Abstract

A thermoform packaging machine comprising, as work stations, a forming station for thermoforming troughs in a packaging film, at least one sealing station for sealing the troughs with a cover film, and a cutting station as well as a feeding device for causing a feed of the packaging film. A method for using such a thermoform packaging machine wherein a controller determines for two or more work stations, prior to a process step, which required feed length each of these work stations has, the required feed length indicating the distance by which the packaging film will have to be conveyed for the next process step of the respective work station, before a feed length specification is ascertained from the required feed lengths determined and the feeding device is controlled accordingly.
