ABSTRACT:
A device for cutting off a sprue of a parison with a bottom is capable of cutting off the sprue in a heating furnace. Cutter plates for cutting the sprue and an outlet for discharging the cut sprue are disposed at the bottom of the heating furnace. Cutting off the sprue may thus be performed without changing the usual molding cycle of the hot parison molding method. The device may alternatively be applied to the cold parison molding method.
