Abstract

PURPOSE: To improve the accuracy of spiral spacings by adding tensile force to one end of a strip plate and controlling its amount by winding radii.
CONSTITUTION: In winding a strip plate around a core metal, tensile force T may be obtained by beforehand obtaining the β-σ curve with a winding radius R0 as a parameter (where β: spring-back amount, σ:tensile force per unit area to be applied to the strip plate) and obtaining σ of such a magnitude at which the strip plate after it has sprung back upon removal from the core metal becomes the specified shape and multiplying this by the sectional area of the strip plate. Thereby, the spiral product of good accuracy is obtained with high efficiency.
