Abstract
A press assembly is shown having a plurality of aligned press modules having a lower platen and an oppositely-disposed upper platen, the press modules defining a channel through the press assembly. A resinous wood fiber mat is fed into the channel. The upper and lower platens are driven along synchronized circular paths of travel such that the mat is compressed between the platens and is propelled by the platens through the channel. The platens are connected to eccentric shaft drive assemblies that move the platens along the desired circular path. The action of the eccentric shafts of each module are interconnected and coordinated by gear box units, and the gear box units are interconnected by intermediate gear boxes to synchronize the press assembly. A plurality of motors drives the eccentric shafts, and the supplied power may be distributed by the gear boxes.
