METHOD AND APPARATUS FOR A TAPE-REWINDING SUBSTRATE CLEANER

摘要

A cleaner assembly for cleaning a roller (12) comprising a tape unwinder and winder (272a, 272b) for holding and dispensing adhesive tape (242) which may be a continuous strip or may comprise discrete sheets of adhesive tape wound on top of each other. The winder and unwinder are connected to a drive by a timing belt (282). Thus a length of tape may be wound back and forth on a roller surface by alternating the rotation of the drive (278). The tape is passed around a backing roller to press the tape against a roller to be cleaned. In a second embodiment, the tape roll comprises a plurality of sheets of tape wound on top of each other. To remove a spent outer sheet, the outer sheet carrying the transferred particles is transferred to a continuous tape roll, exposing a fresh sheet on the sheeted tape roll which is then ready for renewed cleaning service.
