Abstract
An adhesive transfer system for applying a pattern of adhesive to a web of tipping paper as it is being fed through a smoking article filter assembly unit including a transfer roller and an applicator roller, the transfer roller having an engraved pattern on its surface that corresponds to the pattern of adhesive to be applied to the tipping paper web, the applicator roller being nipped with the transfer roller so that adhesive received on its surface is transferred from said engraved region onto the applicator roller as the transfer roller and applicator roller rotate to form an adhesive pattern on the applicator roller for subsequent transfer onto a moving web of tipping paper in contact with said applicator roller, where the engraved pattern includes individual adhesive containing cells to break up adhesive that coats the engraved region of the transfer roller.
