Definitions

  • This invention relates to winding or takeup apparatus; and more particularly to such apparatus which provides a yarn or thread reserve on a new bobbin, for example, and then permits normal takeup on the bobbin with a minimum of manual control.
  • our novel apparatus for the formation of a thread reserve on a thread winding or takeup device while the thread advances towards such device comprises: thread guide means positioned in advance of the takeup device as viewed in respect of the direction of the advancing thread, the guide bar having a lower surface substantially parallel to the longitudinal axis of the takeup device and extending across the winding or takeup range thereof, and a second surface merging with the lower surface and positioned in advance of a reserve range of the takeup device, and switch means adjustably positioned relatively to the guide means for maintaining the thread in the range of the second surface and adapted to release same from that range.
  • FIGURE is a perspective view illustrating an embodiment of our invention in operative position relative to a winding or takeup device.
  • the guide bar I is shown as comprising an upper flat rigid surface 2 and a lower flat rigid surface 4 merging with a curved, generally inverted U-shaped surface 5.
  • the guide bar 1 may conveniently be formed of a synthetic plastic material or a suitable metal.
  • a flat switching lever 6 formed with a finger plate 7 is pivotally mounted to the guide bar by a rivet 8; and the guide bar itself is mounted on an angle bar 9 by means of screws 10 such that the lower surface 4 lies substantially in the same plane,as a transverse thread guide 11 and that the thread 12, while advancing in the range of the surface 4 passes to the winding range 14 of a bobbin 15. It will be seen that in this position, the thread, when advancing in the range of the curved surface 5 of the guide bar passes to the reserve range 16 of the bobbin.
  • the switching lever 6 is formed with a straight edge 17 adjacent the curved surface 5,0f the guided bar, and the finger plate 7 is preferably positioned on the side of the rivet 8 opposite the edge 17.
  • the lower edge 18 of the switching lever is inclined upwardly and to the right as viewed in the thread-advancing direction so that its plane intersects the plane of the edge 4.
  • the rivet 8 is so positioned relatively to the center of gravity of the lever 6 that the latter tends normally to assume the position shown, its pivotal movement being limited by a pin 19 fixed to the lever and extending into an arcuate groove 20 in the bar 1.
  • a wound bobbin is removed from contact with the drive shaft 21 and lifted from the bobbin support 22 by sliding its axle 24 upwardly in the support guide grooves 25.
  • the thread 12 is necessarily removed from the thread guide 11.
  • the thread 12 is then laid into a hook (not shown) fixed to the front of the machine to maintain tension, and is manually guided along the lower edge 18 of the switch 6 from the guide bar surface 4 to the curved surface 5.
  • the reserve range of the new or empty bobbin is then placed into contact with the thread and is lowered into the bobbin support 22 by sliding the axle 24 down into the grooves 25.
  • the reserve thread commences to be wound on the bobbin when the bobbin contacts the rotating drive shaft 21 and the thread is automatically torn off the U-shaped hook (not shown).
  • the edge l70f the switch lever confines the thread in the range of the curved surface until sufficient reserve thread is wound on the bobbin.
  • the finger plate 7 is then depressed to pivot the switch lever 6 in a clockwise direction as viewed, thereby to release the thread from the range of the curved surface 5 of the bar 1.
  • the apparatus of the present invention materially reduces the number of manual operations necessary to change a bobbin and provide for a thread reserve while permitting rapid changeover with practically no thread loss.
  • Apparatus for the formation of a threaded reserve on a thread-winding or takeup device while the thread advances towards such device comprising: thread guide mans positioned in advance of the takeup device as viewed in respect of the direction of the advancing thread, said guide means having a lower surface substantially parallel to the longitudinal axis of the takeup device and extending across the winding or takeup range thereof, and a second curved surface merging with said lower surface and positioned in advance of a reserve range of said takeup device and switch means adjustably positioned by a pivot relatively to said guide means for maintaining the thread in the' range of said second surface and adapted to release same from that range, the axis of the pivot by which said switch means is mounted being so located that said thread confining edge of said switch means is normally held by gravity in confining position and said lever may be pivoted to shift said edge away from said position.
  • Apparatus for the formation of a thread reserve on a thread-winding or takeup device while the thread advances towards such device comprising; thread guide means positioned in advance of the takeup device as viewed in respect of the direction of the advancing thread, said guide means having a lower surfacesubstantially parallel to the longitudinal axis of the takeup device and extending across the winding or takeup range thereof, and a second surface merging with said lower surface and positioned in advance of a reserve range of said takeup device, and switch means pivotally mounted on said guide means and formed with an edge for maintaining the thread in the range of said second surface and adapted to release same from that range upon pivotal movement thereof in one direction, said switch means having a second edge for urging the thread into the range of the lower surface and the winding range ofthe takeupdevice upon pivotal movement in a second direction.
