Abstract: The present invention relates to a work station for a packaging machine, comprising an upper tool and a lower tool arranged below the upper tool. These tools are configured for acting on a packaging web. A lifting unit is able to move the upper tool and/or the lower tool such that, at a specific position, the two tools abut on one another or are only spaced apart at a small distance. According to the present invention, the two tools are adapted to be coupled to one another by a releasable coupling at this position so that they can be removed from the work station in common. The invention also relates to a corresponding method for removing a lower tool from a work station, e.g. for the purpose of tool exchange.
