Abstract: 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.

Abstract: A method and device for continuously supplying molten synthetic resin 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.

Abstract: 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.

Abstract: An apparatus for cooling preformed articles, which is capable of very effectively cooling the preformed articles and is, further, capable of sufficiently suppressing or preventing the preformed articles from being locally damaged as a result of coming in contact with each other as they are conveyed neighboring one another in a state of not yet fully cooled. A spray is blown onto the preformed articles 34 conveyed passing through a predetermined conveyer passage 42, a cooling liquid is blown next thereto, and a gas stream is further blown thereto.
