Abstract
A method for producing can bodies made of sheet metal for the manufacture of cans includes a step of bringing together and placing one on top of the other of two sheet metal strips. The sheet metal strips, which are placed one on top of the other, are joined by means of several joint welds which extend continuously in the longitudinal direction of the strip through continuous moving of the sheet metal strips past a laser welding device which has several laser heads arranged at corresponding mutual spacings. The sheet metal strips, which are welded together, are longitudinally cut by laser cutting along each weld joint in order to produce several adjacent flat tubes. The welding and the longitudinal cutting are effected simultaneously with one laser head respectively.
