<p>PROBLEM TO BE SOLVED: To certainly prevent the generation of excess or shortage of storage while achieving the miniaturization of an apparatus or molding line by minimizing the storage capacity of an accumulator part. SOLUTION: The accumulator part is provided to the molding line for using the strip continuously extruded from an extruder to mold the same into a product by a molding drum. When a molding time for molding the product by moving the molding drum is set to Tw, the standard extrusion speed during the molding time Tw of the strip from the extruder is set to Vw, the standard extrusion speed during a stop time is set to Vr and the standard supply speed of the strip to the molding drum is set to VO, formula (1): VO=(Vw×Tw+Vr+ Tr)/Tw is formed. The residual amount J in the accumulator part is measured, at each time when one molding of the product is completed, to obtain the difference F (=S-J) with standard storage quantity S and, during the stop time Tr, the molding drum is operated at the adjusted extrusion speed Vnr calculated by formula (2): Vnr=F/Tr.</p> |
