Definitions

  • the rotor body is made of a lightweight material having mechanical properties suitable for high-speed rotation, such as an aluminum alloy or a rigid plastic, for example, styrol resin.
  • the cup interior forming the fiber collection surface is lined with material which has good spinning properties for fiber supplied to the cup, such as brass, chromium, nickel, Teflon, hardened gold, or a liquid coating such as varnish or enamel. If the rotor body material and the lining material are not compatible for forming a strong bond, an intermediate layer compatible to both materials may be interposed between the rotor body and lining.
  • the lining may be a preformed insert or may be a layer applied to or formed in the rotor cup.
  • the spinning chamber should be made from materials having good mechanical properties which will resist deformation or rupture when operating at continuous high speeds while being of relatively low specific weight.
  • plastic materials fulfill such requirements quite well.
  • spinning chamber rotors of plastic material are sufficiently lightweight to minimize the power required to drive them.
  • plastic material has the important disadvantage of creating static electricity which has an adverse effect on the tensile strength of the spun thread and in some cases the static electricity is sufiicient to disrupt the spinning process entirely.
  • An additional object is to increase the productivity of a spinning machine over that which can be obtained from spinning machines using conventional spinning chamber rotors.
  • FIGURE 1 is an axial section through a spinning chamber rotor of the present invention, with parts broken away, including associated fiber supply and thread withdrawal means in section.
  • FIGURE 2 is an axial section through a modified spinning chamber rotor with parts broken away.
  • FIGURE 3 is an axial section through a different form 3,439,487 Patented Apr. 22, 1969 of spinning chamber rotor with parts broken away. Loosened fibers are supplied by means of a feeding pipe 2 to the spinning chamber rotor, from which said fibers after forming a fiber ring are finally drawn off through a yarn outlet pipe 3 as a twisted yarn.
  • the rotor body 1 is made of an aluminum alloy while the interior of the cup-shaped spinning chamber has a lining 4 of brass.
  • the relative hardness of a material is not a characteristic quality for material exhibiting beneficial spinning properties because, while brass is relatively soft, chromium, a relatively hard material, has been found to be a suitable lining material for the spinning chamber. This unexpected result may be explained by the fact that the friction characteristics of the lining material influence the deposition of the fiber in the collection channel.
  • plastics which are suitable for the body 1 certain styrol resins can be readily coated with the lining material by electrostatic deposition, for example, ABSpolystyrenes, several of which are sold under the trademarks Novodur PM2C, Cycolac EP 3510 or Terluran KR2540. If desired a plastic rotor body 1 can be strengthened by fiber glass reinforcing strands being embedded in the resin.
  • the particular lining material is selected not only according to its forming and/or bonding qualities, but also according to the particular fiber which it is intended will be spun in the spinning chamber.
  • the coating 4 can be applied to the spinning chamber interior by any suitable method such as by electroplating, spraying, anodizing, japanning, spinning a foil onto the surface, or centrifugal sintering, but preferably is injected into the spinning chamber as a foil.
  • a preformed insert 5 can be set into the spinning chamber.
  • the inner annular wall of the rotor body defining the insert-receiving cavity is cylindrical and the undercut wall of the spinning chamber is formed in the insert 5 only.
  • the insert can be formed by pressing, extruding, deep-drawing using a collapsible die, blow-molding, diecasting, centrifugal casting or laminating, depending upon the type of material of which the insert is made.
  • the rotor insert-receiving cavity may be shrunk after the insert is put in place, or the insert may be adhesively bonded in the rotor cavity.
  • a suitable adhesive is epoxy resin, one of which for example, is sold under the trademark Araldit.
  • an intermediate layer 6, shown in FIGURE 3, of a material which has an atfinity for the lining material can be interposed between such rotor and lining.
  • the lining 4 is then applied to the intermediate layer.
  • Layer 6 can be applied as an intermediate coating, as shown in FIGURE 3, or it could be a preformed insert, such as the insert 5 shown in FIGURE 2.
  • the lining material is preferably a metal or a cermet, but it can also be a nonmetal such as a ceramic or Teflon.
  • the lining can be a single layer or it can be applied in multiple layers, particularly if the lining is a coating electroplated in the cavity of a plastic rotor.
  • a spinning rotor having a body of lightweight form-sustaining material and including an annular wall defining a spinning chamber cavity in one end portion thereof, the cavity wall having a lining of material different from that of the rotor which has good spinning properties.
