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.

Method and device for forcibly inserting drop into compression molding machine, and molding die follow-up type method and device for supplying drop

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 articlesconveyed passing through a predetermined conveyer passage, a cooling liquid is blown next thereto, and a gas stream is further blown thereto.
