Abstract
A method for monitoring a tubular bag machine having a drive control system and independently controlled electronic drive units controlled by a drive control system for driving functional elements of the packing machine in a cycle time-synchronous manner in predefined motion sequences, one drive unit being a transverse sealing unit with a drive motor and two transverse sealing jaws for transversely sealing a film tube, and the drive motor torque measured using a drive controller, and the drive motor position measured using a position sensor, the method including moving the film tube into the sealing zone between the transverse sealing jaws, closing the jaws according to a predefined target torque stored in the drive control system, measuring the actual position of the drive motor upon reaching the target torque, and comparing the measured position to a target position stored in the drive control system associated with the predefined target torque.
