Definitions

  • the present invention relates to a method and a device for spreading a tubular knitted fabricated product, such as for example a stocking, threaded onto a support form.
  • each stocking has a large number of folds which must be eliminated by hand by an operator, through an operation which, in the jargon, is called "pinching” : the bottom fabric is pinched between the tip of the thumb and the operator's index finger, in correspondence with the bottom part to be stretched, then the bottom thus retained is subjected to a transverse traction relative to the form of support and , finally, released. In this way, the bottom is stretched on the corresponding shape and consequently the folds disappear: this operation must be repeated when the bottom has a lot of folds. But, since this operation is performed manually, the presence of at least one operator expert is required for each work team, which increases the manufacturing cost of the finished product. Added to this is the fact that, in the event of a drop in attention on the part of the operator, the quality of the finished product is seriously compromised.
  • the advantages obtained thanks to the present invention essentially consist in the fact that it is possible to effect the elastic extension of the knitted fabric of a tubular manufactured product and consequently the elimination of the folds which normally form during its threading on forms automatically, quickly and with extreme precision; in that it is possible to predetermine and effect the elastic elongation of the fabric of the manufactured product in relation to the material with which it is made; in that it is possible to increase the speed of production and therefore significantly reduce the cost of manufacturing tubular knitted products; in that it is possible to easily associate a device according to the invention with machines for processing already existing tubular knitted products; in that a device thus produced is simple, economical and reliable to manufacture even after a long period of operation.
  • FIG. 1A schematically shows a side view of a device according to the invention, in the rest position;
  • Fig. 1B shows the device of FIG. 1A in the advancement phase with opening of the clamp to grab a stocking;
  • Fig. 1C shows the device of FIG. 1A in the gripping phase of a lateral portion of the bottom;
  • Fig. 1D represents the device of FIG. 1A in the retraction stroke with bottom stretch;
  • Fig. 1E shows the device of FIG.
  • FIG. 2A shows a plan view of the device of FIG. 1A
  • Fig. 2B shows a plan view of the device of FIG. 1B
  • Fig. 2C shows a plan view of the device of FIG. 1 C
  • Fig. 2D represents a plan view of the device of FIG. 1D
  • Fig. 2E shows a plan view of the device of FIG. 1E.
  • a stop element (6) is interposed between the head of the clamp (1) and the corresponding control cylinder (2), so as to limit the operational return stroke of the clamp (1 ) and exert a push on the back of each jaw to generate a moment of opening of the clamp (1) and release of the bottom (4).
  • an elastic blade (10) is mounted astride, longitudinally, on the two jaws of said clamp (1) so as to allow closing in the rest position.
  • each axis (11) is in contact with the internal surface of the corresponding profile of the cam (3) and it is subjected to a thrust which produces a moment of closing of the clamp (1), in cooperation with the blade (10).
  • the axes (11) are located outside and beyond the cam (3).
  • each jaw of the clamp (1) receives a push from the element (6) so as to cause the opening of the clamp (1) and the loosening of the bottom (4).
  • the bottom pull (4) thus produced has the effect of stretching the mesh of the fabric and eliminating the folds that existed.
