Abstract
A method removes a follower plate of a device for transporting viscous material out of a barrel-like container. The device has the follower plate for closing the container, which is open at the top and has a container base and a container casing extending upwards from the base, the follower plate being movable toward and away from the base. A force measuring sensor measures a force exerted by a container onto a placement surface; the controller switches the ventilation mode to the lifting mode if the force exerted by the container onto the placement surface exceeds a first target force value; and the controller switches the lifting mode to the ventilation mode if the force exerted by the container onto the placement surface falls below a second target force value, and/or the at least one sensor measures the position of the container relative to a stationary point.
