とを有することを特徴としている。An apparatus for molding a resin material of the present invention into a sheet form is a conical twin-screw extruder in which the tip of a rotor shaft is inclined downward by a predetermined angle, and the tip of the screw extruder. It has a large-diameter lower rolling roll arranged near the lower end of the opening, and a small-diameter upper rolling roll arranged at a distance from the upper end of the tip opening of the screw extruder. It has a feature.

に、装置内に残る材料がなく、清掃作業が簡易になる。When the high-viscosity material kneaded by the kneader at the front stage of the apparatus of the present invention becomes a lump and is put into the inlet of the extruder of the present invention, the extruder continuously feeds this from the tip opening portion in fixed quantity. The material is accumulated in the reservoir of the present invention. At this time, the pair of rolling rolls are rotationally driven to extrude the sheet-shaped preform. The storage part absorbs the unevenness of the discharge amount of the screw extruder and serves a buffer function to constantly supply the material to the rolling rolls. Since the screw extruder has the tip inclined downwards, there is no material left inside and the material in the reservoir is on the lower rolling rolls, so all of it is extruded from the rolling rolls, thus one lot There is no material left in the device after the end of the work, and the cleaning work is simplified.

に簡単化された。According to the present invention, the material is formed on the large-diameter lower rolling roll 2b only by the tip opening 11 of the extruder 1 and the small-diameter upper rolling roll 2a without interposing any member. Since the storage part is configured, the number of parts is reduced as much as possible and the manufacturing cost is reduced. Furthermore, the die or nozzle used in the conventional extrusion molding method is no longer required, and even after the material in the extruder 1 is exhausted, the rolling rolls 2a and 2b are continuously driven to rotate until the material in the storage portion is exhausted, and The material can be discharged without leaving any residue, and the cleaning work of the residual material at the end of sitting work and at the time of material switching is greatly simplified.
