Abstract

PURPOSE:To prevent the gelation and adherence of a thermosetting resin composition in a die, by maintaining the temperature of the introductory part higher than the melting point (T) of the resin and the temperature of the land part lower than T, using a die wherein the introductory part is thermally insulated from the land part. CONSTITUTION:A thermosetting resin composition is melt kneaded by the screw 2 rotating at a desired rotational speed in the cylinder 1 of the extruder, and extruded through the die 3, divided into the land part 4 and the introductroy part 5 by the heat insulating material 7, continuously. The part 5 is maintained at a higher temperature than the melting point (T) of the resin; the part 4, at a temperature of T to (T-40 deg.C).
