Crotchet Type Patents (Class 66/85R)
  • Patent number: 6131420
    Abstract: It is described a process for manufacturing in crochet galloon machines, ribbons of synthetic fabric provided with flexible hooks for quick-closing devices of the tear type, which process comprises a previous step of knitting a ribbon in which successive sequences of loops are formed. The ribbon is then submitted to a heat treatment adapted to substantially stiffen said loops previously shaped in an angle-bent conformation. Then a cutting operation is carried out on the stiffened loops so as to obtain one hook from each of them.A crochet galloon machine is also provided for forming said ribbons of synthetic fabric, said machine comprising a plurality of shaping elements adapted to form successive sequences of loops with the weft threads, a heat-treatment unit for setting the geometric shape of the loops, and a cutting device intended for cutting off the stiffened loops so as to obtain one hook from each of them.

  • Patent number: 6125666
    Abstract: There is provided a narrow width crochet knitting machine having a driving mechanism of a weft guide bar and two or more kinds of warp guide bars, which can form two or more kind of knitted loops in a narrow knitting space with a simple and compact mechanism. In a narrow width crochet knitting machine having a driving mechanism for independently and synchronously driving one or more weft guide bar, warp guide bars and a plurality of knitting needles, the warp guide bars comprise a plurality of guide bars for forming two or more kinds of knitted loops, at least one guide bar of the warp guide bars is arranged in a space for locating the weft guide bar, a support block of the one warp guide bar is arranged in a substantially identical plane with a support block of the weft guide bar, and the weft guide bar support block and the weft guide bar support block are vertically moved in the substantially identical plane by a main drive shaft independetnly from each other.

  • Patent number: 5924311
    Abstract: A multiplicity of knitting needles and one or more knitting needles are slid vertically along first and second needle beds, respectively, which are disposed in a back-to-back relationship with and spaced a predetermined distance from each other. The second needle bed extends along only one end portion of the first needle bed. And at the same time, a predetermined number of knitting yarn guides are swung and shogged. During that time, a monofilament bending means disposed near one end of the first needle bed reciprocates along the upper space between the first and second needle beds at an underlapping position to continuously form individual fastener elements by bending the monofilament and to knit the formed fastener elements successively in a warp-knit fastener tape by the back-to-back needles in the first and second needle beds simultaneously with the knitting of the tape.

  • Patent number: 5913903
    Abstract: A necessary number of knitting needles are slid at a predetermined timing along a multiplicity of parallel sliding grooves of a single needle bed, and a predetermined number of knitting yarn guides take lapping movements to form desired stitches of the knitting yarns while a monofilament bending means between one end of the needle bed and the yarn guides is operated at a predetermined timing for reciprocating along a predetermined number of knitting yarns at an underlapping position. During this reciprocating movement, a head-portion-holding member is moved between a holding position for holding a head portion of each fastener element from an inside thereof and a non-holding position, in synchronism with the bending of a monofilament.

  • Patent number: 5758519
    Abstract: A knitting machine and method for forming a composite band including an elongate knitted band and a drawcord secured to a front face of the knitted band by a covering yarn overlying the drawcord and stitched to the elongate band. The knitting machine includes a frame. A first knitting station is provided supported by the frame for forming the elongate knitted band. A second knitting station is provided supported by the frame and downstream of the first knitting station for receiving the knitted band after it exits the first knitting station. The second knitting station is operative to stitch the covering yarn to the knitted band from opposite sides of and across the drawcord to form a channel area defined between the covering yarn and the front face of the knitted band, the drawcord disposed in the channel area.

  • Patent number: 5680777
    Abstract: Installed on a crochet galloon machine is a device (1) for inserting alternately-interposed wefts, comprising two weft-inserting sliders (10, 16) carrying respective threading tubes (11, 17) each adapted to lay down a weft yarn (12, 18) to be interlooped in the article of manufacture (M) being worked. Each slider (10, 16) is movable along a respective weft-inserting guide (9, 15). The cyclic movements of the sliders (10, 16) are mutually offset according to a cycle fraction equal to the number of the provided weft-inserting bars (9, 15), so as to alternate laying down of each weft yarn (10, 18) with each chain stitch (6b)-formation cycle.

  • Patent number: 5653127
    Abstract: A device on a warp knitting machine for crocheting an elastic band with a coating and an elastic band made with this device. The band may also have picots at its edges, that is small loops. The device is intended to facilitate the production of very fine bands with a distribution of more than eight and especially twelve needles per centimeter of machine width and even more if possible. The coating should be patternable. The coating may be produced on only one or on both sides of the strip. The device has crochet hooks (4), a cuttler (80) to feed skeins of rubber-elastic threads (14) and a cuttler (20) to feed skeins of warp threads (22).

  • Patent number: 5452591
    Abstract: An elastic band is fabricated with an integrated drawcord utilizing a crochet-type warp knitting machine by initially knitting a finished elastic band and, then, re-routing the finished band back through the knitting machine to a second knitting location at which fabric piercing needles are utilized to knit additional warp and filling yarns while a drawcord is simultaneously fed between the piercing needles to form a covering web over the drawcord defining a tunnel area between the covering web and the finished band in which the drawcord is captured.

  • Patent number: 4297156
    Abstract: A wall covering has a textile element secured to a backing by a thermo-fusible material. The textile element is formed of compacted zig-zags of the warp formed by a crocheting machine and held on the backing by chain stitching parallel to the direction of movement in the machine. The chain stitching along the selvage edges of the element precut the backing for removal of excess backing by tearing. The covering is coupled by a final step of fusing the thermo-fusible material.

  • Patent number: 4034579
    Abstract: An apparatus for producing fringed braid comprising a reciprocable weft guide for meshing weft yarn with warp to form a braid with projecting loops of the yarn. A sliver guide is reciprocable to form loops of fringe sliver. One guide is displaceable from one side to the opposite side of the other guide whereby the yarn and sliver loops are formed interlooped. Sliver loop halves are interconnected by warp threads. A similar apparatus has an additional weft yarn guide, two braids being simultaneously produced, with projecting yarn loops of each being interlooped with loops of a single sliver.
