Transport installation and method of transporting can bodies for a fully automated resistance welding machine

Abstract From the Canadian patent

A transport installation for can bodies for a fully automated resistance welding machine comprising a roll former station for rolling the bodies two successively, arranged driven transport systems and a pair of welding, electrodes. The transport systems comprise endless revolving chains equipped with fixed catches or cams and defining first and second chains. The first chain passes through the roll former station where, during rolling of the blanks into the can bodies, it cyclically and periodically remains at least approximately stationary whereas, the second chain has a sinusoidal velocity course. The can bodies exposed to the intermittent non-continuous mode of operation of the first …
