ABSTRACT:
A roll bender machine for bending metal sheets which includes a roller driven in rotation and about which the sheet metal is rolled and at least two backing rollers adapted to receive and bear against a sheet while it is being bent around the roller. The backing rollers are mounted to rotate on a support that is adjustable. The bending roller and backing rollers are each associated with at least one set of devices for compensating their deflection. An arm is mounted on the machine for receiving coiled sheet metal and is provided with a housing in which the bending roller is at least partially received.
