Device for treating track, sheet or plate-shaped substrate with electric corona discharge, has suction device that sucks out air between substrate and support surface with air suction opening(s)

摘要

The device has a treatment electrode and a counter electrode forming a treatment gap between them in which the substrate (3) can be placed and a substrate support element with a substrate support surface (8). A suction device (10) sucks out the air between the substrate and the support surface, which has at least one air suction opening.
