Definitions

  • a large number of individual filaments are spun simultaneously to form a tow.
  • This tow is then passed through a crimping device which both crimps the tow and cools the tow to set the crimp therein.
  • the tow may then be sold as tow or cut into staple fiber in a well-known manner, after which the staple fiber is carded and drawn into yarn.
  • the purpose of the crimping operation is to increase resistance to relative movement between the staple fibers in the finished yarn. It is well known that the condition of the tow leaving the crimping device has a great deal to do with the quality and appearance of the yarn.
  • the heated tow is passed between a pair of rollers which force the tow into a chamber commonly referred to as a stutfing box.
  • a pivoted clapper bar mounted at one end of the stufiing box serves to provide a back pressure against which the rollers operate to thereby fully crimp the tow.
  • the clapper bar swings aside and the tow passes out of the stuffing box onto a discharge chute.
  • one of the objects of this invention is to provide a novel and improved discharge chute for a tow crimping device.
  • Another object of this invention is to provide a discharge chute which will uniformly control the back pressure of a crimped tow leaving a stuifing box.
  • Still another object of this invention is to provide a tow crimper discharge chute which ofiers a back pressure to rollers feeding the tow into the chute and which will maintain the configuration of the tow leaving the stufiing box.
  • a further object of this invention is to provide a discharge chute which will receive a crimped tow from a stuffing box without having the tow fold over or depart from the rectangular cross-sectional configuration or" the tow in the stalling box.
  • a still further object of this invention is to provide a tow crimper discharge chute wherein air pressure is utilized to hold the tow in engagement with a wall of the chute to thereby maintain a substantially rectangular cross-sectional configuration in the tow.
  • Still another object of this invention is to provide a tow crimper discharge chute wherein the chute itself rather than a clapper bar is utilized to provide a back pressure for the tow being crimped.
  • One embodiment of this invention contemplates a tow crimper discharge chute wherein a curved chute extends from the lower end of a stuffing box into which the tow is crimped and packed by a pair of crimping rollers.
  • a manifold extending along the chute is provided for drawing air through apertures in the floor of the chute so that until it reaches the free end of the bathe.
  • the tow when the tow leaves the stufling box and enters the chute the tow is held tightly in engagement with the floor of the chute to offer a back pressure to the crimping rollers.
  • the air passing through the tow not only cools and sets the crimp in the tow, but also holds the tow against the floor of the chute so that the tow passing through the chute retains its rectangular cross-sectional configuration.
  • the single FIGURE is a perspective view showing a crimped tow passing through the discharge chute of the present invention.
  • a pair of crimping rollers 11 which force a heated tow 12 into a stufiing box 13.
  • the rollers 11, which are of a conventional design, are rotated at a high speed in a well-known manner so that the tow 12 is crimped and forced into the stuffing box 13, the crimped tow taking on the cross-sectional configuration of the stufling box.
  • the stulfing box 13 is a conventional type with a rectangular cross-sectional configuration. It is not necessary that the conventional clapper bar be used.
  • a chute 14 Extending from the lower end of the stufiing box 13 is a chute 14 which curves from a vertical direction at the stuffing box 13 to a horizontal direction.
  • the tow 12 is crimped and packed into an elongated mass 17 which passes out of the stufiing box 13 onto the chute l4 and along this chute, from which it is picked up in any convenient manner.
  • the flow of air is eiiected by a fan 20 connected by a duct 21 to a chamber 22 communicating with the manifold 18.
  • the apertured area of the floor of the chute 14 extends from the upper end thereof substantially along the length of the chute.
  • a baffie 25 is mounted in the chamber 22.
  • the battle 25 extends completely across the chamber 22 and extends upward at one end to the floor of the chute 14. Air which passes through the apertures 19 above the bafile 25 must flow along the battle toward the arcuate end of the chute 14 In effect, the battle 25 cooperates with the floor of the chute 14 to form an open ended manifold through which air is drawn into the chamber 22, the air passing through the open end.
  • a damper 26 in the duct 21 serves to adjust the rate of air flow.
  • the rolls 11 grasp the heated tow i2 and force it down into the stuffing box 13 at a high rate of speed. Because of this high rate of speed, the tow assumes the rectangular cross-sectional configuration of the stuffing box 13.
  • the mass of crimped tow passes downward out of the stuffing box 13 and onto the floor of the chute 14. Since the fan 20 is withdrawing air through the manifold 18 and the apertures 19 in the chute 14, the mass 17 of crimped tow is held tightly in engagement with the chute 14 to provide a uniform back pressure.
  • the tow is pushed downward along the arcuate portion of the chute and then along the horizontal portion of the chute and is taken off the end of the chute in a well-known manner, the air having set the crimp in the tow as it passed along the chute.
  • this device results in a uniform back pressure and a uniform feeding of the crimped tow from the stufiing box 13 onto the chute 14.
  • the air passing through the crimped tow into the manifold 18 holds the tow against the surface of the chute 14 to prevent buckling or folding of the tow as it passes along the chute.
  • the tow retains its shape, thereby insuring a superior staple fiber. This also makes packaging of the tow easier, since there is less tangling when the tow has a uniform and tightly packed configuration.
  • A. discharge chute for a tow crimping device having a stuffing chamber therebelow comprising a horizontal chute having an arcuate end extending upward to the stuffing chamber, said chute having an apertured floor terminating at the stufiing chamber for engaging a crimped tow emerging from said chamber, a first manifold secured to the arcuate end of the chute in communication with the apertured floor thereof, a chamber secured to the chute beneath the floor thereof and connected to the first manifold, a bafile mounted in the chamber and cooperating with the horizontal portion of the chute to defined an open-ended second manifold, a duct leading from the chamber, a fan connected to the duct for drawing air through the apertured floor of the chute to hold the tow against said fioor, and means in the duct for adjusting the rate of air flow.
  • a tow crimping device comprising a stuffing chamber, a pair of rolls mounted adjacent to the chamber for forcing a tow into the chamber, a chute extending downward from the chamber for engaging the crimped tow leaving said chamber, means for controlling the back pressure on the tow leaving the chamber, said means comprising a plurality of apertures in said chute and means for drawing air through the apertures to hold the tow against the chute.
  • a tow crimping device comprising a stuffing chamer, a pair of rolls mounted adjacent to the chamber for forcing a tow thereinto, a chute extending vertically downward from the chamber, said chute having a curved upper end terminating in a horizontal portion, said chute being positioned to receive the crimped tow leaving the chamber, means for controlling the back pressure on the tow leaving the chamber, said means comprising a manifold secured to the chute, a plurality of apertures in the chute and suction means connected to the manifold for continuously drawing air through the apertures to hold the tow against the chute.
  • a tow crimping device comprising a stuffing chamher, a pair of rolls mounted adjacent to the chamber for forcing a tow thereinto, a chute having a floor aligned with an interior surface of the chamber for receiving crimped tow from the chamber, said floor having a ertical portion adjacent to the chamber and a curved lower end terminating in a horizontal portion, means for controlling the back pressure on the tow leaving the chamber, said means comprising a manifold secured to the lloor of the chute, a plurality of apertures in the floor of the chute, and suction means connected to the manifold for drawing air through the apertures in the floor to hold the tow against said floor.
