Abstract: Method for generating an atmospheric pressure glow plasma (APG), wherein said plasma is generated in a discharge space between a plurality of electrodes.

Abstract: The present invention relates to a method for splicing successive rolls of webmaterial to one endless web, in such way that during subsequent coating of the web, coating defects near the splices are reduced, preferably prevented. To that end at least part of the trailing edge of the splicing tape used to splice the succeeding webs, is left free of adhesive. Because of this, air, which during said coating process gets entrapped behind the splice, between the coating layer and the web, can dissipate between the adhesive-free tape edge and the underlying web surface, thus reducing or preventing the formation of air bubbles and subsequent coating defects. The possible reoccurrence of discontinuity coating defects at very high coating speeds can be reduced or prevented by subjecting the surface of the web to be coated to an electrostatic charge before applying the coating.
