Definitions

  • the present invention relates to a method and a Device for aligning substantially tubular Textile goods, in particular stockings, fine stockings, Socks or the like that have an asymmetry.
  • Under asymmetry is both an asymmetry of shape and for example the heel leveling of a stocking or the top seam of a sock, as well as a color or weave asymmetry such as a woven-in characteristic thread understand.
  • Under textile goods are not only woven, knitted or knitted, made from fibrous materials Goods, but also those made of other materials in other manufactured to understand the comparable Properties, in particular with regard to elasticity and Possess surface quality.
  • socks and stockings are made on circular knitting machines made with a so-called pendulum heel.
  • the socks essentially leave the knitting machine in the form of a hose, one at one end special shape, the so-called gore-line. This end is closed with a seam and then forms the top of the sock.
  • gore-line This end is closed with a seam and then forms the top of the sock.
  • the socks After sewing lace, sometimes even after knitting, the socks are bleached or dyed. You leave the Bleaching or dyeing plants comparable in an unsightly form the shape of socks after washing and must then by molding into a salable condition to be brought.
  • the textile goods are subject to knitting or weaving errors Check to sort out defective goods. For this it is known to put the socks or stockings on a flat plate and then look at it from both sides.
  • this object is achieved by a method of the type mentioned, in which the textile goods on a essentially cylindrical shape, the shape with the textile goods mounted on it rotated about a longitudinal axis the position of the asymmetry and the respective position of the shape can be detected and the shape according to the detected position of the asymmetry in a predetermined Position is rotated.
  • the textile goods can be completely misaligned in any Lay out, for example, from a basket or directly from one Dyeing or bleaching machine coming onto the mold become and are automatically in a predetermined without manual labor Position aligned in which it is connected to a processing machine can be passed on.
  • the winding up the textile goods to a substantially cylindrical shape facilitates the detection of the asymmetry of the textile goods essential.
  • the textile product is preferably drawn onto the mold in such a way that the textile goods with the exception of asymmetry smooth abuts the mold and the portion protruding from the mold the textile goods is recorded.
