Abstract
The invention relates to a method for reducing end face stickiness of a roll (1) of adhesive tape, by supplying a precursor (18) to a plasma stream (20), using the plasma stream (20) enriched with the precursor (18) to coat a carrier film (2) with a passivation coat (3) in a plasma process, placing a carrier film section (5) by its passivation-coated side onto an end face (4) of the roll (1) of adhesive tape, removing the carrier film section (5) and leaving at least part of the passivation coat (6) on the end face (4) and reducing its end face stickiness.
Claims11
A method for reducing end face stickiness of a roll of adhesive tape, comprising:
- supplying a precursor to a plasma stream,
- using the plasma stream enriched with the precursor to coat a carrier film with a passivation coat in a plasma process,
- placing a carrier film section by its passivation-coated side onto an end face of the roll of adhesive tape, and
- removing the carrier film section and leaving at least part of the passivation coat on the end face and reducing its end face stickiness.
