Definitions

  • the present invention relates to an improved rack, or creel, for supplying bundles of ribbon-like fibres to textile machines such as drawing frames, lapping machines and any similar machine.
  • the bundles of ribbon-like fibres, from the various boxes placed side by side, one to the other, are made to pass through the supply pulleys of the idler rollers and drive rollers, which are driven by the machine head.
  • the said organs are mounted on a frame for lifting and transferring the bundle of fibres, which changes the direction of conveyance several times passing from a horizontal to an oblique direction, or to a vertical direction and vice versa, until entering the drawing rolls of the drawing frame.
  • the bundles of fibres are supported, during their journey, by stationary boards; i.e. by fixed surfaces.
  • the present invention proposes an improved rack used in textile machines for supplying bundles of ribbon-like fibres, extracted from collection boxes, in which the said rack has at least one lifting and transfer track comprising endless flexible belts moved, one above the other, in the same direction and with the same value of motion and the said flexible belts are far enough apart to receive, with suitable compression, the bundle of ribbon-like fibres in order to convey it without any alteration to the rotating comb head or in any event to the entry of the work unit.
  • the present invention also proposes that the endless flexible belt track, for lifting and moving the bundle of ribbon-like fibres, has its bottom conveyor branch deformed in an essentially concave shape, due to the effect of the compression action of the bundle of fibres, which forces the section of flexible belt below onto a rigid fixed support below of an essentially concave shape in order sufficiently to envelop the bundle of fibres, guiding the latter in a perfect sideways position towards the entry to the rotating comb head.
  • the endless flexible belts of the improved rack covered by the present invention have a roughness suited to the type of fibre being supplied and, moreover, the circumferential surface of the drive rollers, which operate the flexible belts, have sufficient roughness to prevent even the slightest slipping of the flexible belts as they are driven round.
  • 1 is the bundle of fibres positioned and sufficiently compressed between the branches of the flexible belts, to convey it and transfer it to rotating comb head 7 with the precise aim of not subjecting it to even the slightest lengthening, or to stress which causes distortions which affect the quality of the finished product;
  • 2 is the collection box of the bundle of fibres below distributor plate 4;
  • 3 is the bundle of fibres extracted from box 5 below and the said bundle of fibres 3, joined with the other bundles of fibres extracted from the other boxes, supplies the drawing frame;
  • 6 is the top inclined flexible belt for vertically lifting the bundle of fibres 1, which must be conveyed from above to rotating comb head 7;
  • 8 is the drive roller which entrains the flexible belt and the said roller 8 is operated by motor 20;
  • 9 is the horizontal position top flexible belt;
  • 10 is the creel, or top part of the rack for pulling up the ribbons by means of a series of unwinding pulleys and drive cylinders
  • transmission rollers 15 The passage from one position to another occurs by means of transmission rollers 15; 14 is a pre-drawing module which helps to make the bundles of fibres 3 joined together uniform and homogeneous; 16 is the self-regulator device usually present in first-passage drawing frames; 21 is the rigid fixed support below the flexible branch of the endless belt, and the said fixed support 21 has an essentially concave shape.
  • the bundles of fibres 3 extracted from container boxes 5 are joined together to produce a uniform, homogeneous bundle of fibres with the fibres properly extended and essentially parallel.
  • the bundles of fibres 3 pass through pre-drawing module 14, or through self-regulator device 16, to be conveyed as a single bundle of fibres 1 to the entry of the drawing unit and rotating comb head 7.
  • Entrainment of the bundle of fibres 1 should present no so-called "false drawing” to which bundles of fibres may be subjected.
  • "false drawing” is that lengthening which materials that are easily deformed undergo, during their transfer onto textile machines, due to the effect of excessive tension or friction.
  • the important arrangement of the present invention enables the bundle of fibres 1, once introduced between the facing branches of flexible belts 6, 12 and 9, to be accompanied, with sufficient pressure and perfectly guided sideways, to the vertical work unit without being subjected to lengthening distortion between the point of entry and the point of exit from the said flexible branches.
