Abstract
PURPOSE: To achieve improvement in the precision of corrugated sheet by molding sheet into corrugated form with punch having a large diameter R.
CONSTITUTION: When molding any object into corrugated form with a punch having a large diameter R, the tensile strength of A, A' works towards the corrugated section direction. Inasmuch as the punch 7 is provided with R, the tensile strength of B, B' works towards the width direction of the corrugation. Said tensile B, B' functions to offset the spring back force against A, A' of the sectional direc- tion, thereby minimizing variance of the pitch precision in forming a single corrugation.
