Abstract
A portable device for guiding a length of pressure sensitive adhesive coated tape partially onto the outer wrap of a roll of masking material adjacent one of its edges to provide a composite masking sheet for use in masking surfaces comprising a length of the sheet material having the tape adhered along and extending widthwise past one edge by which the composite masking sheet can be adhered to a surface. The outer edge of the tape is not guided by the device, and a tendency that otherwise exists for the tape being adhered along the edge portion of the roll of masking material to move transversely away from the masking material so that less and less of the tape is adhered to the masking material is restricted by a tracking member mounted on a frame of the device between a hub supporting a roll of the tape and the roll of masking material. The tracking member engages the rear surface of the tape along its edge that overlaps the masking material for less than the full width of the tape and deflects the tape toward a plane through the axes of the rolls of tape and masking material from a plane which is mutually tangent to the peripheries of the rolls of tape and masking material.
