A thermoforming apparatus for forming sheets of sheet plastic onto a substrate in which a retractable substrate heater is able to be positioned over a substrate loaded into the press and energized while a plastic sheet is being heated in an oven included in the thermoformer apparatus. The plastic sheets are cut from a strip pulled from a roll of sheet material, the roll supported for side to side movement and driven by a servomotor responsive to error signals generated by a strip edge sensor to compensate for wandering of a strip edge to thereby insure accurate location of plastic sheets cut from the unwound strip.
