Patent ID: 8263898

Claim:
A device for producing tailored blanks with a workpiece carrier for the sheets ( 15 a , 15 b ) that are to be joined into the tailored blank in the butt joint by welding and with a plurality of laser welding heads ( 14 a , 14 b ) which are arranged one behind the other above the workpiece carrier and along the butt joint seam to be welded and can be moved with an advancing device ( 11 a , 11 b ), wherein the heads can each be aligned with the joint using positioning means, wherein at least two combined laser cutting and welding heads ( 14 a , 14 b ) are carried by extension arms ( 16 a , 16 b ), which are carried by at least two independent arms ( 13 a , 13 b ), which are each associated with independent units ( 11 a , 11 b ) of the advancing device, wherein the extension arms ( 16 a , 16 b ) are designed to be movable on the arms ( 13 a , 13 b ), and in that the positioning means can adjust the distances of the units ( 11 a , 11 b ) in the direction of the butt joint and also the distances of the cutting and welding heads ( 14 a , 14 b ) in the transverse direction to the butt joint wherein the laser cutting and welding heads ( 14 a , 14 b ) are carried by the extension arms ( 16 a , 16 b ) with displacement in the advance direction with respect to the arms ( 13 a , 13 b ) in such way that they can assume a position directly side by side relative to the advance direction or can be readjusted to be in line in the advance direction.
