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.
