Abstract: A roll of composite edge trimming tape made by adhering masking tape to filament-bearing adhesive tape. The filament-bearing adhesive tape is made from a double-coated tape having a substrate layer and two adhesive layers. A filament is placed along the length of the masking tape in contact with one of the adhesive layers at equal distances from the edges of the tape. The tape is then folded so that the portions of the tape on either side of the filament are bonded together by the adhesive layer, and the tape surrounds the filament at one end of the filament-bearing adhesive tape. The composite edge trimming tape is formed by bringing the adhesive side of the masking tape in contact with an adhesive surface of the filament-bearing adhesive tape so one longitudinal edge of the masking tape is proximate to the portion of the filament-bearing adhesive tape containing the filament.
