Abstract

PURPOSE:To form periodic concavo-convex form with a small forming device by passing a rotating roller provided with concavo-convex form on the circumference that corresponds to the form for integral period of the concavo-convex form on a band-shaped material. CONSTITUTION:A hooplike band shaped material 1 enters a forming machine 2 after passing a staightener 2. In the forming machine 3, rollers 13, 14 are controlled to have a fixed angular velocity relatively while beig pressed against the band-shaped material by pressure device such as hydraulic cylinders 17, 18, and rotated by a driving device of a motor 19 attached to axes 11, 12. Periodic concavo-convex form is formed on the band shaped material 1 that passed between rollers 13, 14. By the above, forming pressure required is small since forming is made in relatively small area successively. Thus, the forming device can be made small.
