ABSTRACT:
A parison transporting device includes a conveyor system moveable either in longitudinal or transverse fashion relative to the direction of parison discharge in the tube receiving position below the tube forming head to receive, on the conveyor system, either a straight tubular piece or a tubular piece curved in accordance with the mold cavity of the blow mold. The conveyor system is then moved to the blow mold and into a position where an end section of the conveyor belt is positioned vertically above an end section of the mold cavity with the tubular piece located thereon. A rotating conveyor belt carried by the conveyor system is moved above the mold cavity either in both horizontal directions (X-direction and Y-direction) to arrange the straight tubular piece into the curved mold cavity, or, in the alternative, linearly above the mold cavity to drop the tubular piece, already positioned in curved fashion on the conveyor belt, into the correspondingly formed mold cavity.
