Abstract
A method for testing a tubular bag machine, the tubular bag machine having multiple electronic drive units controlled independently by a drive control system for driving functional elements of the packing machine in a cycle time-synchronous manner during predefined motion sequences, one drive unit being a transverse sealing unit comprising a motor and two transverse sealing jaws for transversely sealing a film tube, the drive torque being measured using a drive controller, and the position of the drive motor measured using a position sensor, by removing the film tube from 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 at the target torque; and comparing the measured actual position to a target position stored in the drive control system and associated with the predefined target torque.
