Abstract
An apparatus for double seaming an end unit to a can body includes, as is conventional, a double seaming chuck, a double seaming roll and a mechanism for selectively moving the double seaming roll toward the double seaming chuck to perform a double seaming operation. Most advantageously, a drive mechanism is provided for driving the double seaming chuck and the double seaming roll at respective speeds that are selected so as to reduce relative rotational speed between the double seaming roll and a workpiece when the double seaming roll comes into contact with the workpiece during the double seaming operation.
