Device for shaping edge of metal sheet, comprising cutting elements adjustable regarding cutting angle

摘要

The unit (10) comprises an upper (3.1) and a lower cutting element (3.2) rotating in bearings attached to vertical stands (4.1,4.2) exceeding from a base (4) mounted on top of a linear moving carriage (20, 23). The base (4) can be rotated (17) and axially moved (16). The cutting angle can be adjusted in relation to the sheet (8) to be processed resulting in a particularly shaped edge. These patterns can also be created along the edges of a flange or a vertically positioned sheet (8).
