Definitions

  • the respective outer thread or fiber layer is in many respects for the properties or determining the use of the semi-finished product.
  • the bending resistance transverse to their longitudinal axis is to a large extent decisive for its possible use. This is particularly true for the covering of aircraft and hulls of ships.
  • the semi-finished products are light and should be inexpensive to manufacture.
  • optically detectable surface structure of such a structure is the optically detectable surface structure of such a structure. It is regularly desirable for the surface structure to match the structure of the future product or not to interfere with it.
  • Threads of this type are regularly pre-fixed on warp knitting machines using the so-called sewing process.
  • warp knitting machines of the known type no so-called standing weft threads can be incorporated on the right side of the knitted fabric, which extend over longer sections exclusively in the working direction of the warp knitting machine.
  • thread or fiber fabrics can be compacted and pre-fixed which have thread or fiber layers placed diagonally or transversely on their underside, the right side of the knitted fabric.
  • Such thread or fiber systems can be stretched between transport chains and easily guided to the stitch formation point of a warp knitting machine in the knock-off plane by knock-off boards.
  • a middle layer of wefts are u. a. one or more layers of thread sheets attached above and below, which are inclined at different angles to the working direction.
  • the outer layer was designed with a very small one Angle - usually 30 ° - to the working direction of the thread.
  • the laying arrangement is already over 10 meters long with three laying devices.
  • Fibers that are stretched between the transport chains are stretched between the transport chains.
  • fiber slits are left on the laid scrim! applied, which are connected to the scrim during the knitting process.
  • a second knitting process is necessary to cover the right side of the knitted fabric with the same fiber chips.
  • an endless conveyor belt was positioned below the laying arrangement and between the transport chains, the upper run of which was supported from below.
  • the dimensions of the conveyor belt made it necessary to reliably guide the scrim from the moving conveyor belt over a free distance into the knock-off plane of the warp knitting machine.
  • the diagonal, lower thread layer was also used for this.
  • endless guide wires were used together with the conveyor belt, which could be passed through the lanes of the needles in the knock-down plane without them being involved. These endless guide wires could then be returned to the entrance of the laying arrangement and led there onto the conveyor belt. Such guide wires and their guidance are extremely expensive and only solve the latter problem.
  • the scrims used to reinforce large, flat, web-shaped semifinished products have a structure as shown and described in DE 33 04 345 C2 or DE 33 43 048 A1.
  • the required bending stiffness in one direction is mainly guaranteed by a single standing thread system or a maximum of two central standing thread systems. All other diagonal thread systems only contribute as more or less elastic members with a limited part to increase the bending strength in the direction mentioned. It is clearly evident to the person skilled in the art that thread layers designed in this way have only limited bending stability transversely to the longitudinal direction of the semi-finished product. To ensure a given bending stability, additional reinforcing elements are usually inserted, which increases the mass and increases the costs.
  • the present object is achieved in a surprisingly simple manner by claim 1.
  • a standing weft layer which is directly adjacent to the needle stitches of the stitch composite, and with an alignment of the needle stitches crossing the standing wefts on the right side of the stitch composite, the standing weft layer is held reliably and stably on the entire pre-fixed laid scrim.
  • the pre-consolidated scrim can be temporarily stored without wrinkles by winding. If standing weft thread systems are arranged on both outer sides of the laid scrim, a high bending strength is achieved in the final state.
  • the designer of a semi-finished product is given the opportunity to choose any layers between the standing thread systems that meet the requirements insert, which on the one hand can guarantee a certain distance between standing thread layers and on the other hand cause additional reinforcement in secondary directions.
  • the reinforcement in secondary directions can often ensure less compact fiber or fleece elements. These fiber or nonwoven elements usually have a lower mass and can be manufactured and supplied with less effort.
  • the arrangement of the visible fiber or thread layers symmetrical to the longitudinal direction in many cases makes additional measures for the design of the surface superfluous.
  • the standing weft threads on the right side of the mesh can also be guaranteed without a needle stitch offset or without an offset of the knock-off elements. In this case, however, it is necessary to guide the fibers of limited fiber length without interference on the underside of the standing weft threads into the knock-down plane.
  • the advantage of this arrangement is that the fiber chips so applied cover and dissolve the surface structure created by threads of a certain orientation.
  • the system for producing a pre-consolidated thread or fiber scrim according to claim 11 enables the method of operation described in relation to claim 1, claim 2 and claim 6 with the simplest usability.
  • the claim 14 defines the essential features of the multi-layer, prefixed thread or fiber fabric that can be produced with the method according to claim 1, with wrinkle-free intermediate storage capacity and the prerequisite for ensuring a high bending stiffness.
  • the claim 15 describes a thread or fiber fabric that is optimally designed with regard to the bending stiffness.
  • the thread or fiber scrim according to claim 16 is realizable with relatively easy to control technical means and with few steps offers the prerequisites for the visible surfaces to have an irregular structure on both sides.

  • the stitch formation point of a warp knitting machine shown in cross section in FIG. 1 is constructed on the principle of sewing knitting.
  • the vertically arranged knitting needles 1, which are designed here as pusher needles with pusher 2 have a tip on their head which can penetrate the scrim from bottom to top at any point.
  • the knitting needle bar 10 and thus also the slide bar 20 are in the tee phase, i.e. that is, when its needle tip is below the scrim G and below the knock-off elements 3, laterally displaceable.

Abstract

L'invention concerne un procédé et une unité de production d'une structure de fils ou de fibres (GF) multicouche, préfixée à l'aide d'une combinaison de mailles et utilisée comme demi-produit en bande pour armer des parties en matière plastique ou en résines. Selon cette invention, cette structure de fils (GF) comprend des couches de fils de trame fixes (K) et des couches de nappes de fils ou de fibres (S, D, D'), étirées entre des chaînes de transport avec des orientations différentes. L'objectif de cette invention est de réduire les coûts et diminuer la masse superficielle nécessaire pour garantir une rigidité flexionnelle requise déterminée. A cet effet, ledit procédé est mis en oeuvre, de sorte que la couche de trame fixe (KR), constituée de nappes de fibres ou de fils et orientée parallèlement au sens de travail, est agencée de façon directement adjacente aux mailles d'aiguille (WN) de ladite combinaison de mailles et de sorte que des mailles d'aiguille (WNv) de cette combinaison croisent les fils ou fibres de la couche de trame fixe dans la phase d'abattage, avant que les aiguilles à tricoter (1) ne pénètrent à nouveau dans la structure de fils (G) afin de former une rangée de mailles suivante.
