Abstract

PURPOSE:To reduce the load of the upper and lower roll stands as well as the slip between a side roll and a material to be molded and as a result to reduce the roll marks of the material to be molded and the roll friction, by feeding an input through the shafts of the upper and lower roll stands to drive the side roll. CONSTITUTION:A chain sprocket 17 is adhered to an upper roll shaft 5 to be driven, and the sprocket 17 and a chain sprocket 16 of the side roll side are driven via a chain 18. The driving force of the shaft 5 is transmitted to side rolls 7 and 8 via the sprocket 17, the chain 18 and a warm gear set, respectively. As a result, the roll friction due to nondriving of the side roll can be eliminated with no supply of undesired motive power. Thus the molding process is smoothly carried out as desired.
