Definitions

  • ABSTRACT lA curling sleeve forproducing false twist on thermoplastic lfilament passed through the sleeve, the latter having friction rings at one or both ends, and the sleeve constituting the rotor of an electric motor.
  • An object of the present invention is to provide a sleeve and drive therefor which eliminates the drawbacks mentioned above.
  • a curling sleeve according to the invention is characterized in that the sleeve has been designed so as to constitute the rotor of an electric motor. Using a curling sleeve according to the invention, a great advantage is gained in that the number of moving parts is reduced to minimum since the sleeve consists of the rotor proper of the motor used as a drive unit.
  • FIG. 1 is an axial section of a curling sleeve designed so as to constitute the rotor of an electric motor
  • FIG. 2 is another embodiment, shown in axial section along the line 11-11 in FIG. 3, and
  • FIG. 3 is a section taken along line III-III in FIG. 2.
  • the reference numeral 1 indicates the filament to be curled, which passes under guidance by the thread guides 5 through a sleeve comprising a rotor 3 with friction rings 2 at its ends.
  • the reference numeral 6 indicates slide bearings, 7 indicates a body tube, and 8 indicates the stator.
  • the rotor 3 revolves at about -30,000 r.p.m. and the filament 1, which has been heated in an oven, rolls along its inner surface owing to friction. Irregular twist and curls are formed on the filament.
  • FIG. 2 another embodiment of the invention is shown, the slide bearings having been replaced with three pairs of rollers 4, which contact the outer circumference of the rotor.
  • the shafts 9 of the roller pairs 4 have been journaled in tubes 11 fixed to the body 10.
  • One roller or all the rollers may engage in a groove provided by milling on the rotor 3, whereby the rotor will be positiviely positioned in the axial direction.
  • the stator of the motor is laterally confined between the pairs of rollers and radially confined between the rotor body and the journals thereby providing a compact construction.
  • a curling sleeve for ends false twist in a thermoplastic filament passed through the sleeve comprising a rotor body constituted as the rotor of an electric motor, said rotor body having opposite ends and friction rings at said ends, a fixed body, and bearing means for the rotor body supported by the fixed body, said bearing means comprising a plurality of rollers at each of the end of the rotor body, and journals supported by the fixed body and connecting the rollers at the two ends in pairs.
  • a sleeve as claimed in claim 1 comprising tubes secured to said fixed body and rotatably receiving said journals.
