Abstract

PURPOSE:To direct the flow of a sheeted continuous body extruded from an extruder to a molding machine while changing it intermittently by providing a dancer roll capable of adjusting the running length of the sheeted continuous body between the extruder and the molding machine. CONSTITUTION:A change in the length of a sheet S between a molding machine 24 and an extruder 12 due to the stoppage of the flow of the sheet S in the molding machine 24 is absorbed by the lowering of a dancer roll 20. After the molding of the sheet S absorbed by the dancer roll is finished, the sheet S is taken by a pair of rolls 22 and then sent to the molding machine 24 by a chain conveyer 30 for transportation, where it is molded into the shape of a given molding 32.
