Abstract: A large lightweight molded coffin comprises a large pulp molded outer shell lined with a reinforcing spacer material such as single faced Re-board®, a honeycomb structure or a molded spacer material conforming to and adhering to said shell and an inner shell made of molded pulp or a paper based material. A method for manufacturing such a lightweight coffin involves pressing slurried pulp between a first male mold half covered with elastomeric material and a second female mold half, to form the molded pulp shell, and gluing the reinforcing spacer material to the interior of said outer molded pulp shell and the inner shell.

Abstract: Press for making large molded pulp objects, which has a raisable and lowerable male mold half, perforated for suction dewatering after dipping into a pulp slurry. The molding surface of said male mold half is coated with an elastomer to preserve even surface contact with the molded pulp object during compression and during thermal expansion or contraction of said mold halves. Advantageous embodiments include vacuum distribution troughs beneath the elastomer layer in the male mold half, multiple wire mesh layers on top of the perforated elastomer layer, and slight lateral adjustability of the otherwise stationary female mold half.

Abstract: A large lightweight 3-D shaped molded pulp material, for example a container, comprising a large pulp molded outer shell lined with a reinforcing core spacer material, conforming to and adhering to said shell, and an inner shell made of molded pulp or a flexible paper based material. A method for manufacturing such a lightweight material involves pressing slurried pulp between a first male mold half covered with elastomeric material and a second female mold half, to form the molded pulp outer shell, and gluing the reinforcing core spacer material to the interior of said molded pulp shell and gluing the inner shell to said spacer material.

Abstract: The present invention relates to a device and a method for increasing the yield, as well as for enabling an increase in productivity and an increased amount of production, and at the same time to improve purification of process water and waste water, respectively by decreasing the waste water flow and the amount of pollutants in the waste water.
