Abstract: A method for producing a wood wool construction element. This method comprises the steps of dispersing at least a part of a mixture of wood wool and a hydraulic binder in a mold so as to obtain a layer of the mixture with a height that is less than the height of side walls of said mold. Said mixture is at least partially hardened after which a subsequent layer of mixture is provided. The thickness of a construction element may well exceed 30 cm, for example 40 cm, 50 cm or even 60 cm. Also, an element obtained with such method is described, as well as a production facility.

Abstract: A mineral bonded Wood Strand Cement (usually Portland cement or Magnesite or Gypsum) Board which is produced from a mixture of wood strands or a similar fibre material, water, a suitable binder like cement, and possibly additives, which mixture is cured under pressure to form a board with a practically entirely closed surface. For the boards according to the invention, wood strands are being used that are broader and thinner than used until presently in acoustic Wood Wool Cement Boards. Moreover, the invention relates to a method of orienting wood strands and a production process for the production of such Wood Strand Cement Boards.

Abstract: The invention relates to a knife assembly for slicing woodwool, comprising a knife with a chip surface (1), a clearance surface (2) and a cutting edge (3), defined by the intersection between both surfaces. The knife assembly is characterized by guiding ribs (4) extending perpendicularly to the cutting edge (3) and joining the chip surface (1) with an end (5) that substantially coincides with the cutting edge (3) and with the guiding surface joining said end and rising there towards. The guiding ribs (4) can be formed integrally with the knife.

Abstract: The invention relates to an apparatus for producing sideways curved wood wool fibers. The apparatus comprises a flat rotatable disc (2), in the surface of which is provided at least one knife assembly (7) comprising a thickness knife (8) which projects slightly above the surface of the disc (2) and which has a cutting edge extending substantially radially and further comprising width knives (9) positioned as seen in the direction of rotation of said disc (2), ahead of said thickness knife (8) and having a cutting edge extending substantially tangentially. The width knives (9) are positioned in the immediate vicinity of the thickness knife (8), whereas their cutting edge may engage the thickness knife (8). Further the apparatus is provided with at least one feeding device (5) for feeding the disc (2) with wood blocks (6) to be cut up into fibers. Further a run-up guide may be positioned ahead of the width knives.

Abstract: A horizontal supply conveyor carrying a board with a number of loaves of cheese thereon is mounted for vertical adjustment in front of the open ends of a multiplicity of horizontal guideways disposed in superimposed and in juxtaposed relationship. By selective adjustment and selective operation of the conveyor the board is moved into registry with a selected one of said guideways whereupon a pushing device pushes the board from the conveyor and into the guideway in which similar loaded boards are stored the last one of which is thus discharged from the rear of the selected guideway onto another conveyor to be moved back to the first conveyor by transporting means which include a device for turning over the loaf. The walls separating adjacent units constitute ducts for the supply and discharge of air to the guideways accommodating the loaves of cheese.
