PURPOSE:To make it possible to perform the alteration of a product without stopping an extruder operation, by performing the finish molding of a roughly molded rubber material having a volume corresponding to the finished molded member extruded from an extrusion head while passing the same between a pair of molding rolls. CONSTITUTION:A rubber material 1b having a rough shape extruded from a die 3 is meshed in a molding roll apparatus consisting of a drive roll 8 and a follower roll 9 and subjected to finish molding while passed through an orifice mold formed between both rolls 8, 9 to form the rubber material 1a having the finished shape while this rubber material 1a is passed through a vulcanization apparatus 5 to receive vulcanization treatment. Even in altering a rubber member product, it is unnecessary to replace the die 3 and the exchange of the roll apparatus can be simply performed while the rubber material is continuously moved without stopping the operation of the extruder and, therefore, production efficiency is enhanced. |
