Definitions

  • the present invention relates to yarn texturing wherein yarn is provided with latent crimps by passing through meshed gears, and more particularly to such texturing which is adapted for texturing textile denier yarns.
  • thermoplastic yarns In a known method and apparatus for texturing thermoplastic yarns, as typified by Bromley et al. US. Patent 3,024,516, yarn is simultaneously drawn from a draw pin and crimped by multiple passes through a set of meshed gears in cooperation with a separator roll.
  • the yarns typically processed according to the Bromley et a1.
  • apparatus ranged from nearly a thousand to several thousand total denier.
  • the individual filament deniers were typically sixty denier per filament (DPF) before texturing, and about twenty DPF after texturing. Due to the heavy denier yarns processed in the Bromley et a1. apparatus, several passes of the yarn around the gears were necessary to get enough traction to draw yarn. Since the individual filaments had a large denier, relatively coarse pitched gears and comparatively wide clearance between the gears was necessary, which increased the need for several passes through the gears.
  • DPF sixty denier per filament
  • a primary object of the invention is to provide a method and apparatus for texturing yarn.
  • a further object is to provide such method and apparatus wherein the yarn is textured by a single pass through meshed gears.
  • a further object is to provide such a method and apparatus wherein the geometry is arranged so as to require a minimum number of parts and a simple stringup.
  • the invention accordingly comprises the several steps and the relation of one or more of such steps with respect to each of the others, and the apparatus embodying features of construction, combinations of elements and arr-angements of parts which are adapted to effect such steps, all as exemplified in the following detailed disclosure, and the scope of the invention will be indicated in the claims.
  • FIGURES 1 and 2 are fragmentary schematic perspective views of apparatus according to the invention.
  • yarn 20 from a spin cake 22 or other convenient source is fed by driven nip rolls 24 to a brake or other snubbing device 26, illustrated United States Patent 3,192,597 Patented July 6, 1-965 as an electrically heated hot pin.
  • a conventional guide 27 may be provided to guide yarn 20 to nip rolls 24.
  • Yarn 26 then passes through meshed gears 28 and 30, which are positively driven so as to stretch or draw the yarn in the region between pin 26 and the gears.
  • Yarn 20 then passes through a pigtail guide 32 to a suitable windup mechanism 34, which may be of any desired type.
  • the axis of pin 26 is skewed with respect to the axes of gears 28 and 3t
  • pin 26 lies in the plane in which the gears rotate, and is perpendicular to the path of yarn 20.
  • the filaments of yarn 20 during passage'around the draw pin are formed into a filament sheet, the transverse dimension of which is perpendicular to the axes of the gears. Passage of the yarn as a round bundle or as a filament sheet thus oriented directly through the meshed portion of the gears could result in uneven running and breaking of the filaments by the gear teeth since the gears are closely meshed.
  • gears 28 and 36 are mounted so that the axis along which the yarn travels between pin 26 and the gears forms an acute angle with a perpendicular line between the gear axes, causing yarn 26 to Wrap around part of the periphery of one of the gears in an arc extending over several degrees before contacting the remaining gear.
  • draw pin 26 is so mounted that a line perpendicular to the axes ofgears 28 and 39 forms an angle greater than 10 with the axis of draw pin 26. Since the yarn passes through the meshed portion as a filament sheet, the number of gear teeth per inch of gear circumference may be increased and the clearance between the gears may be reduced. These factors produce suificient traction to draw and crimp the yarn in a single pass through the gears without danger of cutting the filaments.
  • the disclosed apparatus is simple, and provides an economical and reliable process for producing textured yarns.
  • Apparatus for bulking a muiti-filament yarn comprising in combination:
  • said snubbing mechanism being oriented with respect to said gears so that said yarn wraps around part of the periphery of a first of said gears and forms into a substantially flat filament sheet on said periphery before entering into the region where said gears mesh,
  • Apparatus for bulking a multi-iilament yarn comprising in combination:
  • said draw pin being skewed with respect to the axis of said gears sufiiciently .to positively locate the said yarn, and being mounted with respect to said gears so that said yarn wraps around part of the periphery of a first of said gears and forms into a substantially fiat filament sheet on said periphery before entering into the region where said gears mesh.
  • a method for texturing yarn in a single pass through a pair of meshed crimping gears comprising in combination:
  • Yarn treating apparatus comprising in combination:
