APPARATUS FOR PRODUCING EXTRUSION MOLDED PLATE

摘要

PROBLEM TO BE SOLVED: To enhance the dimensional accuracy or quality and productivity of a hollow extrusion molded plate having a pattern transferred to the surface thereof. SOLUTION: A pattern transfer roll 3 is arranged to the upper part of the extrusion orifice of an extrusion mold 1 of a hollow molded plate 2 and an extrusion auxiliary support roll 4 of a molding material is arranged at the lower part thereof. Drive means 30, 40 for individually rotationally driving both rolls 3, 4 rotated in synchronous relation to the extrusion speed of the molded plate 2 are provided. By this constitution, the pattern transfer roll 3 and the support roll 4 can be set to different speeds.
