ABSTRACT:
A press for the continuous production of thin chipboard and fibreboard includes a central rotatable drum and a feed roller; a nip being defined between the curved exterior surfaces of the drum and roller. An endless steel band passes around a major portion of the curved surfaces of both drum and roller and passes through the nip. Other rollers are provided for guiding, tensioning and applying pressure to the band. The feed roller has a large diameter, of at least 2 m, and is provided with drive means so as to be rotatable. These features, surprisingly, enable the board output to be increasing while, at the same time improving the physical characteristics of the board.
