ABSTRACT:
To change the surface tension of cup-like containers by means of corona treatment, the containers are placed on a mandrel and are moved by drive wheels in such a way that the cup-like container is caused to roll off on the mandrel with the inside of the wall. Via an electrode the discharge current is supplied across the discharge gap to the cup-like container and it is removed via the mandrel, which is connected as counter-electrode. To avoid a discharge gap on the inside of the wall, the mandrel has connected to it a guide shoe which always applies against the inside of the wall.
