ABSTRACT:
A machine for forming a metal roof panel of indeterminate length from a uniform width supply strip of sheet metal having a pair of parallel straight longitudinal edges. The machine has a series of spaced forming stations each having upper and lower shaping rollers between which the sheet metal strip is passed so as to impart a desired shape to the sheet metal strip which is uniform the length of sheet metal strip after it exits the apparatus. A stamping station located in the path of the sheet metal strip before the series of spaced forming stations is effective to form linear impressions in the sheet metal strip. The linear impressions are transverse to the longitudinal edges of the sheet metal strip, with each such impression having its lateral extent limited such that the succeeding series of shaping rollers do not impinge thereon.
