Abstract
The invention concerns a device for shaping a pulley blank, in particular for making poly-V profiles. A sheet metal object is surrounded by an annular tool (7) mounted eccentrically on an inner cam located on an outer cam (14). The outer cam (14) rotates coaxially about the central axis of the sheet metal object (1). The annular tool is moved radially outward by a movement of the inner cam relative to the outer cam, and engages with the sheet metal object, on which it unwinds while executing an eccentric rotatory movement around it.
