ABSTRACT:
A platen press has a pair of platens having respective confronting and parallel pressing surfaces and each having a pair of longitudinal edges. Respective spacer bars are fixed to the longitudinal edges of one of the platens and have respective spacer surfaces parallel to and between the platen surfaces. Respective adjustments bars are secured to the longitudinal edges of the other of the platens and each have an adjustment surface parallel to and confronting the respective spacer surface. Each of these adjustment bars is formed of an outer wedge having a pair of nonparallel faces one of which is the respective bar surface and of an inner wedge having an outer face flatly engaging the other face of the respective outer wedge. The inner and outer wedges can be relatively longitudinally displaced so as to displace the respective abutment face perpendicular to the respective platen surface. Thus when the platens are displaced together perpendicular to the surface the spacer surface flatly engages with the respective adjustment surface, holding the pressing surfaces apart at a distance equal to the thickness of the spacer bar plus a finish increment set on the adjustment bar.
