Abstract

BLOW MOLDING APPARATUS A blow molding machine having plural molds cyclically movable past an extruder for delivery to those molds of a tubular plastic parison includes a reciprocating blade which, upon interruption of the motion of the molds, is set in motion across the path of the parison emerging from the extruder to chop the parison into fragments and with a retractable trough for collecting the fragments for recycling or other disposition.
