  • Publication number: 20140245578
    Abstract: “Tinkles” (also known as “gotchas”) (see reference number 20 in FIGS. 1 and 2) are portions of knitted metal loops produced when a tube of knitted wire mesh is cut into individual pieces. In the prior art, tinkles have been considered a fact of life and the approach has been to try to shake them out of the mesh or immobilize them on or in the mesh. By producing a knitted tube (11) having alternating segments (12,13) of knitted rows of yarn and knitted rows of wire, completely tinkle-free knitted socks are produced which are used to produce completely tinkle-free knitted wire mesh filters. Knitted wire mesh filters that cannot release tinkles because they do not have any tinkles can be used in such applications as fuel filters and airbag filters.

  • Patent number: 8484998
    Abstract: A circular knitting machine with a fine gauge includes a circular cylinder and a sinker holder annularly located on an outer side of the circular cylinder. The circular cylinder has a plurality of knitting needles parallel with the axial direction of the circular cylinder to move alternately, and an annular top surface corresponding to the knitting needles. The sinker holder has a plurality of retaining slots to hold a plurality of sinkers. Each sinker has a slide edge, a movement edge extended from the slide edge at the same elevation to the annular top surface and located above the annular top surface, and a loop forming nose located between two neighboring knitting needles. Each retaining slot has a leaning surface in contact with the slide edge to allow the sinker to move towards the annular top surface to proceed a loop forming movement.

  • Publication number: 20120148772
    Abstract: A coated textile sleeve for routing and protecting elongate members, combination thereof, and method of construction is provided. The textile sleeve has an elongate knit wall constructed from weft knit yarns. The knit wall has an inner surface providing a generally tubular cavity in which the elongate members are received and protected. The inner surface is formed, at least in part, by laid-in yarn to provide a soft, non-abrasive surface for dampening contact with the elongate members being protected to facilitate absorbing vibration, which in turn, reduces the frictional wear of the elongate members being protected. Further, the knit wall has an outer surface with a flexible, impervious elastomeric coating thereon. The elastomeric coating allows the knit wall to substantially retain its flexibility as knit, provides enhanced protection against the ingress of fluid and other contaminants, and providing added dampening to absorb vibration.

    Abstract: A break-away mount for mounting a fabric scanner to the central support shaft in a circular knitting machine. The mount normally fixes the scanner in a stationary position on the end of a mounting arm of the mount, but if sufficient force is exerted on the scanner in the direction of movement of the fabric, the mount breaks away and allows the scanner to rotate about the support shaft so that the scanner can move along with the fabric. If the amount of such rotational movement exceeds a predefined value, then the break-away mount also releases the mounting arm so that the mounting arm can pivot about a non-vertical axis to allow the scanner to descend with the descending fabric tube. By detecting the breaking away of the mount, the knitting machine can be stopped in time to prevent damage to the scanner and mount.

    Abstract: A method for manufacturing socks with a circular knitting machine having at least two feeds or drops, consisting in producing the sock starting from its opposite end with respect to the toe. The toe is produced by using at least two feeds simultaneously and by actuating the needle cylinder with an alternating rotary motion so that two sets of needles, arranged on mutually opposite sides, are made to knit respectively at one of the at least two feeds and at the other one of the at least two feeds, forming stitches simultaneously, and gradually decreasing, for a preset number of rows of stitches, the needles of the two sets that are made to knit.

  • Patent number: 7036340
    Abstract: A heat dissipating system of a high-speed circular knitting machine includes a super low temperature air gun. Cold air is ejected from a cold air outlet of the super low temperature air gun for carrying away the high heat produced by a cylinder base during a knitting process. The super low temperature air gun is connected to an extension pipe and extended to a gap between a cutting disc and a pressing plate, or saddle bases, or a lower rhombus ring and two saddle bases, or yarn feeding nozzles. Cold air ejected from the cold air outlet passes through the gap to the cylinder base or other peripheral components of the high-speed circular knitting machine to achieve the heat dissipating effect. The super low temperature air gun is installed inside a leg for supporting a yarn supplying device or on its external surface or on a yarn feeding ring.

  • Patent number: 6923026
    Abstract: A method for hand-crafting a rug includes obtaining a first sock loop and twisting the first sock loop to form one loop four strands thick. A second sock loop is pushed halfway through the one loop and a new sock loop is pushed through the two end loops of the second sock loop. Additional sock loops are drawn through selected socks and through each other. This step is repeated until a chain is formed. Another sock loop is wrapped around the chain and pushed through one of the additional sock loops. A new one of the successive sock loops is pushed through the first sock loop and a newer one of the successive sock loops is pushed through a space closest to the old loop. The old loop is pushed over the new successive loop until reaching an opposite end of the chain.

  • Patent number: 6920767
    Abstract: The invention relates to tubular knitwear items (1) suitably shaped or modeled without the usual cutting and sewing operations and preferably without using elastic yarns. According to the jacquard design and/or to the work cycle of the textile machine, the invention enables the production of differentiated-growth fabric in specific areas or zones by the programmed exclusion of loops or knitted courses and the simultaneous production of exceeding stitches or inner frills (Bi), thus obtaining a programmed three-dimensional deformation of the knitted tube according to manufacturing needs.

  • Patent number: 6901776
    Abstract: A method for circularly knitting an elastomeric yarn into a knitted fabric is provided. The method includes: operating a circular knitting machine at a machine rate, retaining a free end of the elastomeric yarn in a substantially relaxed condition, and taking up the free end into the circular knitting machine while feeding the elastomeric yarn at a first feed rate. The first feed rate maintains the elastomeric yarn in the substantially relaxed condition. The circular knitting machine continues to operate at the machine rate during the taking up of the free end.

  • Patent number: 6845284
    Abstract: A method and system for designing circularly knitted garments are provided. The method includes designing a model of the circularly knitted garment, stretching the model from a first size to a second size, and governing the stretching with one or more user definable rules. The system includes a circular knitting machine, a controller for controlling the circular knitting machine with a machine code, a tool for saving a model of the circularly knitted garment as a first output, and a conversion program for converting the first output into the machine code. The tool has a stretching function for changing a size of the first output using one or more user selected rules.

  • Publication number: 20040200242
    Abstract: A knitting machine and a method to be accomplished on said machine are described, which are suitable for the production of knitwear from hard, inelastic thread material, e.g. from metal threads. According to the invention, at knitting systems (8a, 8b) provided for this purpose, knitting needles (2) are raised to pick up threads, which are then preformed over the upper edges of knocking-over/holding-down sinkers (3) to form loops. Thereafter the stitch formation takes place by needle and sinker movements directed in opposite directions in the manner of the relative technique.
