Definitions

  • ABSTRACT Improved closure means for the threading slot of a balloon restrainer device in a textile yarn processing machine, such as a twister or the like, which includes a spindle assembly for carrying a package of yarn to be withdrawn and processed and which produces a rotating balloon of the yarn around the package as it is withdrawn therefrom.
  • the improved closure means comprise resilient means secured to the outside surface of the balloon restrainer and spanning the threading slot for resiliently closing the threading slot from the outside thereof during yarn processing operations for allowing the formation of a cushioning column of air within the threading slot from the inside of the balloon restrainer for preventing the escape of rotating air produced by the rotating balloon of yarn through the threading slot and thereby eliminating undesirable noise and which allows the opening of the slot during yarn threading for movement of the yarn there through.
  • This invention relates to improved means for closing the threading slot of a balloon restrainer device utilized in a spindle assembly of a textile yarn processing machine, such as a twister or the like.
  • spindle assemblies are utilized each of which includes a carrier mechanism for carrying a package of textile yarn to be withdrawn and twisted, a rotor mechanism for receiving the yarn from the package and for twisting the yarn as it is withdrawn from the package while forming a balloon of the withdrawn yarn around the package.
  • These spindle assemblies also each normally includes a hollow balloon restrainer device surrounding the package of yarn and theballoon of yarn produced so as to limit the size of the balloon of yarn.
  • the above-described threading slots in the balloon restrainer devices present certain problems inasmuch as the rotating balloons of yarn produced within the balloon restrainer devices during the twisting operations create rotating masses of air within the balloon restrainer devices which escape through the threading slots and cause undesirable noise and other problems from the spindle assembly.
  • the noise factor is particularly acute when it is considered that a typical textile yarn twister machine includes many of the abovedescribed spindle assemblies.
  • closure means for the threading slots of balloon restrainer devices of textile yarn processing machines have been previously proposed, all of these closure means have been unsatisfactory from the standpoint of their failure to eliminate sufficient leakage or emission of air from the interior of the balloon restrainer devices and thereby satisfactorily eiliminate undesirable noise and/or from the standpoint of complexity of construction, undue expense, complexity of operation, etc.
  • Many of the previously proposed threading slot closure means for balloon restrainer devices required complex balloon restrainer device constructions and flexible walls therefor which are undesirable.
  • These previously proposed closure devices normally required mechanical operation for opening and closing of the threading slotwhich is also undesirable.
  • a textile yarn processing machine such as a twister or the like, having a spindle assembly for carrying a package of yarn to be withdrawn and processed and which produces a rotating balloon of the yarn around the package as it is withdrawn therefrom and which includes hollow balloon restraining means surrounding the package of yarn and the balloon of yarn produced so as to limit the size of the balloon of yarn and having a longitudinally extending, radial slot therein for threading of the yarn internally of the balloon restrainer means prior to yarn processing, the following improvement.
  • FIG. 1 is perspective view of a spindle assembly station of a textile twister machine utilizing the improvements of this invention

  • FIGS. 4-9 are sectional views, like FIG. 3, illustrating various modified forms of the closure means.
  • FIG. 1 one spindle assembly station of a textile yarn two-for-one twister mechanism is illustrated in FIG. 1. It is to be understood that a number of these spindle assembly stations are included in each twister machine.
  • the spindle assembly utilized in the spindle assembly station of FIG. 1 and also illustrated in FIG. 2, generally comprises a rotatably driven rotor mechanism, generally indicated at 11, which includes a whorl l2 suitably rotatably mounted on the twister frame 13 and rotated by a continuous belt drive 14 including pivotally mounted roll mechanism 15 in a manner well-known to those with ordinary skill in the art.
  • the spindle assembly 10 further includes a carrier mechanism 18 for carrying a package P or yarn Y and being rotatably mounted on the rotor mechanism 11 so that the rotor mechanism may rotate relative thereto.
  • the carrier mechanism includes a basket device 19 which surrounds the package P of yarn Y.
  • yarn Y is withdrawn from the package P and is threaded through the various mechanisms for twisting or processing of the yarn which results in the formation of a balloon of yarn around the package and around the basket device 19.
  • a hollow balloon restrainer mechanism 22 is mounted around the above-described mechanisms of the spindle assembly 10 and around the rotating balloon of yarn, as shown in FIG. 1.
  • the yarn Y is led from the spindle assembly 10 through a pigtail guide 24,
  • a package roll 27 carrying a suitable bobbin or carrier for receiving the traversely wound yarn Y after it has been twisted or processed.
  • the package roll 27 is rotated by a drive roll 28 in a manner well-known to those of ordinary skill in the art.
  • the yarn Y For starting up of the above-described yarn processing or twisting operation, the yarn Y must be pulled from the package P and threaded through the various devices of the spindle assembly including threading of the yarn Y internally of the balloon restrainer device 22.
  • a resilient closure means For purposes of eliminating this undesirable emission or leakage of air from the interior of the balloon restrainer device 22 during operation of the twister or yarn processing machine, a resilient closure means, generally indicated at 40, has been proposed by this invention.
  • This resilient closure means 40 is secured in a manner described below to the outside surface of the balloon restrainer device 22 and spans the threading slot 30 for resiliently closing the threading slot from the outside thereof during yarn twisting.
  • the flexible closure means 40 may be secured to the outside surface of the balloon restrainer device 22 by the use of shoulder members 44 and 45 suitably secured to the outside surface of the balloon restrainer device 22 and extending along each side of each edge of the radial threading slot 30.
  • shoulder portions 44 and 45 include slots 46 and 47 extending transversely inwardly thereof at the point in which the shoulder portions 44 and 45 are secured to the balloon restrainer device 22 and which extend longitudinally of the shoulder portions 44 and 45 along each side or edge of the threading slot 30.
  • the flexible closure means 40 comprises a pair of resilient strips 50 and 51.
  • the resilient strips 50 or 51 may be constructed of rubber, plastic or other suitable resilient material.
  • the strips 50 and 51 have one longitudinal edge of each secured within the slots 46 and 47 of the shoulder portions 44 and 45 adjacent respective edges of the threading slot 30 and have the other free edge thereof bent back upon itself and also secured within the slots 46 and 47 to form hollow abutting portions which abutt each other generally medially of the threading slot 30.
  • This arrangement increases the surfaces of the strips 50 and 51 which are in abutting relation with each other.
  • Suitable bracket and plate members 52 and 53 are utilized at the ends of the strips 50 and 51 and shoulder portions 44 and 45 for holding the strip members 50 and 51.
