Definitions

  • the present invention relates to a method for producing a warpable staple fiber tape, in which a strand consisting of endless, parallel filaments of elongate cross-section is continuously conveyed in its longitudinal direction, cut at intervals at an acute angle to its longitudinal direction and thereby broken down into parallelogram-shaped sections and this strand, which has been broken down into sections, is combined on both sides and compressed and formed into a staple fiber tape of approximately round cross-section.
  • This is characterized in that the region of the staple fiber band along a surface line, along which, when the strand is gathered and compacted, the foremost peaks of the parallelogram-shaped sections come to lie in relation to the staple fiber band movement, is continuously pushed into the interior of the staple fiber band, as a result of which a staple fiber band of approximately kidney-shaped cross section is formed.
  • the present invention also relates to a device for performing the above method with a summarizing and compacting point for a lateral summarizing and compacting of the strand.
  • This device is characterized in that in the web of the staple fiber band in the area in which it has an approximately round cross section. there is a curling roller with a disc which dips into the inside of the staple fiber band in the region of the surface line.
  • FIG. 1 shows interfaces 11 at which a strand 12 consisting of originally endless, parallel filaments, which is continuously conveyed in the direction of arrow 13, is cut.
  • the cutting can take place, for example, by means of knives running helically on a roller, which are not shown in the drawing, since they have nothing to do with the present invention.
  • the strand 12 has an elongated cross section, as shown by the cross section 15 belonging to the location 14. It can be seen that cutting results in parallelogram-shaped sections which are delimited by the interfaces 11 and the side surfaces 16 of the strand 12. It cannot be avoided that, as a result of the cutting, the fiber ends at the interfaces 11 form forward tips 17 protruding laterally from one side surface 16 and rearward tips 18 protruding from the other side surface 16.
  • the strand 12 passes between the endless belts 21, which continuously rotate on rollers 22 in the direction indicated by arrows.
  • the belts 21 move against the side surfaces 16, press them together and compress the strand 12 to form a staple fiber band 23.
  • a staple fiber band 23 of approximately round cross section is produced, as is shown by the cross section 25 present at the point 24.
  • the staple fiber band 23 then runs over a curling roller 26. As shown in FIG. 2, this has a disc 27 which runs into the staple fiber band in the region of an imaginary surface line of the staple fiber band 23, which runs parallel to the latter at the points of the tips 17 23 immersed. As a result, this area is pushed into the middle of the staple fiber band 23, whereby its structure changes as shown by the cross section 32 present at the point 31. This is of kidney-shaped shape, the tips 17 now being in the middle of the staple fiber band 23.
  • the conveyor rollers 33 move the staple fiber belt 23 further.
  • a guide wall 34 can be provided on both sides of the disk 27, as indicated in FIG. 2. For reasons of clarity, this guide wall 34 is not shown in FIG. 1.
  • the guide walls 34 each form a trough-like depression 39 with the disk 27.
  • FIG. 3 Another form of guide walls can be seen in FIG. 3.
  • the curling roller 35 each has a roller 36 attached to the side of the curling disc 27, each of which forms a guide wall, the purpose of which is to keep the cross section of the staple fiber band 23 round and compact.
  • the immediately adjacent side walls of the curling disc 27 and one roller 36 converge in the direction against the axis of rotation 37 and merge into one another, so that there is a trough 38 surrounding the curling roller 35 on both sides of the disc 27.
  • Fig. 1 the kink is shown. It consists in that the direction of the staple fiber strip running away from the curling roller 26 deviates somewhat from that of the one running towards the roller 26.
  • the angle formed by the two parts of the staple fiber band 23 is less than 180 ° and is advantageously between 150 ° and 170 °.
