In the can seaming process (Fig. 1), the filter housing and lid are held between chuck and lifter, and then rotated before the lid is pressed against the seaming roll to carry out seaming. There are two types of seaming roll : 1st roll and 2nd roll.
The first roll approaches the filter lid, and rolls up the lid curl and body flange sections of the can before retreating. Next, the second roll approaches to compress the rolled-up sections to end the seaming.
In other words, the 1st roll rolls up the can lid and can body, doing mainly the bending work; while the 2nd roll compresses the rolled-up sections, and mainly does the seaming work.
