ABSTRACT:
An apparatus for manufacturing hollow resin products. The apparatus includes an extruder for extruding a tubular resin material and cutting the material into a parison with a specified length; a blow molding machine having an upper mold and a lower mold which form a cavity of a specified shape inside; and a parison delivering machine for receiving the parison from the extruder and feeding the parison into the cavity of the lower mold. The parison delivering machine includes a conveyer which has parison feeder for feeding a parison longitudinally from an inlet to an outlet, a driver for driving the feeder, and at least four shafts which serve as pivots of three-dimensional movement of the conveyor.
