Definitions

  • the present invention relates to a device for producing a flat component reinforced with rovings according to the preamble of claim 1.
  • Such a device and a method for this is known from DE Patent 37 17 321.
  • An annular nozzle is provided there, with which a hose reinforced with rovings is produced.
  • the hose is placed on a shelf in a still plastically deformable state after a layer oyster and then pressed into a flat component. It is also envisaged to slit the length of the tube before laying it down and to lay the flat web obtained by opening it up according to a pattern.
  • the object of the present invention is to provide a device with which a flat web reinforced with rovings can be produced inexpensively, which can optionally be deposited according to a pattern and pressed into a flat component.
  • FIG. 2 shows the device according to FIG. 1 in a partially sectioned top view
  • Fig. 3 shows the extruder head when placing the extruded flat sheet on a tray
  • 1 and 2 denotes a part of an extrusion device.
  • This has an extruder 2 with an extruder screw 3, the extruder 2 being tightly connected to a flange 5 of an extruder head 6 via a flange 4.
  • the extruder head 6 has a sprue opening 7, to which the spray nozzle 8 of the extruder 2 can be pressed.
  • the latter has an extruder nozzle designed as a slot die 9 with a die slot 10 which has a height 10.1 and a length 10.2.
  • a feed device 11 for rovings 12 is provided on the extruder head 6 between the sprue opening 7 and the mouth of the slot die 9. This feed device 11 extends over the entire length or almost the entire length 10.2 of the die slot 10 or the extruder head 6.
  • the feed device 11 has, distributed over the length 10.2, in particular evenly distributed, feed openings 13. These are located above corresponding inlet openings 14 on the adjacent flat side 6.1 of the extruder head 6.
  • thermoplastic polymer material 15 made of at least one thermoplastic, thermoset or elastomer is used as the extrusion material.
  • Polyamides, polyethylene, polypropylene and polyester are particularly suitable.
  • the material 15 melted in the extruder 2 is injected into the extruder head 6 and extruded from its die slot 10 as a flat web 16.
  • the rovings 12 fed in via the feed device 11 are drawn in and extruded from the nozzle slot 10 and coated with the material 15.

Abstract

L'invention concerne un dispositif de production d'un composant plat renforcé en stratifil (12) et réalisé dans au moins un matériau polymère (15) thermiquement déformable. Le stratifil (12) à ajouter à la masse fondue du matériau polymère est conçu de telle façon qu'une bande plate renforcée en stratifil (12) puisse être produite économiquement, déposée selon un motif et comprimée pour obtenir un composant plat. Pour ce faire, la buse extrudeuse est une filière plate (9) et un dispositif d'alimentation (11) permet d'assurer l'alimentation en stratifil (12) en amont de l'embouchure du nez de la buse de la filière (10).
