Abstract: In a knitting machine, a plurality of stepping motors (10) is controlled by an electronic control unit (35) and each motor transmits horizontal oscillations to a tube bar (5). Each oscillation is built up of a plurality of horizontal-movement steps, each step being delimited between two limit points to which a centered positioning of the threading tubes (8) in the spaces defined between the needles (9) corresponds. A photoelectric sensor interlocked to the control unit detects the passage before a given read point of optical locators reproduced on plate-like elements, each associated with the drive shaft of one of the motors, in order to check whether the individual bars perform correct movements. Should a cutoff in the electric supply to the knitting machine (4) occur, each tube bar (5) would be stopped at anyone of the limit points.

Abstract: An improved male-female type connector assembly. A male connector includes hook elements while a female connector includes a composite of a flexible substrate having a knit structure with loops produced about at least a portion of same. Loop weight, loop density and/or configuration of the hook elements may be varied to produce an assembly that is intended for repetitive connective, disconnect operations, or a semi-permanent structural connection.

Abstract: A stitch bonded fabric including a fiber fleece having a plurality of columns of warp-wise stitches, adjacent rows of the warp-wise stitches being offset so that bundles of fiber from the fleece captured thereby follow a sinusoidal path across the width of the fabric. A method of producing the stitch bonded fabric is also disclosed and claimed herein.

Abstract: A composite sheet material which is particularly useful as a backing material for carpet underlay is a stitched crepe paper sheet 5 with rows of apparent projections 13 formed therein between parallel rows of stitches 10 by deforming the crepe paper sheet without puncturing the paper. The stitches 10 substantially restrict the extensibility of the crepe paper sheet 5 and the apparent projections 13 are formed at a position in the crepe paper sheet 5 directly in line with the ends 11 of the stitches 10. According to the preferred method, each apparent projection 13 is in reality a depression between two projections formed in the opposite surface of the crepe paper sheet without puncturing the paper. In an alternative embodiment there is a pair of apparent projections 13 formed in the crepe paper sheet 5 between adjacent rows of stitches 10.

Abstract: A method and apparatus for the production of a textile strip, by preparing and aftertreating an intermediate product, with the product textile strip being a new article of manufacture and having long weft elements, especially long weft threads, provided diagonally to the strip length, intersecting one another, and connected by longitudinal rows of stitches. The apparatus includes a device on a warp knitting machine, particularly a thread knitting machine, having at least one movable weft laying device, in order to work long weft elements or weft threads, which extend over the entire working width, into the textile strip.

Abstract: A weft insertion warp knit fabric having a terry or boucle effect is produced by overfeeding at least some of the wrap yarns to a conventional weft inserted warp knitting machine, such as a Raschel, (e.g.) Liba, or Mayer. Terry loops extend outwardly from the technical back side of the fabric, and the loops may be continuous over the entire fabric face, or discontinuous, i.e. being disposed in an intermittent pattern. A substrate may be provided to which the warp and weft yarns are stitch bonded, or the fabric may be substrate-free. By varying the knitting yarn denier and/or stitch length, the erectness of the terry loops may also be varied. The fabric is especially suitable for draperies and upholstery.

Abstract: Aesthetic warp-knit, weft-inserted fabrics are produced having multiple substrate layers, warp yarns extending in the warp-wise direction of the fabric, and weft yarns extending in the weft-wise direction of the fabric. The warp and/or weft yarns are interposed between the multiple substrate layers. Warp stitching yarns forming stitch wales spaced-apart along the warp-wise direction of the fabric and stitched through the substrate layers hold the warp and weft yarns in position relative to one another and relative to the substrates. The substrates may also be provided in juxtaposed relationship to one another so as to increase the opacity, esthetics, and dimensional stability of the resulting fabric. Thermoplastic fibers may be incorporated in the fabric such that upon plasticization and subsequent cooling, they assist in binding of the resulting fabric.

Abstract: The weft threads (10) are clamped in weft thread hooks (12) supported on longitudinal conveyors (43, 44) extending perpendicular to and adjacent opposite ends of a row of knitting needles (42) by means of clamping slides (20) mounted on the longitudinal conveyors (43, 44). The clamping slides (20) are supported for sliding movement in a perpendicular direction relative to the movement of the longitudinal conveyors (43, 44) and are movable between an inactive, retracted position away from the hooks (12) through a placement zone (E) and an active position pressed against the hooks (12) and the weft threads (10) as the longitudinal conveyors (43, 44) move through a clamping zone (K) extending both upstream and downstream of the row of knitting needles (42).

Abstract: An improved male-female type connector assembly. A male connector includes hook elements while a female connector includes a composite of a flexible substrate having a knit structure with loops produced about at least a portion of same. Loop height, loop density and/or configuration of the hook elements may be varied to produce an assembly that is intended for repetitive connective, disconnect operations, or a semi-permanent structural connection.

Abstract: In a method of producing composite sheet material by forming longitudinal rows of stitches 7 in a paper sheet material 1, the length of paper sheet material 1 used per stitch 7 is increased so that there is entrapped within each stitch 7 in each longitudinal row of stitches 7 a portion of paper sheet material 1 having a length greater than the length of the completed stitch 7. In consequence there are formed in the composite sheet material a longitudinal series of laterally extending corrugations, ridges or ribs which, in the case of a crepe paper sheet material 22, constitute a gross crimp imposed without distortion of the crimps in the initial crepe paper sheet material 22.

Abstract: This invention relates to a stitch-bonding warp knitting machine and a process for operating it. The stitch-bonding warp knitting machine comprises a plurality of knitting needles that pierce a continuously conveyed band of material. The knitting needles are driven by two different reciprocating motions, one of which reciprocates the needles along their longitudinal axis and the other of which swivels said knitting needles about an axis. The invention also includes means for continuously conveying a band of material through a point in the path of said reciprocating knitting needles. The reciprocating action of the needles and the swivelling action about an axis remote from the point that said band of material passes is such that said knitting needles pierce said band of material and at the same time move in a transverse direction in the direction that said band of material is moving and at the same speed of movement all of the time that said needles are penetrating through said band of material.

Abstract: A flat-weft knitting machine for producing a weft-and-warp-knit fabric, e.g., a stitch knitting machine, employs a weft yarn insertion device, which moves backward and forward, for constantly guiding a continuous thread or yarn group. The insertion device transfers one weft yarn group of the yarn group to first and second weft yarn conveyor means. The weft yarn group is then separated from the insertion device and the yarn group. The weft yarn group thus has free ends at both ends and is then conveyed by the weft yarn conveyor means to a looping point, for connection with loop-forming warp yarns to form a fabric.

Abstract: A structural fabric (20, 28, 40, 48) and a method for making the same is disclosed. Structural fabric (20) is comprised of a plurality of substantially parallel, uniaxial structural yarn (22) and a secondary yarn (24) for holding the structural yarns (22) in place. The structural yarns (22) are oriented at an angle skewed from both the fabric centerline (26) and a line perpendicular to the fabric centerline (26).A double biased fabric (28) is made by sewing two fabrics (20) together with secondary yarn (39). An alternate double bias fabric (40) is made by sewing together with secondary yarn (46) the two layers of a flattened helix made from structural yarn (42, 44) running spirally substantially the length of the fabric (40).A triaxial fabric (48) is made by sewing together with a secondary yarn (56) two single biased fabrics (50, 52) and a layer of longitudinally-extending structural yarn pieces (54).

Abstract: The present invention is directed to a warp stitching machine comprising a means for guiding a warp element onto a base material on which the warp element is to be formed into a warp of stitches. This guiding means for the chain element is situated on a bracing means in the warp stitching machine, and is preferably in the form of oblique channels for directing the warp element onto the base material.

Abstract: A weft thread laying apparatus for warp knitting machines includes a carriage having a plurality of thread guides disposed thereon perpendicular to a pair of endless transfer chains which carry the weft threads from a pickup area to a delivery area proximate the needed bed of the machine. The transfer chains are additionally accelerated in the pick-up area when the carriage, moving transversely to the chains, is on the outer side of the transfer chains, thereby permitting thread guides to lay thread around holding elements disposed on the transfer chains without requiring the carriage to move in more than one plane. The carriage is provided with a plurality of thread guides which have a skirt portion larger than its stem portion to insure that the threads do not become entangled when laid around the holding elements on the transfer chains.

Abstract: A method of producing a reinforced sheet by feeding a layer of foam material to a stitching machine at a rate greater than that at which the stitched material is produced by the machine. The stitching in the product is thus disposed below the surface of the foam and hence is not destroyed during subsequent flame-bonding.

Abstract: A dimensionally stable, padded, fabric of the type having a layer of carded, fibers reinforced by a woven fabric layer, warp knitted together by separate yarns is characterized by the carded fiber layer being unbonded, uncompacted and of intermingled, non-parallel fibers. Also by the woven fabric base layer being a fine mesh, thin, strong, tightly woven scrim of spun polyester fibers in the range of 28s to 40s. Also by the warp knit yarns being spun polyester fibers in the range of 16s to 24s. The knit yarns are embedded in the soft exposed batting face but are on the surface of the exposed scrim face to give that face high abrasion resistance.

Abstract: A fleece fabric is produced by feeding a fiber web to a reciprocating compound needle row and extending the web fibers across the needle row. A reciprocatory, rotary brush or comb, or a pin bar is used to feed the fibers to the needle row. The conventional cross folder can be dispensed with, and the fabric is stronger than when the web fibers are orientated before they are fed to the needles. The fabric has a density between twice and 15 times that of the constituent web.
