PURPOSE:To roll continuously an irregular shaped metallic plate with high accuracy by inserting the metallic plate between a stationary die and a planetary rolling roll, pressing and rolling the planetary rolling roll to the stationary die side and exerting take-off force onto the metallic plate. CONSTITUTION:The metallic plate 1 wound on a feed drum 18 is fed from a pushing roll 13 to the gap between a stationary die 8 and a work roll 9 and after the plate is expanded by the same, the plate is taken up on a take-up drum 19 via a take-off roll 14. The positive drive of a backup roll and the pushing force by the roll 13 or the take-off force by the roll 14 are utilized for feeding the plate 1 to the die 8 side. The plate 1 is expanded transversely by receiving the restriction from the V-shaped plateau part of the fixedly disposed die for expansion. On the other hand, the expansion effect on a thick-walled part 2 from the roll 10 is blocked by the groove part for leaving the thick wall part, by which the desired thick wall part 2 is continuously formed along the longitudinal direction of the plate 1. |
