ABSTRACT:
Apparatus for simultaneously molding a plurality of bottles, and removing flash tails from the bottom of all of the bottles prior to removal from the mold includes a die having a plurality of cavities therein corresponding to the shape of the bottle to be molded. The die includes a plurality of concavities along an outer surface thereof, each next adjacent one of the cavities. A shaft is rotatably supported immediately adjacent this outer surface of the die, and extends substantially parallel with the row of cavities, the shaft further including a flat surface immediately adjacent each concavity along the outer surface. A blade is mounted on each flat surface, each blade having a greater dimension between the shaft and the second portion of the cutting edge with respect to the dimension between the shaft and an outer extremity of the cutting edge. Each cutting blade is movably fastened to the flat surface, such that the blade may be extended and retracted toward and away from the bottom of a molded bottle in the corresponding one of the cavities.
