ABSTRACT OF THE DISCLOSURE An arrangement for profiling forwardly indexed material webs for producing e.g. parallel, transverse undulations in a sheet metal web of uniform width which is forwardly indexed through a forming space located between a lower bed having a die with an upwardly turned forming surface and a holding device located above the forming space and carrying a punch mechanism reciprocatingly driven relative to the die and executing a forming stroke while engaging the web and the forming surface of the die. An inclined ramp guides the in- coming web obliquely downwards towards the forming location on the forming surface. Close to the ramp is a web support body yielding transversely to the plane of the ramp when the web is stretched over the body during profiling by the forces of the punch mechanism located beneath the holding device which is formed as an attachment plate movable in relation to the bed and has a punch tool extending from the plate and a holding punch axially movable along the punch tool and mounted on guide means attached to the plate and held forwardly biased in an outwardly protruding position by spring devices acting between the plate and the holding punch.
