Claim:
1. A can seaming apparatus comprising: a seaming chuck providing for engagement with a can and lid assembly; a motor engaged with the seaming chuck and providing for the rotation of the seaming chuck around a can axis at a selected rate of rotation; a first seaming arm pivotably secured to a first pivot shaft; a second seaming arm pivotably secured to a second pivot shaft; a first seam roller attached to a first end of the first seaming arm; a second seam roller attached to a first end of the second seaming arm; a first cam system operatively associated with a second end of the first seaming arm, the first cam system comprising a first rotating cam, a first cam follower associated with the first rotating cam, and a first actuator which is physically separate from the motor and powered independent of the motor, the first actuator providing force to move the first seaming arm in a controlled fashion and thereby engage the first seam roller with the can and lid assembly; and a second cam system operatively associated with a second end of the second seaming arm, the second cam system comprising a second rotating cam, a second cam follower associated with the second rotating cam, and a second actuator which is physically separate from the motor and powered independent of the motor, and which is separate from the first actuator, the second actuator providing force to move the second seaming arm in a controlled fashion and thereby engage the second seam roller with the can and lid assembly, wherein the first actuator and the second actuator provide for primary lateral adjustment, perpendicular to the can axis, of the position of the first seam roller and the second seam roller, and wherein the first cam follower and the second cam follower comprise eccentric bases providing for secondary lateral adjustment, perpendicular to the can axis, of the first seam roller and the second seam roller, wherein the secondary lateral adjustment comprises a refinement of the primary lateral adjustment.
