Claim 7:
8. A method for controlling a drive unit of a foil transport device which supplies, at a packaging machine during a production run taking place thereat, a foil with a predetermined foil tension to a workstation of the packaging machine, wherein the drive unit is controlled, during the production run of the packaging machine, based on a speed- and/or temperature-dependent friction moment characteristic curve detected by means of a rotationally driven measurement run carried out by the drive unit; and
wherein a controlling system determines, based on a friction moment-temperature characteristic curve stored to the controlling system for the drive unit, a temperature compensation factor for activation of the drive unit in view of an operating temperature of the drive unit currently detected during the production run and in view of a measurement run temperature detected during the measurement run.
