Definitions

  • a conventional circular knitting loom comprises, on a frame, a needle holder, or needle bed, circular, arranged to be driven in rotation by a motor, an annular cam holder, the cams of which are arranged to drive the needles in vertical displacement , coils of knitting yarn and needle thread guide and a cage, arranged to be rotated with the needle holder, for storing the knitted fabric leaving the needle holder.
  • a storage cage includes, for example, a pair of pinch rollers, between which the tube is flattened, and a storage roller, on which the flattened mesh tube is pulled and wound.
  • the method of storing a knitted fabric emerging in the form of a tubular sheet of a needle holder of a circular knitting loom consists, at the exit of the needle holder, of pinching the sheet, to fold it into two sides pressed against each other, and to wind the tablecloth on a storage roller ensuring at the same time the drawing of the knitted tablecloth at the exit of the needle holder.
  • the present invention aims to overcome this drawback.
  • the present invention relates to a method of storing a knitted fabric emerging, in the form of a tubular sheet, from a rotary needle holder of a circular knitting loom, in which the knitted fabric is wound on a roll. storage driven in rotation with the needle holder, method characterized in that, at the outlet of the needle holder, the tubular sheet is opened along a portion of one of its generatrices to lay it flat and the rolls flattened on the storage roller.
  • US-A-3,855,822 teaches to cut a tube along a generator but not to lay it flat.
  • DE-A-1 903 527 teaches cutting well but followed by an operation of joining the cut edges.
  • the tubular sheet in order to open the tubular sheet, it is stretched and clamped substantially perpendicular to its axis, it is cut out in the nip zone then it is moved apart to extend its circumference along a pull roller.
  • the invention also relates to a circular knitting loom according to claim 3.
  • the loom comprises a frame 1 on which is mounted a needle bed 2 carrying a series of knitting needles 3, a support 4 of a series of cams 5 and a creel 6 support of supply coils 11 and unwinding eyelets 12.
  • a storage cage 7 is arranged under the needle bed 2.
  • a motor 8, fixed to the frame, is provided for, by means of a pinion 9 and a toothed crown 10 integral with the needle bed 2, to drive that -this in rotation about a vertical axis 15 and, with it, the storage cage 7, by means of arms 32.
  • the cage 7 is rotatably mounted on a pivot 16 secured to the base 17 of the frame to which is fixed a conical toothed crown 18.
  • the cams 5 of the fixed cam holder 4 drive the knitting needles 3 in vertical displacement for knitting the knitted stitches.
  • the knitting threads from the bobbins reach the needles via the unwinding eyelets 12, near the bobbins, and the thread guide 13, near the needles 3, here attached to the cam holder 4.
  • the circular knitting loom as just described briefly, is perfectly known to those skilled in the art.
  • the storage cage 7 comprises, in the direction of advance 19 of the knitting, a tightening and preforming frame 20, in a plane substantially orthogonal to the axis 15, a pair of pinching bars 21, relatively close to each other. on the other in a horizontal plane, a pair of stretching and spacing bars 22, in a slightly inclined plane and forming between them a dihedral opening here about 90 °, at the top of which is placed a roller drawing 23, just under one end of the pinch bars and mounted to rotate freely, a cutting tool 24, between the other ends of the pinch bars, a pulling roller 25, just under the spaced ends of the bars drawing 22, deflection roller 26, drawing roller 27, with ends helical inverted pitch, and a storage roller 28, the four rollers being parallel to each other (Figure 3).
  • the four rollers are pivotally mounted on the arms 32, the rollers 26 and 27 being free to rotate and the rollers 25, 28 being driven in rotation about their axis by a kinematics now described with reference to FIG. 4.
  • the rotation of the cage 7 on the pivot 16, above the toothed ring 18 rotates a bevel gear 29 at the end of a rotary shaft secured to the cage 7.
  • the pinion 29 rotates a first return gear 30 which, by via a speed variation coupler 31, drives a second return gear 33 which drives the pulling roller 25.
  • the cutting tool 24 is here a cutting wheel mounted on a drive motor.
  • a tubular sheet of meshes of 1 meter in diameter is stored without folds in the form of a 3.14 m wide flank of mesh wound on the roller 28.
