ABSTRACT:
A machine for automatically forging and thermoforming of hollow thermoplastic biaxially oriented articles has a carrier assembly to carry, lock and unlock forging dies, indexing means to move the carrier assembly and dies past a series of work stations, and an article unloading means. Three work stations are in the automatic machine: forging where the die parts are locked together and the workpiece is forged into engagement with the die; thermoforming to which the die with the workpiece (now called a preform) gripped therein is moved into register with thermoforming mold means; and article ejecting means which include mechanical means for unlocking the die and removing the hollow article therefrom. The carrier assembly is so supported that the strains of forging and thermoforming are taken up by frame tie rods rather than the die mounting means.
