Abstract:
Apparatus for fabricating chip boards of fiber boards or cellulose material, comprising:a press having a receiving end; anda press form station arranged upstream of the press and having a storage bin for retaining a material in the form of chips or fibers, said storage bin including an outlet end for discharge of material, and a conveyor belt arrangement extending from the outlet end of the storage bin to the receiving end of the press for forcing the material in the direction towards the receiving end of the press, said conveyor belt arrangement including a first section forming a vertical, funnel-shaped compaction zone, and a second arcuate section arranged downstream of the first section for deflecting the material along a curved path from a vertical disposition into a horizontal disposition, wherein the material in the press form station is aligned in a vertical plane to form a three-ply mat, with a center layer formed by randomly positioned material aligned to a major degree perpendicular to a conveying direction and trapped between outer layers formed by material substantially aligned parallel to the conveying direction, said three-ply mat being compacted during passage through the conveyor belt arrangement and transferred into the press while maintaining a pressure application; andcontrol means for controlling a filling operation of the storage bin in response to a running speed of the conveyor belt arrangement.
