Abstract
Abstract A method of improving the surface activity of electrically conductive carrier strips, to enhance their bonding properties. The surface of the strip is subjected to a high frequency and high gradient alternating electrical field formed between two electrodes. The carrier strip which forms one electrode is conducted over and in direct contact with a roller electrode which forms the other electrode and the surface of which comprises a solid dielectric material. The difficulties which occur when an air gap is present between the strip and the electrode are thereby avoided.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
51 words
A method as claimed in claim 1, wherein the carrier strip is passed over and in direct contact with at least two of said electrode rollers rotating in opposite directions, in such manner that one of its surfaces contacts one roller and the other of its surfaces contacts the other roller.
Claim 2
Dependent Claim
38 words
A method as claimed in claim 1, wherein the strip is passed over and in contact with a plurality of rollers rotating in the same direction in such manner that only one of its surfaces contacts the rollers.
Claim 3
Dependent Claim
34 words
A method as claimed in claim 2, wherein the strip is passed over more than two rollers rotating alternately in opposite directions in such manner that adjacent rollers contact opposite sides of the strip.
Claim 4
Dependent Claim
12 words
A method as claimed in claim 1, wherein the strip is aluminum.
