Abstract: A can lid feeder, for use with a can seamer, has a separator for can lids which projects into a drop hole provided in a cylindrical body at the bottom of a hopper and which separates dropped and stacked can lids one by one from the bottom of the stack. A rotary shaft of the separator extends in a gear box which is supported in the feeder in a freely swingable manner. The gear box is swingable so that the separator can move in the radial direction with respect to the cylindrical body having the drop hole. After a side surface of the swinging gear box has been brought into contact with the outer circumferential surface of the cylindrical body, the gear box is fixed in position by a clamp lever.

Abstract: A can seamer for seaming a lid to a can drum filled with liquid and having the lid placed on a top opening includes seaming rolls and a seaming chuck. The time necessary for replacement of the seaming rolls and the seaming chuck, when changing the diameter of the cans to be seamed, is greatly shortened. A seaming lever having the seaming rolls mounted thereon and the seaming chuck are respectively connected to the bottom end portions of a seaming roll shaft and a rotary cylinder via splines or serrations. The seaming lever and the seaming chuck are integrally connected by a connecting bracket.
