Claim 9

Dependent Claim 40 words

The combination as set forth in claim 6 wherein the second flange has an outlet opening through which the mask layer, the adhesive layer and the mask section are fed during tape dispensing after the release strip is separated therefrom.

Claim 10

Dependent Claim 43 words

The combination as set forth in claim 8 further including a roller guide disposed adjacent the outlet opening toward the mask layer side of the tape and a cutting edge disposed adjacent the outlet opening opposite the mask layer side of the tape.
