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).

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.

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.

Abstract: A method and apparatus for preparing a mat of predetermined thickness from spreadable material for ligneous-material wall boards is disclosed.

Abstract: Process and apparatus for spreading a chip web from a supply over a width corresponding to the web width on a substrate moving below the supply. Such spreading is accomplished according to a web height distribution specified in the web transversely to the direction of web travel. The apparatus includes a rake-like distribution device and a distribution chute arranged between the supply and the web laydown for the purpose of eliminating defects caused by delivery elements in the transverse distribution of the chip web. An arrangement of several rakes inclined toward one another functions to control the transverse chip distribution.

Abstract: A process for the production of a fiber web on a movable, gas-permeable surface of a continuous laydown belt which is under vacuum and which forms a distribution chamber. After the fibers are mechanically opened, the fiber flow is conducted into the distribution chamber by means of an air current and additional air currents are delivered to the distribution chamber. An additional air current is introduced into the distribution chamber for the purpose of preventing a lumping together of fibers prior to the laydown in the web while the carrying air current is delivered to the distribution chamber in a nozzle-shaped chute. After the fibers have been laid down in a web, the web is precompressed by means of a controllable vacuum.
