Web cleaning apparatus

摘要

A tape cleaner head that has an arcuate surface around which tape is wrapped. The body of the cleaning head has an opening formed therein, the opening being shaped so as to form first and second knife edges at a point where the arcuate surface is in contact with the tape. The knife edges provide scraping surfaces to the tape regardless of the direction of travel of the tape over the cleaning head to thereby remove foreign particles from the tape surface to prevent signal disturbance and form a cavity to entrap the particles and remove them from the system.
