Definitions

  • the invention relates to a method and a device for bringing together nonwovens or pile of fibers, in particular textile fibers, in which or in which the pile or the like is placed next to one another and removed together.
  • the object of the invention is to create a pile of wide width consisting of juxtaposed florets of smaller width, in which the non-uniformities at the point of contact, i.e. the longitudinal seam, are balanced to a homogeneous pile.
  • the invention is characterized in that the adjacent sheets are subjected to a compression process known per se and in that the compressed pile of greater width is again drawn out somewhat.
  • the fiber sheet is to be compressed in the running direction or transverse to the running direction so that there is an increased orientation of the fibers perpendicular to the surface of the fiber sheet, which has been fixed by subsequent mechanical and / or chemical treatment.
  • FR-PS 2 110 266 it is known to subject Flore to a stretching process in order to then feed it to a processing machine, for example a card or the like.
  • the pile is stretched in such a way that the pile first is subjected to clamping, followed by stretching by means of rollers or the like.
  • the measure of the invention gives a pile of large pile width, in which the fibers in the ranzones are mechanically connected to one another in such a way that a uniformly uniform pile is formed which corresponds to all the stresses during further processing in this regard.
  • the intermediate upsetting process results in a reorientation of the fibers, in particular along the edge zones of the adjacent or somewhat overlapping pile, so that one can speak of a homogeneous seam zone.
  • the large-width pile represents a uniform web.
  • the fibers are mixed in particular at the edge zones of the adjacent pile by means of the upsetting process. This results in a clawing of the fibers in the edge zones, so that the two adjacent pile form a continuous pile of the same structure.
  • the upsetting process should be relatively strong.
  • An upsetting process with a negative distortion in a range from 25% to 35% is preferred.
  • the delay can preferably be about 30%.
  • the piles can lie against one another on the adjacent edge parts. They can also overlap to a certain extent on the neighboring marginal zones. It is particularly advantageous if the overlap of the piles at the adjacent edge zones takes place by means of an inclined position of the end faces.
  • the claws of the fibers are uniform Railway particularly strong.
  • the merging of the individual piles takes place expediently by means of a device which has a feed drum and then an upsetting device with at least one upsetting roller, the drum and the rollers rotating in opposite directions. After the upsetting device, rollers are arranged at a higher speed than that of the upsetting roller.
  • the upsetting expediently takes place in the range from 25% to 35% and can be carried out by means of an upsetting roller or in stages by means of a plurality of upsetting rollers.
  • the rollers which may be present after the upsetting device can rotate at a higher speed than the rollers or rollers of the upsetting device. As a result, the pile of greater width is essentially brought back to the original thickness.
  • the floras are expediently placed on top of one another in such a way that the end faces of the edge zones — seen in cross section — run in the oblique direction, so that the seam zone itself is given a certain width. This supports the clawing of the fibers within the relatively wide seam zone.
  • the device 1 for producing piles of large pile widths has a conveyor belt 2 which is guided around the deflection rollers 3 and 4. Thereafter, a relatively large drum 5 is provided with a guide roller 6 for the adjacent sheets 7 and 8.
  • an upsetting device 10 which in the present example consists of the upsetting rollers 11 and 12.
  • the total warping of the upsetting device 10 is advantageously in the range between 25% and 35%, preferably about 30% warp compared to the peripheral speed on the drum 5.
  • the peripheral speed of the upsetting device, ie the warping at the upsetting device 10 to the roller 14 is again positive, so that the pile of large pile width is again drawn out somewhat.
  • the pile of large pile width passes from the roller 14 with the aid of a transfer roller 15 to a discharge belt 16 which is guided over the deflection rollers 17 and 18.
  • Rolling is of a normal type, i.e. with usual trimmings, e.g. an all-steel set.
  • the rollers rotate in opposite directions to each other.
  • the homogeneous pile 19 of large pile width can then be fed to further processing machines.
  • the upsetting process means that the layers of the edge zones of the pile interlock more or less in order to obtain a uniformly uniform pile of greater width.
  • This effect can be supported by the fact that the end faces of the edge layers are provided with bevels 21, 22, so that there is a corresponding overlap, as can be seen in FIG. If a plurality of piles 7a, 7b, 7c or 8a, 8b, 8c are used one above the other, it is appropriate to arrange the side surfaces 23, 24 of the superimposed piles somewhat offset from one another so that the surfaces correspond to one another predetermined slope can overlap (Fig. 4).
  • FIG. 5 illustrates a further device for bringing together adjacent floras to form a homogeneous pile of greater width.
  • a conveyor belt 27 and a pile 28, e.g. can consist of three layers to the feed device 29.
  • This can consist of the feed rollers 30, 31, 32, which also includes a further lower roller 33.
  • These pile guide rollers should have no distortion with respect to one another, so that they rotate at the same speed.
  • This is followed by two large drums 34 and 35, which work as an upsetting device. Between the drums 34 and 35 there is a negative distortion in the range from 25% to 35%, whereby the compression effect is achieved.
  • the drum 34 can be on the underside, i.e. be provided with a trough 37 on the pile-free side.
  • a doffing device 38 can then be connected to the upsetting roller 35, after which the pile of greater width can be removed by a conveyor belt 39. It is also possible for a third drum 40 to be arranged, which then adjoins the removal device
  • the feed rollers 30 to 32 are advantageously driven in the same direction, while the drums each have an opposite drive.
  • the sets of rollers and drums are of a common type, It is preferably all-steel fittings. Instead of the illustrated customer device, any other type of customer can also be provided.
