Method for producing a seam using a bending machine, and bending machine configured for this purpose

Abstract

A method for producing a seam on a workpiece made of flat material using a bending machine is disclosed. The bending machine comprises a first clamping jaw, a second clamping jaw that is mounted movably relative to the first clamping jaw and configured to clamp, together with the first clamping jaw, the workpiece, and a bending unit that is arranged on one of the clamping jaws and has a bending tool, the bending unit being configured to bend a portion of the workpiece by moving the bending tool relative to the associated clamping jaw to form a fold. The method comprises producing a pre-seam on the workpiece, comprising forming a first fold, and closing the pre-seam to form a seam by closing the first fold with the bending unit in a state in which the other of the clamping jaws is spaced from the seam.
