A timing assembly () for a manufactured wood products press () is provided. The manufactured wood products press includes a first drive shaft () coupled to a first platen () and second drive shaft () coupled to a second platen (). The first and second platens are disposed within the manufactured wood products press in an opposed manner. The timing assembly includes a housing () and a plurality of timing gears () disposed within the housing. The plurality of timing gears are operatively connected to the first and second drive shafts for simultaneously driving the first and second drive shafts in an eccentric path.

Timing assembly for a manufactured wood products press

A press unit () for a manufactured wood press () is provided. The press unit includes a housing (), a platen (), and a drive assembly () disposed within the housing. The drive assembly is coupled to the platen to drive the platen in a non-linear motion. More specifically, the drive assembly includes a shaft having concentric and eccentric portions which are disposed on separate axes. Rotation of the eccentric portion about its respective axis causes movement of the platen in the non-linear motion.

Press unit for a manufactured wood product press

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.
