The Raschel machine is comprised of a plurality of lapping belts and a yarn laying-in comb which penetrates the pattern yarns running to the latch needles. The comb moves substantially at right angles to the axis of the latch needles and carries out a combined stroke and oscillating motion. In addition, a plurality of stitch forming systems are provided on the opposite side of the lapping belts and laying-in comb from the plane of the latch needles. The guide bars of these systems oscillate at an angle to the pattern yarns and move in a circular orbit.

Stationary spools located at one end of a warp knitting machine are coupled to thread providing means which in turn is coupled to a thread transfer means for carrying the weft threads across the full bed of the warp knitting machine. The weft thread providing means and the transfer means in addition to means for removing the weft threads from the transfer means are disposed within the volume delineated by the needle bed, push rod and guide bar drive levers of the knitting machine and are disposed a position between the forwardly and rearwardly disposed guide bars thereof.

There is provided a modified warp knitting machine for the production of netting from heat sealable synthetic fibers which comprises a source or warp threads, inlay sinkers for contacting the weft thread to the warp thread, and heat sealing means for sealing the warp threads and the weft threads together to provide the desired effect.

A sliding clasp fastener stringer is disclosed which comprises a warp-knit support tape carrying a row of interlocking fastener elements, said tape having a web portion of a relatively coarse interstice structure suitable for stitching the tape to an article of clothing, and a longitudinal edge portion formed solely by knit-loop forming threads suitable for mounting the row of fastener elements stably into position thereon against displacement relative to the tape. The web portion and the edge portion are interconnected transversely by a connecting portion which is formed by threads merging from both of said portions and which has a relatively fine interstice structure.

A warp knitting machine is adapted for the production of looped fabric by providing filler sinkers to supply filler threads extending over the entire width of the machine in parallel relationship. The filler threads arrive consecutively at the needle zone, and basic fabric and loops are produced simultaneously using warp threads and pile yarn, respectively. The filler sinkers perform a substantially rectangular movement ensuring a fail-safe operation with high operating speeds.

A warp knitting machine includes an improved thread feeding apparatus. The thread feeding apparatus includes a source of weft threads which are drawn through a plurality of flexible tubes and are connected in groups to a plurality of slideable blocks. The blocks are adapted to move sequentially in synchronization with a conventional weft thread transfer chain having standard weft thread pick-up clamps attached thereto. The invention allows a large number of threads to be fed to a conventional warp knitting machine at one time.
摘要:
In a warp knitting machine with devices for handling long weft threads and for feeding the threads to knitting tools of the machine and a guide bar carrying a plurality of eye needles having elongated shanks, at least one formed sinker carried by the guide bar and including a pair of tongue-like support members extending at predetermined mutual spacing substantially parallel to one another and substantially perpendicularly to the shank of at least one of the eye needles of the guide bar so as to support thereon weft threads fed to and extending along the knitting tools.

A warp knitting machine, particularly of the Raschel type, is provided with a device for inserting a weft thread into the knitted loops wherein a crank-shaped thread laying device is provided with a thread guide which is operable to undo the twist which occurs during the revolving movement of the thread laying device, thereby making it possible to draw, for example, two weft threads, which may be of different color or composition, simultaneously from the weft thread supply reels. A weft thread storer is provided which consists preferably of two storage discs facing each other and which is movable in the direction toward the knitting needles. The warp knitting machines can produce knitted goods whose appearance and properties correspond to those of woven goods, but where the knitted product can be manufactured at substantially higher production speeds than the woven product.
摘要:
A warp chain receives yarn from a plurality of spools fixedly arranged laterally adjacent a warp knitting machine. The yarn is transferred from the spools to the chain by a plurality of pivotal yarn guides whose free ends pass through arcuate paths during pivoting of the guides. One point of each yarn guide path is adjacent the warp chain for transfer of the yarn thereto and all the arcuate paths intersect at least in one point in the region of the yarn transfer point.

Apparatus for inserting bunches of weft threads into a weft thread storage device in a warp knitting machine includes means for making the weft threads ready, and a weft thread drawing-off device including a suction nozzle displaceable over the width of a fabric web being warp knitted by the machine, and means for actuating the suction nozzle to align the ends of the weft threads made ready by the readying means and to seize the weft thread ends as well as draw off the seized weft threads and insert them into the weft thread storage device.
