Definitions

  • the invention relates to a coffin made of molded pulp from cellulose fibers and a method for its production according to claims 1 and 4.
  • Such a coffin is known from DE-AS 26 44 487.
  • the open half of the coffin body is formed by pressing a mold made of a permeable material, for example a sieve-like material, into the sludge of a pulp in the reverse state of the coffin body, in such a way that the coffin part formed in the mold with its open part End is directed downwards.
  • a suction device is placed on the interior of the mold to pull the paper pulp against the mold surface.
  • the mold with the applied paper pulp is lifted out of the sludge of the paper pulp and a further suction device is applied to the interior of the mold in order to suck the water out of the paper pulp located on the mold and to compress it.
  • Compressed air is then applied to the interior of the mold in order to detach the absorbent body from the mold and subsequently dry the coffin under the influence of heat.
  • the strength of a coffin manufactured in this way is insufficient; in particular, the layer thickness of the paper pulp that is sucked in can fluctuate, so that weaknesses in strength cannot be avoided and the surface of the coffin can also have unevenness.
  • Another disadvantage is that unhomogeneous spots can arise in the coffin body during drainage.
  • the advantage is in particular that the pulp material emulsion is pumped into the molding press between the punch and the die under adjustable pressure and, at the same time, the pulp material suspension is dewatered via the perforated die designed as a core under reduced pressure.
  • the gap between the stamp and the die, which forms the filling mold, can be adjusted over a wide range and a controlled pressing process ensures the required strength of the coffin compact, the compact being homogeneous and the surfaces of which have a smooth press skin.
  • Another advantage is that all of the provided and necessary reinforcements, in particular in the coffin corners and in the areas of the carrying handles, are formed simultaneously during the pressing process in accordance with the stamp and die outer surfaces.
  • the activation of the waterproof binder admixed in the pulp material takes place during the heat treatment in the flow channel or already during the pressing process, if known heating devices are used in the punch and in the die. This increases the strength of the coffin significantly, which is particularly important for coffins of larger dimensions.
  • a punch 16 and a die 20 of a partially illustrated molding press 10 are shown, an upper pressure press preferably being used in which the upper press table 14 is vertically movable and the die 20 is designed to be stationary.
  • the stamp 16 which can be moved via a press piston 12, forms the outer compact surface with its outer stamp surface.
  • the die 20 is as an opening 22, for example formed of holes or similar slits and the like., permeable core, and represents an inverted coffin half, the downwardly open coffin half is closed with a sealing plate 24, and that between the perforated die 20 and the sealing plate 24, a core cavity 26 arises.
  • the outer die surface 20 'forms the inner compact surface.
  • a negative pressure for dewatering the pulp material suspension and / or via the openings 22 in a filling mold 30 provided between the punch 16 and the die 20 can an overpressure for demolding the compact 40 can be generated.
  • the gap a between the punch 16 and the die 20, which forms the filling mold 30, can be adjusted over a wide range depending on the coffin size for the required strengths.
  • the coffin half 40 shown in FIG. 2 is reinforced in the areas of the coffin corners 42 and the carrying handles 44 in the interior of the coffin.
  • the interlocking flanges 46 of the lower and upper part serve to screw the two coffin halves.
  • the open lower and upper parts 40 are each closed with an outwardly pointing edge 48, each of which fit a groove 50 running over the edge circumference, into which a wooden strip 52 is inserted, which engages in the grooves 50 of the lower and upper parts 40, making an immovable Adjust when joining the lower and upper parts 40 is ensured.
  • the pulp material is processed in a known manner in a material preparation (not shown), cellulose fibers, waste paper and / or wood chips together with water and a water-resistant binder known per se in a pulp mixer to form a pumpable pulp material suspension 54 be dissolved and mixed.
  • the plunger 12 By means of the plunger 12, the upper press table 24 is brought into the starting position together with the plunger 16, as a result of which an adjustable gap a is formed in the opened filling mold 30.
  • the pulp suspension is pumped into the filling mold 30, which is delimited by the outer punch 16 'and die surfaces 20'.
  • the perforated die 20 designed as a core is covered with a flat textile structure 32, preferably a felt cloth, in order to retain the cellulose fibers.
  • a negative pressure is applied in the core cavity 26 via the suction and compressed air line 36, so that the pulp suspension 54 pumped under pressure into the filling mold 30 of the molding press 10 is simultaneously drained by the suction effect through the openings 22 of the die 20 and thus the pulp is pre-compressed.
  • the unmolded compact 40 is removed from the opened mold 10 and fed to a flow channel for heat treatment, controlled temperature control not only drying but also activating the binder contained in the compact 40, thereby achieving the final strength of the compact 40
  • the punch 16 and the die 20 of the molding press 10 could also be designed to be heatable in a known manner, so that the activation of the water-resistant binder could take place in a controlled manner during the pressing process.
  • the coffin upper and inner surfaces are refined in a known manner, the lower and upper parts are screwed to the flanges 46, wooden strips 52 engaging in the grooves 50 of the lower and upper part edges 48 are inserted over the edge circumference and the Carrying handles attached.
  • the right side of the molding press 10 according to FIG. 1 is shown with the open filling mold 30 (gap a), in which the pulp suspension 54 has already been pumped in.
  • the left side of the molding press 10 shows the closed filling mold 30 '(gap a') with the finished compact 40 provided with the reinforcements.
