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 in a clamping plane, 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 such that it is located in an area in front of the clamping jaws, comprising forming a fold, wherein the pre-seam extends at an angle relative to the clamping plane, and changing the angle by displacing the bending tool.

Bending machine with a machine bed including a workpiece table with a workpiece support surface and an upper tool which is linearly movable mounted to the machine bed along a movement axis and which has a bottom edge arranged adjacent to the workpiece support surface. The lower edge and the movement axis define a movement plane which separates a handling space from a workpiece receiving space, in which a first optical safety device is arranged in the handling space and a second optical safety device is arranged in the workpiece receiving space, and with a safety controller to process sensor signals from the optical safety devices and for switching off a drive associated with the upper tool. The safety controller provides a first operating mode, in which only the first sensor signals are processed, and a second operating mode, in which only the second sensor signals are processed.

A device for manufacturing a metal wheel (1) from a pre-form, with stretching rolls (3) engaging on the rim region of the pre-form, by means of which rolls a rim (1.1) is end-formed which, for forming a rim flange (1.7). Freely rotatable rolls (4) are arranged underneath the stretching rolls (3) and cooperate with them. A method for manufacturing a metal wheel (1) from a pre-form, the pre-form of the metal wheel (1) to be manufactured is placed on a clamping mandrel (2) and is caused to rotate, stretching rolls (3) engage an axially outer side of a rotation-symmetrical jacket of the pre-form with the exertion of radial pressure, and move along the jacket wall of the pre-form with compression and stretching of the jacket wall to form a rim (1.1) with a main movement component parallel with the axis of rotation (2.1) of the pre-form.
