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 elongated cross section is continuously conveyed in its longitudinal direction, cut at intervals at an acute angle to its longitudinal direction and thereby in parallel. Lelogram-shaped sections are disassembled and this strand, which has been disassembled into sections, is combined and compressed on both sides and formed into a staple fiber band of approximately round cross-section.
- This is characterized in that the area of the staple fiber tape is continuously inserted into the inside of the tape along a surface line, along which, when the strand is combined and compacted, which come to lie at the forefront of the parallelogram-shaped sections in relation to the tape weaving, whereby a staple fiber tape of approximately kidney-shaped cross section is formed.
- the present invention also relates to a device for carrying out the above method with a merging and compacting point for a lateral merging and compacting of the strand.
- This device is characterized in that in the web of the staple fiber tape of approximately round cross-section there is a curling roller with a disk which plunges into the staple fiber tape in the area of the jacket line into the interior thereof.
- Fig. 3 shows another embodiment of this roller.
- 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 position 14. It can be seen that the 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 tapes 21 move against the side surfaces 16, press them together and compress the strand 12 to form a staple fiber tape 23.
- a tape 23 of approximately is formed round cross-section, as shown by the cross-section 25 present at point 24.
- the tips 18 directed rearward in relation to the direction of the arrow 13 have practically no disadvantageous consequences.
- the forward tips 17 cause the difficulties already mentioned in the further treatment of the staple fiber band 23. They remain during the summarization and compression process as they pass through the belts 21.
- these parts are to be avoided by having the area of the serband 23 along its imaginary surface line which runs through the foremost points 17 of the parallelogram-shaped sections 11, 16 with respect to the direction of the arrow 13 brings the middle of the band 23 in.
- the structure already mentioned, shown by the cross section 32 results for the latter.
- the forward ones Tips 17 have been embedded in the middle of the band 23. There they are made completely harmless during further processing, ie embedded in the other fibers.
- the disk 27 is rounded in the area of its largest circumference and thickens against its axis of rotation 37.
- the disc may be fixed depending on a guide wall 34 be provided 27, as is indicated in Fig. 2 on both sides. 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 belt 23 round and compact.
- the immediately adjacent side walls of the rolling-in disc 27 and one roller 36 each converge in the direction against the rotation axis 37 and merge into one another, so that there is a trough 38 running around the rolling-in roller 35 on both sides of the disc 27.
- Fig. 1 the kink is shown. It consists in that the direction of the strip running away from the curling roller 26 deviates from that of the sth running towards the roller 26.
- the angle formed by the two parts of the staple fiber band is less than 180 and is advantageously between 150 and 170.
