Definitions

  • the improved apparatus described in said British patent specification generally comprises a suction tube fitted near to the receiving package, and on the opposite side of such package from the source of the yarn or filament. At the outset of the collecting operation the yarn or filament is passed into the tube.
  • stable operating conditions i.e., when the yarn or filament at the receiving package is uniform, the yarn or filament is brought-either manually or by means of an entrainiment deviceinto contact with the receiving package.
  • the yarn or filament is then severed or broken, the severed length thereof being deposited in a waste collection box, and the succeeding yarn or filament passing from the source is collected continuously on the bobbin or other receiving package.
  • Non-return suction guns through which the yarn can pass in one direction only, have been tried in order to overcome the difficulties caused by the yarns being drawn back onto the spindle whorl, but the entrainment operation then becomes rather uncertain since the nonreversal characteristics cause a severe snatch at entrainment and may cause the yarn to break before properly entrained.
  • a yarn or filament is collected continuously on a receiving package by means of a suction tube fitted near to the receiving package and on that side of the package distant from the source of the yarn or filament.
  • the yarn or filament is passed into this tube until stable operating conditions are attained, when'it is brought into contact with the receiving package.
  • the delivery end of the suction tube leads substantially tangentially into a chamber of right cylindrical section, which has an outlet tube olfset to the suction tube and leading from the chamber.
  • a yarn cutting means is located within said chamber .at the end of the suction tube.
  • the guide located withinthe-charnber so that when the yarn forms a loop in the chamber the-loop of-yarn encloses the guide.
  • the guide should comprise a cylinder around the outside of which is a spiral groove, said cylinder having a sliding fit within the chamber.
  • Figure 1 is a partially diagrammatic view of a yarn collection apparatus according to the instant invention
  • Fig. 2 represents an enlarged side elevation view, rotated 90, of the apparatus seen at the lower right in Fig. 1, with the chamber in section to show the guide therein
  • Fig. 3 is a section through line 3-3 of Fig. 2.
  • yarn 6 is shown passing in the direction of the arrow through a guide 10 from a source (not shown), such as a drawing or heat treating apparatus, to a collection device, illustratively a bobbin 12 keyed in the usual manner to a spindle 14.
  • a source such as a drawing or heat treating apparatus
  • An entrainment disc 20 is provided at the lower end of bobbin 12. The yarn 6 passes through the traveler 16 of the ring 18,
  • a closed cylindrical chamber 3, best seen in Figures 2 and 3, is mounted beneath suction tube 1.
  • This tube and a second tube 2 project into chamber 3 and said tubes lie in separate planes perpendicular to the axis of the chamber.
  • the tube 1 enters the chamber 3 substantially tangentially.
  • a cylindrical guide 4 with a spiral groove 5 fits within the chamber and extends from the end of the chamber near tube 2 to the edge of the tube 1.
  • the spiral groove 5 terminates at the entrance to tube 2 from the chamber 3.
  • a length of yarn 6 is shown passing through the apparatus, the arrow heads indicating the direction of yarn movement before entrainment takes place.
  • a cutting edge 7 is ground on the mouth of the tube 1.
  • the end of tube 1 protruding from the chamber is attached to or integral with the delivery end of an air air stream and yarn pass into spiral groove 5, and leave via Patented Oct. -11,' 1960 a receiving. package for collecting the yarn when stable conditions are attained and an air-suction tube through which the yarn is passed until stable conditions are attained, the suction tube being mounted adjacent the package on the side thereof distant from the source of yarn;
  • a generally cylindrical chamber having two openings therein, the delivery end of said suction tube communicating with the chamber through one of said openings, an outlet tube communicating with the chamber through the other of said openings, said tubes being relatively ofiset and the suction tube entering the chamber substantially tangentially so that yarn conveyed by the air passing through the chamber from the suction tube to the outlet tube makes at least one loop in the chamber, and a yarncutting means located within said chamber.
