ABSTRACT:
A thermoforming press in which the shut height of upper and lower platens is adjustable by a keyed connection between a press frame top assembly and each of four posts of the frame established by pieces which are movable and which also act as cams to raise or lower the frame top assembly, moving the upper platen therewith to vary the shut height. The movable pieces are moved in unison by a drive motor to insure uniform movement of the frame top assembly. The platens are driven by rotary crank plates, which are in turn driven by rotary output shafts of right angle drives. Pairs of rollers engage the perimeter of each crank plate on one side to resist bending loads on each shaft.
