Abstract
An automated system and method for applying thermoplastic adhesives to work pieces from a roll of adhesive segments applied to an adhesive segment-laden carrier release tape. The present invention may be implemented in a system that automatically advances the adhesive segment-laden carrier release tape to position an adhesive segment thereon in the apparatus for application thereof to a work piece. Accurate indexing and advancement of the adhesive segment-laden carrier release tape preferably is provided by optical indexing of the carrier release tape, e.g., by the optical detection of a transverse line or other index marking printed or otherwise provided on the adhesive segment carrier release along with the adhesive segments deposited thereon.
