Document Type and Number:
WIPO Patent Application WO/2014/171221
Kind Code:
A1
Abstract:
A first roll (20) and a second roll (40) of a roll forming device are provided with a plurality of cutting blades (22, 122) that are laminated and retainers (21, 121) that pass through the plurality of laminated cutting blades (22, 122) as well as passing through a first rotating shaft (16) and a second rotating shaft (18). When the plurality of cutting blades (22, 122) are laminated onto end parts of the retainers (21, 121), protrusions (21a, 121a) that control positioning work for the cutting blades (22, 122) are provided. With this constitution, when the plurality of cutting blades (22, 122) are joined in a laminated state to the plurality of retainers (21, 121), control of the cutting blades (22, 122) in the direction of lamination is easily possible using retainers (21, 121).
