Abstract: A flexible screw of the invention comprises a flexible rod and a cord helically set on the rod, and can be installed along straight and curved paths of transport. It ensures smooth transport of containers and provides container transport apparatus with a simplified construction at a reduced cost. Moreover, the abrasion of pipe during transport of powder and granular material can be reduced. The container transport apparatus of the present invention is equipped with the screw mentioned above and a guide, or two screws, the members of each pair being positioned in parallel at a given distance, and transfers containers held by the screw and the guide, or the two screws by rotating the screw(s). The container transport apparatus of the present invention enables smooth transport of containers even through a curved path, reduces maintenance cost of the screw(s) during operation, and inhibits abrasion of the rail to a considerable degree.

Abstract: An apparatus for manufacturing a hollow synthetic resin product, including a movable parison guide and a movable lower molding portion which align an extruding head, the parison guide and an end of the lower molding portion in a perpendicular plane. The lower molding portion is moved in a direction perpendicular to the perpendicular plane while a parison is extruded from the extruding head, while the parison guide is moved in a direction crossing the moving direction of the lower molding portion in accordance with a shape of a groove of the lower molding portion to accommodate a first portion of the parison in the groove. A cutter cuts the parison in a predetermined length when the predetermined length thereof is extruded, while a parison pinch holds a portion of the parison to be cut immediately before the parison is cut.

Abstract: The method includes moving a parison guide and a lower molding portion to substantially vertically align an extruding head, the parison guide and an end of the lower molding portion. Then, the lower molding portion is moved substantially horizontally while extruding a parison from the extruding head, while the parison guide is moved laterally in a direction crossing the moving direction of the lower molding portion in accordance with a shape of a groove of the lower molding portion to accommodate a first portion of the parison in the groove. Subsequently, the parison is cut into a predetermined length when the predetermined length thereof is extruded, while a portion of the parison to be cut is held by a parison pinch.
