  • Publication number: 20140060119
    Abstract: A method, an elongating device, a Raschel knitting machine comprising the elongating device for producing nets with elongated stitches and a net comprising elongated stitches is described. The method comprises the steps of continuously generating new loops for elongating the two rows of loops by additional loops and dragging the rows of loops in a machine direction, generating a first stitch of the weft by joining the weft to a loop of the first row and to a loop of the second row, and positioning the first stitch across a surface of an elongating device for preventing the first stitch from traveling with the warps knitted to loops in the machine direction. The joining is configured for elongating the first stitch by pulling additional weft material, and the surface of the elongating device is carrying out a reciprocating movement towards the first stitch. Further, an elongating device for elongating of the stitches is described.

  • Patent number: 7739888
    Abstract: The invention relates to a method and related equipment for manufacturing shaped fabrics or anatomically shaped tubular hosiery and knitwear items, obtained with Raschel looms having preferably two parallel needle beds and automatic latch needles. During the knitting process, by gradually varying the height of the needle bed and of the sinking plane lying above with respect to the needles sliding in the same bed, knitting density can also be suitably changed. As a consequence, concerned anatomic parts such as the bodice and ankles of a pair of tights or a stockings as well as the waist and sleeves of a sweater can be shaped with higher accuracy and effectiveness.

  • Publication number: 20080276653
    Abstract: To simplify the setup of a bar and associated tools of a knitting machine and to improve the degree of precision regarding fineness and the level of sturdiness of the tools and bar system, the holding parts (7, 9) of the tools (4, 5) of the tool set (2) are configured differently. On the holding parts (7) of at least one tool type, means (22) are provided for positioning the tools (4) on the bar and thus means for defining the division. Separate positioning means for positioning and defining the division may be assigned to the other tools (5). Alternatively, they may be positioned by the tools (4) of the first type, between which they are accommodated. If positioning grooves are provided in the bar or parts thereof, these grooves may be set up for twice the distance of division, which results in robust and mechanically stable solutions with finer divisions.

  • Patent number: 5442936
    Abstract: A device for clamping and guiding crocheting needles for a crocheting machine. On the one hand a clamping device for the crocheting needles and on the other hand a knock-over comb are to be created, which permit a very fine spacing. To this end, in the bottom part (27) and in the clamping cover (29) of a clamping device (12), opposite, straight needle beds (73, 74) are arranged closely together. The needle beds (73, 74) have wall surfaces that are inclined in a V-shape. A knock-over comb (20, 80) fixed to the machine has upwardly projecting teeth (86) for the crocheting needles. The spacing of the needle beds and guide elements is at least 12, in particular 14 per centimeter of machine width. The holding bar (23) fixed to the machine and the bottom part (27) of the clamping device (12) have recesses, in particular chambers (77, 76) that face one another, which permit the clamping device to move too close to the teeth (86).

  • Patent number: 5295372
    Abstract: In a warp knitting machine at least one swingable guide bar is driven in a shogging direction. This displacement is achieved through a drive member via a hinged push rod in dependence upon a path time function. This path time function is formed by overlapping a ground function with a compensation function. The ground function is the targeted displacement movement of the guide bar for proper lapping. The compensation function compensates for an axial mislap and possible collision during the swing-through of the guide bar. The compensation occurs at least during that segment corresponding to the passage of the guides through the needle gaps. Preferably however, compensation occurs over the entire ground function. This compensation substantially reduces the danger of collision between the guides and the needles.

  • Patent number: 4723424
    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 clamping device for attaching crochet needles to the needle bar of a galloon crochet machine or Raschel loom. The clamping device consists of two body pieces, a lower piece and a clamping lid, which are fastened together by means of clamps. In one embodiment the body piece holds the needle shafts, a spacer inserted into each interval between needles, and a support piece between the shafts of a needle and a receptacle in the lower piece. This results in the formation of needle beds. In the other embodiment very shallow grooves are milled opposite one another in both body pieces. These are only a fraction of half the height of the needle shafts, leaving the major part of the needle shaft's height free after clamping.

  • Patent number: 4449382
    Abstract: A warp knitting machine typically equipped with latch-type needles, trace comb, and numerous guide bars for underlapping purposes. The keep-off rails for the pattern threads, running from the hook needles or guides to the latch-type needles, are mounted behind several or all latch-type needles, outside the operating range of the needle latch, their motion being synchronized with the motion of the needles. Typically, the lamellar keep-off rails, placed behind the latch-type needles in the direction of the oscillating movement, have an opening which is directed towards the needles. The opening in the rails has the shape of an orbit section which is slightly greater than the orbit section described by the latch of the needle. In a preferred embodiment, the lamellar keep-off rails are crimped in the direction of the shifting or shogging motion in the operating range of the needle latch.
