in front of the needles is adapted to interact with the fall plate threads and the needles, to provide a trick plate weft thread lay in bound by the ground thread without the fall plate thread forming a stitch.

A displacing means is used to move at least one guide bar by at least one needle space in order to remove the loops on a terry cloth towel material such as knitted on a warp knitting machine. The displacing device basically comprises a transfer means for driving a second pattern gear wheel from a conventional first set of gear wheels, a cam follower arrangement operatively associated with the second set of pattern chains; a clutch means actuated by the cam follower mechanism, another cam actuated by the clutch and a cam follower and linkage mechanism associated with the clutch cam for moving the guide bar in the direction of its normal motion by at least one additional needle space. The transfer means comprises first and second coaxially mounted gears which are driven by an idler gear mounted near the periphery of the circumference of the first set of pattern chain wheel. In this manner a considerable reduction of speed is obtained between the first set of pattern cam wheels and the second set of pattern cam wheels. The clutch mechanism is spring-loaded and includes a Z-shaped lever which will engage an internal tab in response to release of the clutch by a pawl mechanism. The method and apparatus of the present invention makes it possible to knit towels having transverse strings which are useful both decoratively and for defining the area in which the cloth is cut into individual towels with pattern chains considerably shorter than those used in the prior art and also allows those towels to be knitted without altering the basic thread consumption rate.

An article and process for the formation and molding of articles such as gaskets from useful areas of a flat textile panel. This panel is divisible into useful areas possessing textile reinforcement inlay threads in greater thickness and density than in the majority of the areas of the panel remaining outside the useful areas. The textile panel is produced from a ground pattern with the reinforcement threads inlaid thereinto. The useful areas are separated from the textile panel and embedding material is embedded onto the appropriate useful areas corresponding to the articles before or after the separation of the articles.

A weft thread magazine operates in a warp knitting machine having a needle bed. This magazine includes a pair of endless transfer chains, each having a plurality of holders for retaining weft threads in parallel and for delivering them to the needle bed. Also included is a thread laying arrangement operable to transversely reciprocate between the transfer chains and to transport weft threads from one chain to the other. The arrangement also includes a carriage having a plurality of thread guides for transferring weft threads around the holders as the thread laying arrangement reverses direction. These thread guides can reciprocate between an operative and inoperative position. In the inoperative position, the thread guides are precluded from transferring thread to the holders. The magazine also includes a control device for moving the thread guides between the operative and inoperative position.
