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

Dosing hopper

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

Forming station with a gravimetric dosing belt scale for wood chips and fibers

The production of a mat of wood chips and/or fibers, hereafter called wood particles, by a spreading station and a weighing device, is controlled in a closed loop circuit for uniformity, directly during the spreading of the wood particles. Several spreading devices form a spreading station. Electrical signals emanating from a tared weighing device which is arranged downstream of a first spreading device as viewed in the direction of travel of a conveyor belt, are used to control the output of the first spreading device. If desired, the output of one or more spreading devices located downstream of a weighing device may also be controlled in a closed loop circuit, whereby the weight of the partially formed mat moving over the weighing device produces the electrical control signal which is compared to a predetermined reference signal for controlling the production of the finished mat having one or several layers.
