Abstract: A machine for producing stitch bonded fabrics comprising means for supplying a layer of warp threads, means for continuously supplying a weft thread, means for supplying a plurality of stitching threads and means for stitching the warp layer and weft thread together with said stitching threads, the improvement being that the means for supplying and laying the weft thread consists of a pair of closely spaced plates, means for forwarding an individual thread towards the plates and means for imparting an oscillatory motion to the forwarded thread before it passes between the plates.

Abstract: 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.

Abstract: The invention relates to a device for producing weft webs consisting of parallel spaced threads, in which at least one weft thread is fed around positioning, holding and advancing elements which consist of continuous endless belts which support a plurality of juxtaposed blocks which have a length corresponding substantially to the desired spacing between two consecutive weft threads. The blocks are in contact with one another in the rectilinear portions of the endless belt and spaced in the curved portion as they pass around drive rollers. At least one reciprocating thread guide has a free end which passes between the blocks in the curved portion of each endless belt, to feed thread between the blocks.

Abstract: A plurality of weft threads provided by stationary spools located at one side of a warp knitting machine are picked up by a thread transmission means and are presented to the needle bed of a warp knitting machine. The weft inserting apparatus is disposed within the space included by the needle bed, push rod and guide bar drive levers of the knitting machine.

Abstract: A weft thread tensioning device for use on a warp knitting machine provides a means for testing the tension of the weft threads and, if the threads are not at the desired tension, tensioning the threads to a predetermined amount. The device includes a spring loaded lever and U-shaped bracket which adjust the tension on the weft thread just prior to insertion into the bed of the knitting machine.

Abstract: A restrained web of orthogonal strands is formed by first traversing the strands according to the disclosure of U.S. Pat. No. 4,016,631 in a diagonal pattern with V-shaped reversals between two rows of strand-restraining elements along the selvedge of the web and then converting the diagonal pattern to an orthogonal pattern by forming an extended loop in each strand along the selvedge.

Abstract: Apparatus for feeding yarn, sliver or fibrous materials wound on stationary supply packages to a texile machine, comprising a plurality of movable material transporting elements and a plurality of movable material laying-in elements for feeding the materials from the supply packages to the textile machine, endless tracks defining working and return sections for said transporting elements and working and return regions for said laying-in elements, said transporting elements and said laying-in elements running in series on said endless tracks, and entwining of the materials during successive runs of said elements on said tracks is avoided by at least one deflection element by means of which the materials are fed via said transporting elements to said laying-in elements, during successive runs thereof through the working region, alternately from one and another side of a surface laid through the working region of said laying-in elements and the return section of said transporting elements.

Abstract: A knitting machine has a weft thread laying unit for laying weft threads for linking with warp threads by means of needles, comprising a guide bar extending across the machine, and a slider slidable along the bar, the slider having a weft thread guide to lay a weft thread in front of the row of needles. The unit may have at least one pair of oppositely movable sliders to reduce inertia force in the unit.

Abstract: First and second spaced apart conveyors, extending toward the knitting instrumentalities of a knitting machine, each carry a plurality of thread clamping means. Guide means bring filling threads from filling thread supplies to the first conveyor where they are clamped. The guide means then moves to the second conveyor to pull filling threads from the supplies and draw them between the conveyors, the filling threads being clamped in the second conveyor. Each thread clamping means carried by each conveyor includes a pair of pivoted clamping members and resilient means urging them to a closed condition. An actuating cam engages the clamping members to open them for receiving a filling thread from the guide means. Funnel-like members are carried by the guide means for directing threads into the clamping means. A single locking bar carried by the guide means locks all filling threads against further withdrawal from the supplies after the threads are clamped in the second conveyor.

Abstract: 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.

Abstract: In a fabric constituted lengthwise of stitched warp threads and, transverse thereto, an array of weft threads substantially parallel to one another, the array of weft threads is in the form of repeating sections, each section comprises a plurality of discrete portions of weft threads and each discrete portion extends in a continuous line at least twice from one lateral border of the fabric to the other lateral border of the fabric and forms a U at at least one of the borders of the fabric. This fabric is made by a method and with an apparatus in which the weft threads are transferred to two feeding means which transport the weft threads to a zone in which warp threads are stitched into the array of weft threads, the transferring being effected by a weft layer which moves between the feeding means transversely to the direction of motion of the feeding means and, at selected intervals, parallel to the direction of motion of the feeding means.

Abstract: A knit fabric is provided in which warp knit stitch chains are formed at spaces between inlaid warp ends and have loops thereof sinuously interlaced with filling ends laid at opposite sides of the warp ends so that the filling ends are held against the warp ends and both warp and filling ends are caused to interact in a manner producing an appearance approaching that of a woven structure. The method of forming this fabric and means for doing so are also disclosed.
