Can seamer.

摘要

The known can seamer in which a can drum filled with liquid and having a can lid placed on the opening at the top is subjected to seaming work by means of seaming rolls and a seaming chuck, is improved so that a replacement time for the seaming rolls and the seaming chuck in the case of changing the diameter of the cans can be greatly shortened. The improvements reside in that a seaming lever (14) having the seaming rolls (11 and 12) mounted thereon and the seaming chuck (13) are respectively connected to the bottom end portions of a seaming roll shaft (15) and a rotary cylinder (21) via splines or serrations (15a and 22), and the seaming lever and the seaming chuck are integrally connected by means of a connecting bracket (27).
