ABSTRACT:
A strip welding machine for butt-welding cut surfaces of a strip beginning and a strip end of metal strips to be connected is described. The welding seam is manufactured with a laser welding head. In order to obtain a plane and parallel and gap-free butt joint of the cut surfaces, two separately mounted cutting tools are provided. Each cutting tool has an upper knife and two lower knives, wherein each upper knife is moved virtually without a gap between the two lower knives. Consequently, the cut surfaces at the strip end and the cut surfaces at the strip beginning of the metal strips to be connected are manufactured with equal cutting forces, so that dimensional inaccuracies cannot occur.
