Abstract
A method for operating a tubular bag machine with a drive control system and multiple electronic drive units controlled independently of each other for driving functional elements of the packing machine in a cycle time-synchronous manner through predefined motion sequences, one drive unit being a transverse sealing unit with a drive motor driving two transverse sealing jaws for transversely sealing a film tube, and at least conversion functions for converting the drive torque and the position of the drive motor into the sealing force between the transverse sealing jaws being stored or calculated in the drive control system, the method including determining the operating temperature of the transverse sealing jaws, selecting or calculating a conversion function as a function of the operating temperature, using the temperature-dependent conversion function in calculating the drive torque of the drive motor required to reach a desired target sealing force between the transverse sealing jaws.
