A rectangular article boxing method of the present invention includes: a step of erecting upright and aligning a bundle of rectangular articles, gripping, lifting, transferring, and lowering the bundle and inserting the bundle between a first guide and a second guide disposed at a predetermined interval in a carton; a step of displacing the first guide to above the upright bundle; a step of moving the inserted bundle to a position in contact with the existing bundle and holding the bundles with the second guide; a step of holding the upright bundles with the first guide in place of the second guide; and a step of displacing the second guide to a position at the predetermined interval from the first guide to receive the bundle to be conveyed next.

Method and apparatus for boxing rectangular articles

When compression molding is performed continuously, lumps of molten synthetic resin (drops), which are supplied by extrusion, are continuously, accurately, and rapidly inserted into plurality of compression molding dies which are rotatingly movable. A method and device for continuously supplying drops into female moldings which are rotatingly movable for manufacturing moldings, wherein synthetic resin in molten condition extruded from an extrusion opening is cut by a cutter attached to a holding mechanism to form the molten resin into drops in a determined quantity, the drops are held and conveyed by the holding mechanism, and the drops are forcibly inserted and supplied into the concaves of the female moldings. At that time the holding mechanism on the rotary-and movable type drop supply is made to approach the rotating molding die and the rotation path of the holding mechanism is made to overlap with that of the molding die within a determined area to make the movement of the holding mechanisms follow that of the molding die.

To provide a preform, a bottle and a preform molding apparatus capable of preventing lowering in the mechanical strength of a preform, reducing the amount of a resin material, as well as improving productivity. A preform moldused in the preform molding apparatus has a mouth neck part mold, a body part moldand a core mold, and the body part moldhas, on the outer edge of the upper surface of a cylindrical protrusion part, an annular protrusionwhich controls the moving direction of a solidified filmand a solidified filmwhich have been peeled.

Inner surface strain of a container is reduced by suppressing a temperature drop of blow air, and heat resistance of the container is increased by enhancing the degree of crystallization. A blow air supply unit for a blow molding machine for molding a hollow bottle containerby supplying heated blow air into a preform includes: a high-pressure air sourcefor generating high-pressure blow air; a high-pressure gate valvefor opening/closing a blow air channel on the downstream of the high-pressure air source; a heat exchangerfor heating the blow air on the downstream of the high-pressure gate valve; a throttle valvefor throttling the flow rate of blow air on the downstream side of the heat exchanger; and a switchover valvefor switching the blow air on the downstream of the throttle valve

Blow air supply unit for blow molding machine

An apparatus for supplying synthetic resins applicable to a metal mold wheel that rotates at a high speed. A cutter of a cutter unit and a holding fitting are attached to an air cylinder, so that the cutter unit can be advanced and retreated in the radial direction of rotation. When the molten resin is stably blown out from an extrusion nozzle, the air cylinder is expanded to move the cutter to an advanced position to cut the molten resin. When the molten resin is unstably blown out from the extruder, the air cylinder is contracted and the cutter is arranged at a retreated position so will not to come in contact with the molten resin. Despite the cutter wheel continues to rotate, the molten resin is not contacted by the cutters.
