  • Patent number: 7278551
    Abstract: A dosing hopper for producing wood material panels has a feed device (2) that distributes the supplied material flow of glued wood particles continuously over the width of the hopper (1). The dosing hopper supplies elongated flat wood strands for producing oriented structural chip boards or panels (OSB, LSL). The feed device (2) includes a weighing device (23), with which the wood strands are distributable over the entire hopper width in a weight-dosed and oriented manner.

  • Patent number: 6767421
    Abstract: A method of making panel-shaped products by hot-pressing a multi-layered formed body of chips of lignocellulose-containing annual plants impregnated with an isocyanate binder, is to avoid the problem of the adhesion of the isocyanate binder. For this purpose, the cover layer material is divided into a cover layer material fine fraction (5a) and a cover layer material coarse fraction (5b), whereby the cover layer material fine fraction (5a) is pre-mixed with adhesion promoters and/or wetting agents and/or acids and/or bases, and next glued with amino and/or phenolic plastics, and the cover layer material coarse fraction (5b) is glued with isocyanate or mixtures of isocyanate and amino and/or phenolic plastics. Next, a five-layered formed body is spread, whereby the outermost cover layers of the formed body consist of the cover layer material fine fraction glued with amino and/or phenolic plastics.

  • Patent number: 6695605
    Abstract: Forming station with a metering or dosing hopper, out of which flowable materials, especially chip and/or fiber-form materials are delivered to a spreading apparatus, by which a material fleece is spreadable onto a forming belt, characterized in that a compartmentalized chute (2, 51) is provided vertically and longitudinally in the transport flow between the dosing hopper (1) and the forming belt (4, 53), wherein the compartmentalized chute consists of plural guide plates (9, 39, 40, 41, 54, 56, 57) which are arranged next to one another in the transport direction (36) and which divide the transport flow into plural partial flows (38, 55, 56) in the transport direction (36, 62, 76).

  • Patent number: 6679694
    Abstract: A spreading station for spreading chip or fiber panels, includes a dosing belt scale (2) to provided between a dosing hopper (1) and a spreading head (3). The dosing belt scale (2) is connected to a regulating unit (4, 22) with which the conveying rate (kg/s) of the chip or fiber material on the dosing belt scale (2) is gravimetrically regulatable based on a prescribed fleece weight or a prescribed nominal conveying rate that is to be achieved.

  • Patent number: 6652695
    Abstract: In a method of producing panel-shaped products by hot pressing a formed multi-layered body of lignocellulose-containing chips impregnated with binder, different binders are used in the middle layer and in the cover layers arranged on both sides of the middle layer, the cover layers consist of chips of wood or other raw materials based on wood impregnated with a binder including amino and/or phenolic plastics, and the middle layer consists of a mixture of chips of lignocellulose-containing annual plants chips of wood or other raw materials based on wood impregnated with a binder including an isocyanate.

  • Patent number: 6612446
    Abstract: A spreading roll for spreading out a chip fleece for producing wood chip material or similar panels, includes two disk-shaped end pieces (3, 7), plural thin spokes (6), rods, pipes or cords arranged extending between the end pieces, and pipe-shaped loose sheaths (9, 10, 11, 12, 13) arranged on the spokes or the like for preventing the adhesion of fibrous materials or contaminants on the spokes or the like.
