ABSTRACT:
Apparatus for forming articles in a thermoplastic sheet, severing the articles in the sheet, and stacking the articles in a stacking receiver. The apparatus includes upper and lower molds moveable between closed positions in which the molds engage opposite sides of the sheet to differentially pressure form a part in the thermoplastic sheet. The molds in which the article is formed are moved toward each from the closed positions to article trim positions to sever the article from the sheet. The lower mold is then moved linearly away from the sheet in a vertical direction and then transversely moved in a second linear transverse path of travel to a remote discharge location. Apparatus is provided for reorienting the mold between its orientation in the first linear path of travel and its orientation in the second path of travel.
