Abstract
A seaming shaft mechanism for a sealer for the attaching of a can lid to a can body includes a seaming shaft rotatable around a seaming axis, a seamer arranged at one end of the seaming shaft; as well as a sensor for the monitoring of the seaming process during the attachment of the can lid to the can body. The sensor is arranged at the seaming shaft such that the seaming process can be monitored by the sensor via a measurement of a displacement of the seaming shaft relative to the seaming axis or via a measurement of a torsion of the of the seaming shaft.
