Abstract
An apparatus is disclosed for continuously forming and laser welding metal can bodies and the like. The apparatus comprises a former for successively forming flat sheets of metal into generally tubular shaped sheets of metal having longitudinally extending edges to be welded, an indexer for successively advancing the generally tubular shaped sheets of metal from the former to a first position in a direction toward a laser welding device such that the generally tubular shaped sheets of metal are moving at a predetermined speed at the first position, an additional advancing device including a pair of endless metal belts extending between the first position and a second position, the belts having a plurality of fingers mounted thereon in spaced relationship for engaging the trailing ends of successive generally tubular shaped sheets of metal to advance the sheets from the first position to the second position at a substantially constant speed, and a laser welding device arranged for welding the longitudinally extending edges of the generally tubular shaped sheets of metal as they are advanced between the first and second positions.
