  • the apparatus comprises conveying means for conveying fibrous material from feed means to the spinning means along a conveying path in which the fibres are subjected to an opening action, the conveying means including a rotating roller having an apertured peripheral wall on the outer surface of which the opened fibres or the fibres being opened are conveyed and suction means for applying suction internally of the roller to remove impurities from the fibres and withdraw the impurities through apertures in the peripheral wall.
  • the present invention relates to the open-end spinning of textile yarns and more particularly to an improved apparatus for extracting impurities from the fibrous material prior to the material being fed to a spinning zone.
  • apparatus for the open-end spinning of textile yarns in which fibres are formed into a yarn by open-end spinning means into which the fibres are fed in discrete manner comprising conveying means for conveying fibrous material from feed means to said spinning means along a conveying path in which the fibres are subjected to an opening action, the conveying means including a rotating roller having an apertured peripheral wall on the outer surface of which the opened fibres or the fibres being opened are conveyed and suction means for applying suction internally of the roller to remove impurities from the fibres and withdraw the impurities through an aperture in the peripheral wall.
  • FIG. 1 is a diagrammatic part sectional side elevation of an open-end spinning machine for which the present invention is particularly suitable.
  • FIG. 2 is a sectional side elevation of the fibre opening elements of the machine shown in FIG. 1.
  • FIG. 3 is a cross-sectional view of the elements shown in FIG. 2 taken on the line III-III in FIG. 2.
  • FIG. 4 is a cross-sectional scrap view taken on the line IV-IV in FIG. 2 and indicating the position of a filter.
  • a sliver is fed to a rotating toothed feed roller 2 through an opening 14.
  • the fibres are conveyed on its peripheral surface until stripped therefrom by a rotating opening roller 3 with an opening action.
  • the opening roller 3 is mounted in a cavity 4 of a housing 5 and is provided with teeth 27 on its periphery.
  • the rotation of opening roller 3 is such that its peripheral speed is greater than that of the feed roller 2 in order to comb and open outthe fibres.
  • Fibres are conveyed on the periphery of the opening roller until they reach the entrance to a fibre feed duct 6 extending tangentially to the opening roller 3, where they leave the opening roller and are conveyed down the fibre feed duct 6.
  • the fibres emerging from the fibre feed duct 6 are deposited on an internal fibre collecting surface 7 of a rotating spinning rotor 8.
  • the fibres are taken off the fibre collecting surface 7 of the rotor 8 by twisting them into the tail end of a spun yarn 9, which is withdrawn through a doffing tube 10 by a pair of delivery rollers 11 to be wound into a package 12 in a conventional manner.
  • the feed roller 2 is enclosed in a casing 13 in which is provided the opening 14 for the sliver.
  • the feed roller 2 is provided with a toothed surface which is formed by a saw toothed type wire 15 wound around the roller to provide a number of rows spaced apart across its face.
  • the opening roller 3, mounted within the cavity 4 is also provided with a toothed surface which is formed by a saw tooth type wire 27 wound around the roller to form a number of rows across the face of the roller and the arrangement is such that fibres carried by the feed roller 2 are stripped therefrom by the rotating opening roller 3 at an inlet 16 to the cavity 4.
  • the cavity 4 is provided with a cover 23 (as best seen in FIG. 3).
  • the opening roller 3 is generally of a dish-shaped configuration and is provided with a bored hub 18 by which it is mounted on a driving shaft 17.
  • a web 19 extends radially from one end of the hub and terminates in a peripheral wall 20 in which a plurality of apertures 21 are formed.
  • the apertures 21 comprise first apertures 21 spaced around the peripheral wall 20 and extending radially therethrough and second apertures 21 also spaced around the circumference of the peripheral wall 20 and extending at an oblique angle to a plane at right angles to the axis of the opening roller.
  • Communicating with the interior of the opening roller 3 is a suction duct 22 (as seen in FIG. 2) connected to a source of suction (not shown) which in operation serves to extract impurities from the fibres carried on the periphery of the roller and withdraw them through the aperture 21 for conveyance through the suction duct 22 to a waste collection point.
  • a suction effect resulting from either the rotating spinning rotor or from an independent source is also produced in the fibre feed duct 6.in order to aid the removal of fibres from the opening roller 3 and to convey them in discrete form down the duct 6 to be deposited on the fibre collecting surface 7 of the spinning rotor 8.
  • a baffle insert 24 is provided which is fixedly attached to the housing and which effectively separates the two air flows.
  • the suction duct 22 opens out into a slot 25 in the insert 24 and the slot 25 is so shaped and directed as to cause suction to be applied to the wall 20 of the roller 3 at a point subsequent to the'point of transfer of fibres from the feed roller 2 to the opening roller 3.
  • the point at which suction is applied to the wall 20 is close to the point of transfer of fibres from the feed roller 2 to the opening roller 3, but is spaced from the point of fibre transfer by a sufficient distance to allow the fibres to be properly laid on the periphery of the opening roller before being subjected to the effect of the suction.
  • the baffle insert 24 is so shaped as to reduce to a minimum any dead space in the flow path of the air sucked through the apertures 21 and into the duct 22 via the slot 25.
  • a further trash re moval point in the form of a trash removal duct 26 which extends from the periphery of the opening roller 3 to the outside of the'housing.
  • the impurities being heavier than the fibrous material, tend to lie on the outside of the material carried round on the roller 3 and are stripped therefrom by a stripping edge 29 of a valve member 30 or'are flung into the trash duct 26 due to the high rotational speed of the opening roller 3.
  • a trash collection box (not shown) may be provided at the side of the housing 4 which is periodically emptied.
  • the trash removal duct 26 may be completely closed by the valve member 30 in order to prevent the loss of good fibres. In such cases, it is necessary to allow air to enter the cavity 4 so that the necessary air flow conditions required for satisfactory removal of fibres from the opening roller 3 can be achieved.
  • an air inlet 31 is formed in the side wall of the housing 5 which is positioned on the opposite side of the insert 24 to that of the slot 25.
  • the aperture of the air inlet 31 may be varied by adjustment of a shutter 32. Under certain processing conditions air inlet 31 may be closed while the trash removal duct 26 is fully open. In other cases, in order to obtain optimum air flow conditions both the air inlet 31 and the trashremoval duct 26 may be opened by predetermined amounts dependant on the requirements of the processing conditions.
  • the present invention is applicable to the open-end spinning of short, medium or long staple fibres, but is particularly suitable for use in processing long staple fibres which, when opened by an opening roller ar rangement as hereinbefore specifically described, liberate a large amount of dust (such as spin finish with acrylic fibres) and debris (such as fibre particles and scale in natural fibresas wool).
  • the feed and opening rollers are clothed with a saw tooth type wire. It will however be appreciated that if desired the surfaces of these rollers may be provided with a clothing formed by pins.
  • Apparatus for the open-end spinning of textile yarns comprising:
  • open-end spinning means into which fibres are fed in a discrete manner and in which the fibres are formed in a yarn
  • conveying means for conveying fibrous material from the feed means to the spinning means in a conveying path in which the fibres are subjected to an opening action
  • a rotatable opening roller included in said conveying means and having an apertured peripheral wall from the fibres on the opening roller through apertures in the peripheral wall
  • the fibre removal passage withdrawing fibres from the outer surface of the opening roller and feeding them in discrete manner to the spinning means and i I g. a stationary insert which is surrounded by the peripheral wall of the opening roller and wherein said .insert acts as a baffle to impede the flow of air between the fibre removal passage and the suction means.
  • suction zone is spaced from the opening zone in the direction of rotation of the opening roller and the spacing of the suction zone from the opening zone allows the fibres to be openlyarranged on the outer surface of the peripheral wall of the opening roller before reaching the suction zone.
  • trash removal means providing a trash removal zone spaced from the suction zone in the direction of rotation of the opening roller, the trash removal means being arranged to remove trash from the fibres outwardly from the outer surface of the peripheral wall of the opening roller.
  • the said feed means comprises a feed roller to which a supply of fibrous material is fed and from which fibrous material is transferred to the opening roller with an opening action in the opening zone.
  • Apparatus according to claim 1 wherein a casing surrounds the opening roller, and wherein an air inlet is provided for supplying air into said casing between the suction zone and the fibre removal zone.
