APPARATUS FOR ROLLING CURVED SECTIONS Abstract of the Disclosure A metal sheet is formed into an arcuate contour by rolling the sheet under high pressure on an elastomeric pad (24) supported by a rigid frame. A pair of laterally spaced rollers (30, 32) are used to form the arc. Each moves from the transverse edge of the sheet inwardly and crosses the center line of the sheet. Under the high pressure applied to the rolls the sheet yields to form the arc and the elastomeric material elastically deforms as the arc is formed. The rollers depend from vertical guides (34, 36) which follow a track extending transversely across the sheet. A guide track (38) is provided in a transverse beam located above the rolls and the guides. Hydraulic or pneumatic jacks (70) apply pressure to the beam which in turn applies pressure to the rolls.
