Definitions

  • the invention relates to a method for the automatic separation of Roving when removing bobbins on a roving machine, with suppliers of the roving up to a press finger bed and separating the roving between the press finger platform and the coil circumference.
  • the object of the present invention is a method to create the type mentioned, in which the roving end is fixed on the spool, and the roving is then separated such that a roving piece of predetermined length remains on the press finger platform.
  • This object is achieved by the method step that after unwinding the Vorgamreserve by turning back the spool and lowering the Press finger bed along the bobbin axis, with the roving at the bottom of the upper turn cone rolls to form (false) rotation and its rotation is reduced in the area between the rolled edge and the press finger platform and before pulling the roving apart in the area of reduced twist Press finger bed is moved a distance along the coil circumference, whereby the roving is rolled between the press finger platform and the bobbin circumference and rotated is provided, which propagates in a portion of the area of reduced rotation.
  • the point of separation of the roving can therefore be determined by the distance over which the press finger box pulled over the coil circumference and thereby the Specify the rolled roving (again) given rotation very precisely. With that too the lengths of the roving ends on the spool and on the press finger platform are very precise adjustable.
  • Figures 1 to 4 show a roving bobbin in a schematic side view in different phases in the automatic separation of roving in a defined Area.
  • a work station of a roving machine is schematic Shown side view, a roving spool 1 on a rotatable stored roving sleeve 3 is wound.
  • a roving 2 does not run over one Wing bench shown in more detail through a wing to a press finger platform 10 and is wound on the roving tube 3.
  • the roving reserve of A to D by turning coil 1 back and lowering the press finger platform unwound again along the coil axis. While the roving 2 here on rolls down the lower edge of the upper winding cone B, a false wire is formed, which increases the number of turns per length in section A to B and in section B to D is reduced.
  • the length of the distance D to E is chosen so that sufficient There are rotations per length in section E to C.
  • the press finger platform 10 is in the next step moved to point F on the roving spool 1. With this movement it becomes Roving 2 separated exactly in the area of the previously created weak point C. (Fig.4).
  • the advantage of this method according to the invention also exists, among other things in that the vulnerability in area C with high certainty in the aforementioned Part is generated and one end after separating the roving 2 with the desired length C-D remains on the press finger platform 10. hereby there is a significant improvement in the production process and automatic separation of the roving 2 when pulling a bobbin 1 on Roving.
