ABSTRACT:
A press unit (20) for a manufactured wood press (60) is provided. The press unit includes a housing (80), a platen (90), and a drive assembly (76) 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.
