Definitions

  • the present invention relates to a sliver guide for guiding a plurality of slivers in an entrance area of a track, comprising a first guide section for guiding a first group of slivers, with a second guide section for separately guiding a second group of slivers, wherein the first guide section and the second guide section in FIG a side view of the tape guide are spaced from each other.
  • a route is proposed with at least one entry area for fiber slivers to be drawn and with at least one drafting system comprising a plurality of drafting rollers, wherein in at least one entrance area a first guide section is arranged to guide a first group of slivers, wherein in said entry area second guide portion for separately guiding a second group of fiber ribbons is arranged, and wherein the first guide portion and the second guide portion are spaced apart in a side view of the distance.
  • Stretching is primarily used to produce as uniform a fiber fleece as possible from a plurality of fiber ribbons.
  • the track has one or more draw frames, which in turn comprise a number of default members, usually in the form of a plurality of successively arranged pairs of rollers, wherein the slivers are guided between the respective roller pairs by clamping. Since the pairs of rollers have different and in the direction of tape travel increasing peripheral speeds, the slivers are finally stretched and thereby evened.
  • a band leader placed, for example, a plurality of vertically extending rods, between which the individual slivers are guided.
  • the DE 41 42 038 A1 describes a path for warping a plurality of slivers.
  • the line comprises draw-in cylinders for the common supply of the slivers to the drafting system and a funnel with a passage opening for the union of the slivers to form a fiber composite during the passage of the slivers through the funnel. It is further provided that the cross-sectional area of the passage opening of the funnel is variable such that the funnel regardless of the number of processed fiber slivers achieves a uniform density of the sliver after the funnel.
  • the fiber fleece leaving the stretch usually also has a quality which fluctuates over its width, since thorough mixing of the fiber ribbons takes place only to a limited extent within the stretch.
  • Object of the present invention is therefore to propose a band leader or a route that allow the drawing of slivers of different quality, the production of a non-woven fabric, which is characterized by a high degree of homogeneity.

  • the third guide section preferably serves to guide all the fiber slivers fed to the drafting system after passing through the first and second guide sections.
  • the band guide is designed to first cause a separation of the supplied slivers in two groups, which are guided separately from the two first guide sections, the slivers reunited after passing these guide sections and before entering the drafting by the third Guide section are performed. Finally, it can be determined by the lateral guidance how closely the individual fiber ribbons pass through the respective guide sections.
  • the mutual distance between the two guide elements of the third guide section is set only slightly larger or smaller than the mutual distance of the guide elements of the first and / or second guide section.
  • overlapping of the individual slivers in the region of the third guide section inevitably occurs, so that the slivers are already superimposed before entering the drafting system and a kind of mixing of the individual slivers takes place.
  • the setting of said distance allows a simple way to adjust the band guide to different slivers or different numbers of slivers, in particular, the distance between the guide elements of the third guide portion should be selected so that its amount is smaller than the total width all slivers. This will eventually ensure that there is a certain overlap or overlap of the slivers and thus the desired mixing of the individual slivers.
  • the band guide has a fourth guide portion which is spaced in the said side view of the first, the second and the third guide portion, wherein the fourth guide portion preferably also lateral guide elements for the lateral guidance of slivers are assigned, the mutual distance preferably adjustable is.
  • the fourth guide section is preferably arranged on the side of the second and / or third guide section facing away from the first guide section.
  • the fourth guide portion serves to guide all of the slivers fed to the sliver guide before they enter the region of the first and second guide portions where they are split into the said two groups.
  • the said guide portions are aligned in a side view of the tape guide such that they are located on the corners of a rhombus, wherein the first guide portion of the second guide portion and the third guide portion should oppose the fourth guide portion.
