Definitions

  • ABSTRACT The specification describes a device for spinning fibre [30] Fore'gn Apphcatlon Pnonty Data sliver comprising means defining a spinning chamber July 28. 1970 Germany P 2 37 29 receiving fibres from an opening up means for opening up a fibre sliver being fed to it by a feed means.
  • the [52] [1.5. CI. 57/5835, 19/105 feed means have as one element a draw-in roller ar- [51] D0 g 15/40 ranged on a holder and as a further element a feed [58] Field of Search 57/58.8958.95; plate.
  • One of these elements of the feed means is resil- 1 /1 iently fixed at one end for producing a relative spring force between the feed plate and the draw-in roller for 156] Referen s Cit d exerting a gripping pressure.
  • the present invention relates to fibre sliver spinning apparatus and more especially to such apparatus comprising a feeding and opening device for supplying the fibre sliver to be spun to a spinning chamber.
  • the opening device For opening up the fibre sliver to be spun the opening device provided upstream from the fibre sliver spinning part of the apparatus can comprise rapidly running opening rollers which are provided with needles or teeth.
  • the opening roller For supplying the fibre sliver to the opening roller use is made either of a pair of gripping rollers or a feeding groove with a draw-in or feed roller, between which the fibre sliver is held back.
  • Feeding grooves have the advantage over pairs of gripping or nip rollers that the gripping zone can be arranged closer to the tip circle of the teeth or needles of the opening roller so that a better retention of the fibres is ensured.
  • the feeding groove is in a part which is journalled on a pin and this part is pressed by means of spring force against the draw-in roller. See U.S. Pat. No. 3,360,918 for example.
  • faults can occur in the yarn if the pivoting of the part with the feed groove and consequently the gripping action exerted by it is impaired by insufficient lubrication of the bearing of the grooved part on its pin owing to its virtual movement or owing to dirt (see Cizek: Processing of Man-made Fibres by the Break-Spinning Method. Summary of Lecture, International Conference about Open End Spinning, Moscow 1969, page 7/LC). Faults in the yarn, however, also occur in these cases in which part of the sliver is not gripped or nipped or is only gripped to an insufficient extent owing to a one-sided engagement of the feed groove on the draw-in roller.
  • One aim of the present invention is to provide a feed device which is of simple construction and needs little servicing but nevertheless provides a gripping action which is always constant or even over the width of the sliver and can be rapidly and accurately adjusted.
  • FIGS. 1 to 3 show three embodiments of a feed de- .vice in accordance with the invention with a feed plate DESCRIPTION OF PREFERRED EMBODIMENTS
  • the fibre sliver to be spun is supplied to an opening roller 1 provided with needles or teeth by means of a feed device which comprises an upper flat feed plate 2 and a draw-in roller 3 as can be seen in FIG. 1.
  • the feed plate 2 exerting the gripping or nipping pressure on the fibre sliver is in the form of a cantilever leaf spring having its fixed end mounted by means of screws 40 on a bracket 4.
  • the free end of the feed plate 2 can have a recess a (see FIG.
  • FIG. 2 shows a feed plate 21 in the form of a cantilever leaf spring whose free end matches the curvature of the draw-in roller and is preferably also provided with a recess a as shown in FIG. 6.
  • the other end of the feed plate 21 is held in a bracket 5 by a setscrew 50.
  • the bracket includes a sliver funnel 51.
  • the bearing bracket 5 is journalled on a pin 52 attached to the frame of the apparatus and is held against rotation by means of a nut 520.
  • the weight 61 is slid into the desired position on the lever 6 and then fixed in this position by means of the screw 610. Following this the lever 6 is inserted into the hole in the bracket 5 provided for it and the nut 520 is loosened to such an extent that the bracket can swing in response to the weight 61 about the pin 52 and accordingly the feed plate is pressed with the required force against the sliver, that is to say towards the draw-in roller 3.
  • the setting operation is ended.
  • the feed plate 22 can consist of non-resilient material which is fixed to the free end of a cantilever leaf spring 220 as shown in FIG. 3.
  • the leaf spring 220 has one end detachably mounted in a bracket 62 connected with the frame of the apparatus by means of a screw 63 so that the same gripping effect and the same adjustability of the gripping pressure is produced as is the case with the above described embodiment.
  • Apparatus for processing fibre sliver including an opening roller provided with needlelike projections for opening up a fibre sliver fed to it by feed means, said feed means having as one element a draw-in roller mounted adjacent to said opening roller by a holder and as a further element a feed plate cooperating with said draw-in roller, the improvement comprising a cantilever spring carrying one element of the feed means for producing a spring force between said feed plate and said draw-in roller for exerting a gripping pressure.
