Abstract: The invention relates to a method for butt welding metal sheets (1, 2), preferably sheet metal strips or blanks of differing thicknesses by the relative displacement of a laser beam or electron beam in relation to the metal sheets (1, 2), along the line of contact of said sheets (1, 2) or the line of the welding seam that is to be produced, with the aid of tension rollers (4, 5, 10) that are located in pairs at a distance from one another above and below the sheets (1, 2) in the vicinity of the welding seam. The tension rollers (10) that are located above the sheets (1, 2) roll off the latter (1, 2) in a height-adjustable and/or sprung manner. The height of the tension rollers (4, 5) that are located below the sheets (1, 2) on at least one side of the welding seam is adjusted.

Abstract: A device and a method for guiding bands to be joined to one another along their longitudinal edges, in which bands are guided via deflection rollers to a joining position. The device according to the invention provides that the deflection roller located closer to the joining position is configured as a conical roller, the deflection roller arranged upstream of this conical roller in the running direction of the band being also configured as a conical roller or as a deflection roller having a cylindrical lateral surface, and the conical roller last mentioned tapering in the direction of the other longitudinal edge of the band, or the rotational axis of the deflection roller having a cylindrical lateral surface spatially approaching the rotational axis of the conical roller arranged downstream in the running direction of the band on the edge side of the band opposing the longitudinal edge to be joined.
