ようにしたことを特徴とするロール成形装置。 A long rolled first metal plate is formed into a substantially cylindrical shape by roll forming, and both ends of the first metal plate are
An inwardly curved piece is formed by forming the piece in the inward direction and close to the inner surface, and at the same time as this forming process, a second metal plate material that is rolled and narrower and longer than the first metal plate material is formed by roll forming. An inwardly curved locking piece is formed by forming the inwardly curved locking piece into a substantially M-shaped cross section and shaping its both edges so as to be close to the inner surface and to lock onto the inner surface of the inwardly curved piece. The roll is characterized in that, in a state of being locked to the inwardly bent piece of the first metal plate, press pressure is applied from inside and outside to the outer surface side near the inwardly bent piece and the second metal plate so as to bring them into pressure contact. Molding equipment.
