Document Type and Number:
WIPO Patent Application WO/2022/172950
Kind Code:
A1
Abstract:
Provided are a manufacturing device and a manufacturing method with which it is possible to manufacture an arcuate roll molded component having an outer contour of a uniform curvature and an inner contour of a variable curvature, an outer contour of a variable curvature and an inner contour of a prescribed uniform curvature, or an outer contour of a variable curvature and an inner contour of a variable curvature. A control unit 104 acquires, as the displacement amount of a bending roll 103 in the width direction during roll bending processing, a third displacement amount corresponding to the sum of a first displacement amount and a second displacement amount of the bending roll 103.
