PURPOSE: To execute continuously a lot of roll-working and draw-working by one set of machine device, by providing a means for holding both ends of a blank and driving a reciprocating motion, plural groups of rolling rolls wich are made to press-contact and are separated to and from both faces of the blank and a die supporting means which advances to a position of the blank executing the reciprocating motion, and shunts.

CONSTITUTION: Both ends of a blank 4 are held by a pair of holding means 15, the blank 4 is heated by supplying a high frequency current to a heating coil and cooling nozzle 23, an upper roll 2 and a lower roll 3 are driven to execute a reciprocating rotation, the blank 4 is subjected to one end half reciprocating motion, and rolling of three stages is executed. In case of this rolling operation, a pair of drawing-out tables 12 are moved in the rolling direction by rotating a chain 18, and tension is provided to the blank 4 by a pair of tension balancing oil pressure cylinder 13. When the roll-working is ended, the blank 4 is made to pass through a die supported by a die supporting base 24, and draw-working is performed by driving the chain 18.
