Abstract
A double-ended, drum seaming machine--which includes spaced, bed-supported columns carrying drum-engaging rotary chucks and drum seaming units--embodying a structural arrangement, in association with included stripper rods, which provides for pre-adjustment of the relative positions of the columns on the bed (according to drum length), and for predetermination of the limited-travel, working stroke of the individual columns between a retracted clearance position and an advanced position with the corresponding rotary chuck in drum head engagement.
