ABSTRACT:
A process and apparatus for the blow molding of oriented, hollow containers from tubular parisons in which a tubing of plastic material at a suitable orientation temperature for the material is passed by a puller assembly to a cutter assembly. The free end of the tubing is grasped by a parison transfer assembly, after which parisons are cut from the tubing by the cutter assembly and positioned by the transfer assembly for placement within blow molders. The first of two blow molders moves toward the tubing centerline from a molding position to receive a parison. The parison transfer assembly is extended vertically to place the parison within the molding cavity of the open blow molder. The upper end of the parison is grasped by a tube clamp, and as the parison transfer assembly retracts, the parison is stretched prior to molder closure. The closed blow molder returns to its molding position to complete the blow molding of a finished, oriented container. The parison transfer assembly accumulates another parison and positions it for placement within the second blow molder, which has moved from its blow molding position, and the cycles are repeated. Alternate embodiments are described for the parison transfer assembly and for parison stretching.
