A METHOD TO MECHANICALLY PRODUCE A REPEATABLE SEAM IN A CAN

摘要

A can seaming apparatus and methods of forming a seam on a can and lid assembly is disclosed. The apparatus comprises one or more seaming arms pivotably attached to a shaft, a seam roller attached to one end of each seaming arm and a cam system. The cam system comprises one or more cams associated with the end of each seaming arm opposite the seam roller. Force is transferred to each seaming arm through rotation of the one or more cams. The seaming arm then pivots and moves the associated roller into a seaming area of a can and lid assembly to create a seam.
