Definitions

  • This invention relates to the handling of thread, yarn and the like in the course of its fabrication into cloth. More particularly, this invention concems a method and an apparatus for avoiding the occurrence of irregularities in highly twisted rayon thread during the course of unwinding from a supply package on a fabricating machine such as f full-fashioned hosiery machines.
  • the thread delivered overhead from supply cones is directed by way of various guiding'andtension devices to the knitting mechanism by which it is laid in flat courses to form the body oi the hose, and the length of the course which the thread travels depends upon the width of the fabric to be knitted.
  • the thread be maintained under uniform tension while it is being knitted.
  • the present invention is designed to overcome these diiliculties and has for its object the provision of a method and apparatus for inhibiting the kinking of highly twisted thread adjacent the supply package when the withdrawal of thread therefrom is momentarily stopped.
  • the invention contemplates the provision of an apron oi pliable, light-weight cloth or other suitable material, de:- signed to drape over and substantially cover, a supply package, such as a cone.
  • apron falls loosely about the cone, contacts the outer coils of thread thereon, holds them in place and inhibits the introduction of slack in the thread when withdrawal from the cone is momentarily stopped.
  • Figure 2 is a plan view of the apron showing the eyelet through which thread is withdrawn from the cone;
  • Figure 3 is an enlarged view in perspective of the grommet or eyelet through which the thread is withdrawn from the cone;
  • Figure 4 illustrates in perspective a modified form of the invention wherein a standard'is employed to support the apron.
  • a package of thread I, cross-wound upon a conical core 2 rests upon a pad 3 of felt or other suitable material.
  • Thread 4 is withdrawn overhead from package I and is directed by way of guides and tensioning devices, not shown, to a fabricating machine such as a fullf ashoned knitting machine, also not shown.
  • a fabricating machine such as a fullf ashoned knitting machine, also not shown.
  • slack is introduced in the thread 4 between the supply package and the iirst de vice employed vfor placing the thread under tension.
  • an apron 5 preferably made of pliable, light-weight cloth such as rayon net, is provided, the general shape of which is circular, as shown in Figure 2.
  • 'I'he center of the apron is provided with an opening 6 in which is aixed an eyelet or gommet l made of metal or other suitable material and comprising a hollow cylindrical portion 8 and anges-S, and I0.
  • a method of inhibiting kink-ing of highly twisted thread in the Youter layers fV a supply package maintained stationary ywhen the thread is withdrawn progressively fromthe outside to the inside of the package during the unwinding operation which comprises placing suilicient tension on the outside layers of thread prior to, and
  • a device for inhibitgressively in contact with the outer layers oi.
  • eyelet 'l is then led by way of guides and tension devices to the knitting machine.
  • theapron is supported by a standard made from a single strip of metal and comprising a 'base il, and an upright portion l2 having its upper end bent to form a hook I3 adapted for insertion 'a knitting machine and fabric made therefrom without danger of breaking machine parts or the appearance of defects in the knitted material as a result of kinks occurring in the thread vbetween the supply package and the first pretension device.
  • a device for inhibiting the introduction of slack in a thread adiacent a stationary supply package during unwinding from the outside to the inside thereof comprising an apron adapted to contact the outer surface of said supply package and an opening. in said apron forthe free passageofthread therethrough.k
  • a device for inhibiting the introduction of slack in a thread adjacent a stationary supply package which decreases in diameter during unwinding from the outside to the inside thereof.
  • apron adapted to contact the outer v surface of said supply package, said apron having an opening therein for the free e of thread rst means denning an opening through which the thread can be withdrawn.
  • a device for inhibiting kinking of highly twisted thread during cessation oi' withdrawal of the thread from the package which comprises collapsible means supported by, and constantly, progressively in contact with, the outer layers of thread of said package and means carried by said collapsible means dening an opening through which the thread can be withdrawn.
  • a device for inhibiting kinking of highly twisted thread during cessation of withdrawal of the .ing kinkilig of highly twisted thread during cessation of withdrawal of the thread from the package which comprises collapsible means constantly, progressively in contact with the outer layers of thread of said package, means carried by said collapsible means defining an opening' through which the thread can be withdrawn and separate means adapted to engage said second means for supporting said collapsible means in operative position.
  • a'devlce for inhibiting k'lnking oi' highly twisted thread during cessation of withdrawal oi the thread from the spool which comprises a col-l lapsible apron constantly, progressively in con- 'tact with the outer layers of thread ofsaid package.
