Definitions

  • the invention relates to a process for the production of thin-walled profile bodies from dry or only slightly moist glued fibers by filling and compacting in a press.
  • the fibers can be, for example, a fibrous material which is produced from particles containing cellulose or lignocellulose in such a way that they are digested with steam, hot water or weak alkalis and defibrated in defibrators and then dried.
  • other fibers such as glass fibers, can also be processed with the method according to the invention.
  • thermosetting synthetic resins for use in vehicle construction, in the furniture industry or in the electrical engineering industry.
  • the known methods are used, for example, in such a way that only slightly compressed, flat mats are produced from the fibers, which are then carried out in a second operation be pressed in a press with simultaneous supply of heat to the finished profile body.
  • fiberboard is already fully cured. These are softened again by applying moisture and heat and then pressed into the finished profile body in a press.
  • the object on which the invention is based is therefore to specify a method and a device which make it possible to produce profile bodies directly from glued fibers.
  • the belemite fibers are blown into a closed volume, the size of which corresponds to the bulk volume of the profile body, in which two opposing boundary surfaces are formed by the surfaces of two pressing tools shaped according to the shape of the profile body and in the other boundary surfaces are arranged at least one injection opening for the glued fibers and at least one, covered with a sieve suction opening for the transport medium, and that the glued fibers are then moved by moving the one press tool is compressed to the other pressing tool.
  • the fibers can be blown into the volume in a uniform or deliberately non-uniform distribution and pressed to the profiled body immediately after the volume has been filled.
  • the profile bodies to be produced have a strongly structured shape or if they are to have different densities at different locations, it has proven to be expedient to glue the glued fibers in the press in which they were blown in only to a part of the desired final density compress it into a pre-compact, take it out of this press, insert it into a second press and finish it there with the addition of heat to final density.
  • FIGS. 1 and 2 The exemplary embodiment of a device for carrying out the method according to the invention is illustrated in FIGS. 1 and 2.
  • the press shown has a fixed pressing tool lower part 1 and a pressing tool upper part 2, which can be moved in the direction of arrow 3 towards the pressing tool lower part 1 and away from it.
  • Fig. 1 the press is shown in the open state; then the volume 4 to be filled with the glued fibers is present between the pressing tool lower part 1 and the pressing tool upper part 2.
  • This volume 4 is delimited on the left side by the injection opening 5, through which the glued fibers transported in a compressed air line are blown into the volume.
  • the counterpart to the blowing opening namely the blowing opening 7 closed with a sieve 6, can be seen, through which the air which is no longer required can be discharged or possibly even extracted.
  • the press can be provided with several blow-out openings which are connected to a common exhaust line 8.
  • the blow-out openings can be used in different ways to fill the fibers either evenly or specifically non-uniformly (for the purpose of producing different densities in the profile body) in the volume. For this purpose, they can have different cross sections, for example.
  • suction openings with devices, such as flaps, which allow the cross-section to be changed continuously.
  • devices such as flaps
  • the pressing tool lower part 2 is provided with a plurality of channels 9 of small cross-section, which are connected to the atmosphere, but can also be acted upon by compressed air. If the channels 9 are in connection with the atmosphere, then they prevent a vacuum from forming below the pressed profile body, which prevents it from being released from the lower part of the pressing tool. If the channels 9 are pressurized with compressed air after the pressing process, then the pressed profile body is raised and can be easily removed from the press.
