ABSTRACT:
A bending press has a drive mechanism for effecting vertical movement of a bending tool in a bending line, a drive actuating device, and a locking mechanism for the actuating device. A stop assembly behind the bending line includes a rail, a rail drive mechanism to move the rail perpendicularly to the bending line, and at least two stops on said rail. A releasable clamping mechanism fixes the stops in position on the rail, and the stops are movable along the rail upon release of the clamping mechanism. A clamp locking mechanism locks the clamping mechanism in a clamp fixing position. The stop assembly is movable into a position in which the stops project over the bending line when the drive locking mechanism is actuated, and the clamp locking mechanism is actuatable to release the clamp locking mechanism when the drive locking mechanism is actuated.
