Definitions

  • the invention relates to a spinning method and a spinning device for producing a yarn with ring yarn-like character, according to the preamble of the independent claims, in which at least one fiber structure is dissolved from a dissolving agent to individual fibers and the individual fibers are taken over by a moving collecting and conveying surface and in a predetermined direction conveyed and ultimately turned into a yarn in a spinning unit.
  • a fiber template also called a fiber structure
  • the template is refined and parallelized in a drafting system (Fig. A), after which the fibers of the fiber structure are twisted together in a spinning triangle and spun in a spinning unit (A.2).
  • the template is broken up into “individual fibers” by a disintegration roller (FIG. B) and fed to a redoubling or fiber collection system, for example a rotor.
  • a disintegration roller for example a rotor.
  • the fiber stream fed to the end of the yarn has also been refined, that is to say the process with an opening roller also produces a delay.
  • the fibers leaving a drafting system have a relatively high degree of orientation (A. 1), which favors the optimal utilization of the fiber substance in the yarn. This variant is therefore used when high quality is required.
  • the drafting process is relatively expensive.
  • the maximum delay in the drafting system of a final spinning process is limited to approx. 200 to 300.
  • the incoming fibers should have a minimum orientation if possible (known checkmark theory).
  • a complex preparation is therefore required before entering the drafting system (several drafting passages, if necessary combing out short fibers).
  • the drafting device is relatively complex and requires a lot of maintenance - load system, roller covers, (the have to be sanded), straps (which have to be replaced regularly), exact adaptation to the material to be processed. In addition, it is not possible to remove dirt in the drafting system because the original is not dissolved on individual fibers.
  • the method (Fig. B) with an opening roller (B. 1) is relatively robust and easy to maintain. There are only a few individual parts and they are relatively easy to set. The process can produce a relatively high delay (approx. 500) and can therefore work with a stretch belt from the first passage, if necessary even with a card sliver as a template. Because the original is broken down to individual fibers, it is possible to remove dirt (B. 2) in direct connection with the dissolution.
  • the disadvantage of the opening roller is, however, that the fiber orientation (B. 3) of the template after the opening, i.e. H. is lost in funding and cannot be restored until it is screwed in. So far, this method has only been suitable for the production of yarns for limited areas of application.
  • Fig. C It would be desirable to develop a method (Fig. C) which, on the one hand, the robustness and ease of maintenance of the opening roller (C. 1) with the fiber orientation (C. 2) of the product from the drafting system and at least the dirt removal option (C. 3 and / or C.4) to produce a high quality yarn (C. 6).
  • a device for producing a yarn with ring yarn-like character which is provided with a disintegrating roller for disintegrating at least one fiber structure to individual fibers, and with a collecting and conveying roller for transferring and receiving and conveying the individual fibers against one another Element with a fiber conveying channel, by means of which the fibers are conveyed against a rotating or stationary hollow spindle, through which the yarn mentioned is drawn, swirl nozzles being provided at the output end of the fiber conveying channel, which on the one hand a suction air flow through the fiber conveying channel and on the other hand a rotating one at the end of the fiber conveying channel Generate airflow, by means of which rear ends of individual fibers are spread and around the Mouth edge of the hollow spindle and thus to be turned into a yarn around the fibers located therein.
  • the opening roller is provided with teeth which deliver the fibers in the same conveying direction to a first suction roller and this in the same conveying direction to a second suction roller, with the fibers from one of the second suction rollers Clamp line are released into the fiber feed channel.
  • This clamping line is created by means of a full roller pressed against the second suction roller. The yarn is drawn off from a pair of take-off rollers after the spinning device.
  • the fibers are taken over in the same direction of conveyance by the first and second suction rolls, this being done here in order to obtain a warp in the fiber structure analogous to a drafting system.
  • the disadvantage is that the opening roller has a lower peripheral speed than the first suction roller, which has to take over the fibers from the opening roller, which results in a fiber transfer which is not precisely defined and which could produce non-uniformities in the following fiber structure.
  • Another disadvantage is that any dirt, which is mentioned per se in this application, is only deflected by means of a separating knife provided after the fiber sliver dissolving. Such a dirt separating element is known from practice. On the other hand, dirt, which does not appear essentially as dust but essentially as trash parts, i.e.
  • a further step according to the invention for stretching the fibers and for separating the trash parts from the fiber structure consists in that at least a sufficient speed difference at the transfer points, i.e. a speed gradient from the opening step to the collecting step and / or a speed increase from the collecting step to the conveying step in the fiber channel, the conveying direction of the fiber collecting surface advantageously being opposite to the conveying direction of the opening roller, so that the fiber taken over by the collecting conveying surface after the front end of the collecting conveying surface was detected, the rear part of the fiber is conveyed further at the peripheral speed of the opening roller, so that the fiber creates a kind of rollover in order to lie in the opposite direction to the conveying direction of the opening roller on the collecting conveyor surface, the fibers being stretched out and trash parts being thrown away.
  • the front ends are caught by the air flow generated by the fiber conveying channel, while the following part of the fiber is still on the Fiber conveying surface lies and thereby the fiber undergoes a sharp deflection at the transition into the fiber conveying channel, which further helps to stretch the fiber by means of the tensile force of the air flow and to separate out any remaining trash parts tangential to the conveying direction of the collecting conveying surface.

Abstract

Au cours d'un procédé de filage à tuyères, un cylindre couvert (5) sépare des fibres en fibres individuelles, et un cylindre d'aspiration (9) transporte ces fibres contre un canal de transport de fibres (15) à partir duquel les fibres sont guidées contre la sortie d'un canal de fil d'un pivot creux (13). Les extrémités avant des fibres sont reçues dans le canal de fil (14), alors que les extrémités arrières sont prises par un courant d'air rotatif (R) et tournées autour de la zone de sortie du pivot ou du canal de fil de manière à produire un fil présentant au moins une surface de type fil de continu à anneaux. L'invention est caractérisée en ce que les fibres sont séparées lors de la transition du cylindre couvert (5) vers le cylindre d'aspiration par modification brusque du sens de marche sur les tôles de guidage (8, 17) de déchets ne pouvant pas suivre cette modification du sens de marche en raison de l'inertie des masses. De cette manière, lesdits déchets provoquant des interruptions de filage dans la zone située entre la sortie du canal de transport de fibres (15) et l'entrée du canal de fil (14) sont séparés à temps avant entrée dans le canal de transport de fibres.
