ABSTRACT:
A portable, hand-held tool for rolling a flange on metal sheet comprises a pair of handles pivoted together, the handles bearing a pair of parallel rollers which are moved together on approach of the handles and are drivable in rotation, the rollers having opposed portions of greater and lesser diameter so that on clamping of a metal sheet edge between the rollers and rotation of the rollers a flange is formed in the sheet edge. The handles may carry a device for setting the separation of the rollers at a desired value.
