Abstract
There is disclosed a novel apparatus for thermoforming a plastic article wherein the male mold assembly and the female mold assembly are disposed on support members which are maintained in fixed relationship to each other during thermoforming operation. The sheet of thermoforming material after initial heating is trapped by clamping devices associated with the assemblies with the male die and female die molds associated with the male and female mold assemblies, respectively, being operated by fluid cylinder assemblies motivated by pressurized fluid.
