ABSTRACT:
A welder for welding side seams of tubular bodies. The welder has a body feed in the form of a single conveyor which serves to receive bodies at regular intervals from a rounded unseamed tubular body supply and to move the bodies into a welding head nip with the bodies being initially widely spaced and then the gap between a body in the welding head and a trailing body being rapidly reduced so that the leading edge of a following body enters into the nip at the same moment as the trailing edge of a leading body begins to depart from the nip, with the adjacent edges of adjacent bodies being in substantially touching but positively spaced relation.
