Abstract:
1. Apparatus for blow molding containers from a thermoplastic material, said apparatus comprising: extruder means for continuously extruding a spaced apart plurality of tubes of the thermoplastic material downwardly along a spaced apart plurality of vertical axes; a first mold, said first mold having a first set of mold halves that open and close relative to each other to define, when closed, a plurality of first mold cavities; a second mold, said second mold having a second set of mold halves that open and close relative to each other to define, when closed, a plurality of second mold cavities; means for moving said first mold along a first closed path to present said first mold at a first position to engage, when open, a plurality of first finite lengths of the thermoplastic tube for blowing of the plurality of first finite lengths of the thermoplastic tubes into a plurality of containers as the first mold moves from the first position to a second position of the first closed path; and means for moving said second mold along a second closed path to present said second mold at the first position to engage, while open, a plurality of second finite lengths, of the thermoplastic tube for blowing the plurality of second finite lengths, of the thermoplastic tubes into a plurality of containers as the second mold moves along the second closed path to a second position of the second closed path;
