ABSTRACT:
One apparatus for forming a workpiece made of thermoformable plastic material includes: (a) a base member; (b) a positioning wheel or a positioning frame supported by the base member; (c) a suspension tray for supporting a raw workpiece, the suspension tray being supported by the positioning wheel or the positioning frame; (d) a pair of relatively hot dies; (e) a first support arm positioning the hot dies, the first support arm being supported by the base member; (f) a first cylinder mounted on the base member for moving the first support arm whereby the hot dies may be positioned above and below the raw workpiece; (g) a pair of relatively cold dies; (h) a second support arm positioning the cold dies, the second support arm being supported by the base member; (i) a second cylinder mounted on the base for moving the second support arm whereby the set of cold dies may by positioned above and below the workpiece; (j) a press platen; and, (k) a cylinder for moving the press platen whereby the hot dies may be closed upon the workpiece when the pair of hot dies is in position above and below the workpiece and the cold dies may be closed upon the workpiece when the pair of cold dies is in position above and below the workpiece.
