Definitions

  • the invention relates to a method for producing a patterned textile needle felt velor web according to the preamble of claim 1. Such a method is known from US-A-4 047 269.
  • This document describes a method in which staple fibers are placed on a carrier web with the aid of blowing nozzles which are moved in accordance with a pattern to be formed, which are then connected to the carrier web by needling, the fibers differing in color from those distinguish the carrier web, are pushed through to the underside of the carrier web, which lies on a support and later forms the top of the material web in use.
  • the base is formed by a plate with holes or slots through which the needles can pass during the needle operation. Those fibers laid on by the air flow, which were seized by the needles during the needling process, are then suctioned off, and then another needling is carried out in order to solidify the material web.
  • CH-A-401 893 discloses three different methods for producing a patterned needle composite.
  • prefabricated surface patterns are applied in a specific arrangement to the visible side of a flat structure and connected to it by a needle process.
  • a second sheet-like structure is placed on a sheet-like structure and connected to the first sheet-like structure by needling in such a way that the fibrous structures pierced in a predetermined arrangement result in the desired pattern on the back of the same.
  • fibrous structures such as slivers, applied to a sheet-like structure and connected to it by needling. The manner in which the carrier web is supported during the needle operation is not described.
  • a system for the production of structured textiles with velor needle felt webs which consists of a mechanically or aerodynamically operating fleece laying machine, a pre-needle machine and a velor needle machine, in which at least the velor needle machine with one of the fleece to be needled carrying and serving as a stitch pad endless brush tape, which is composed of a plurality of brush plates carrying the tufts of bristles. Crown needles are used for the three-dimensional structuring of the pre-needled fiber fleece.
  • the invention has for its object to provide a method with which it is possible in a simple manner with the least possible outlay on equipment to produce versatile and also differently patterned textile nonwoven velor webs.
  • Crown needles are preferably used to produce the structured carrier web.
  • fork needles can also be used instead of the crown needles or in addition to the crown needles if the desired structuring of the carrier web requires this.
  • the structuring needle unit is expediently equipped with two parallel needle bars that work either synchronously or asynchronously according to a certain program. It is also possible to switch off the needle bar fully equipped with fork needles.
  • the carrier web can be produced from a wide variety of primary materials, either from a pre-needled non-woven fabric or a pre-needled non-woven fabric with fibers oriented essentially in the longitudinal or transverse direction of the web.
  • the primary material can be single or multiple layers. It is also possible for the individual layers to contain fibers which are oriented in very specific directions within the web. Such materials are produced in a manner known per se with the aid of machines or apparatus known per se.
  • the application of the fiber material required for the patterning of the needle felt or nonwoven webs can be done by placing a further web of fiber material over the entire surface or in strip form on the carrier web and then further treating it, as already indicated. Instead of large-area or strip-shaped nonwoven webs, it is also possible, depending on the desired pattern, to place a large number of flat sections of a nonwoven web of fiber with the desired geometric shape on the carrier web.
  • the fibers in the nonwovens or their sections which are applied to the carrier web have an orientation which is transverse to the main orientation of the fibers in the carrier web.
  • the fibers effecting the pattern are optimally grasped by the fork needles and pressed through the carrier web on the underside thereof, which is later the top side of the end product.
  • a brush tape with a surface that is as homogeneous as possible and formed by the tips of the bristles is used as a base for the material web for the purpose of processing it during all process steps, so that the best possible support of the material web is carried out.
  • a brush belt has become known from DE-OS 34 44 763. It has already proven itself in practice and is therefore also ideally suited for the method under consideration here, since there are no gaps or spots in the surface of the brush strip with a smaller or denser bristle population.
  • the preliminary product or products which have been formed to form the nonwoven web for the purpose of structuring it can be stretched in a manner known per se depending on the orientation of the fibers contained in the nonwoven or in other directions. This method is known per se and therefore requires no further explanation.
  • fork needles are used for the final needling of the material web to produce the end product, in which the planes in which the forks are located lie transversely to the direction of the fibers which are pushed through the carrier web in the form of pile loops by the forks should.
  • crown needles or optionally other shaped needles can also be used in addition to the fork needles.
  • the needles used here in groups are attached to one or more needle bars that can be moved up and down, the individual needle bars together in time and synchronously or else asynchronously with one another or also individually and are independently movable. Decisive for the movement of the individual Needle bar is especially the desired pattern. It is important here to change the distance of the needles relative to the plane of the fleece to be needled or the support surface of the carrier web during operation in the last needling stage, depending on the pattern to be generated.
  • the needle units and / or the carrier web can be adjusted mechanically or electrically or also hydraulically in the manner specified above.
  • the needle bars are not filled with needles over their entire width, but only in places or areas, so that there are practically no limits to the variety of patterns that can be generated.

  1. Procédé pour fabriquer une bande textile aiguilletée de velours feutré, à partir d'une bande porteuse en matière textile et d'une matière fibreuse textile qui diffère des fibres de la bande porteuse quant à la teinte et/ou la forme et/ou la matière et/ou le degré de finesse et/ou l'orientation de ses fibres, et qu'on dépose sur la face dorsale de la bande porteuse en appui sur un support, pour la pousser par aiguilletage à travers la bande porteuse jusqu'à la faire apparaître de manière visible sur la face antérieure de la bande porteuse en appui sur son support, caractérisé en ce qu'on prend une nappe de matière fibreuse en bande déjà aiguilletée pour la structurer par aiguilletage, afin d'obtenir une bande de velours constituant la bande porteuse, en opérant à plat sur un support formé par une bande de tapis-brosse qui présente une face d'appui homogène matérialisée par les pointes des poils de brosse, en ce qu'on dépose ensuite sur la bande de velours la matière fibreuse textile, suivant au moins une disposition permettant de réaliser un dessin, soit sous forme d'une nappe fibreuse couvrant toute la surface à traiter, soit sous forme de pièces séparées, et en ce qu'on effectue alors sur la bande ainsi préparée et en appui sur la bande de tapis-brosse une nouvelle passe d'aiguilletage, pour agir sur les fibres déposées sur la bande de velours en les poussant à travers cette bande, jusqu'à les faire apparaître de manière visible sur la face inférieure de la bande de velours, en boucles dont les sommets se trouvent sensiblement dans le plan de la face inférieure de la bande de velours.
