COMPOSITE EDGE TRIMMING TAPE

摘要

The present invention is an composite edge trimming tape made by adhering masking tape to filament-bearing adhesive tape. The masking tape has a substrate layer and an adhesive layer. The filament-bearing adhesive tape is made from a double-coated tape that has a substrate layer and two adhesive layers, one being on either side of the substrate layer. A filament is placed along the length of the masking tape in contact with one of the adhesive layers at the middle of the tape at equal distances from the two edges of the tape running longitudinally along the length of the tape. The tape is then folded over 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 one of the adhesive surfaces of the filament-bearing adhesive tape so that one longitudinal edge of the masking tape is proximate to the portion of the filament-bearing adhesive tape containing the filament.

主权项

1. An composite edge trimming tape comprising:
a filament-bearing adhesive tape comprising an elongate substrate folded onto itself so as to form a folded edge, the folded substrate having a first exterior surface and a second exterior surface opposite the first exterior surface, the first exterior surface having adhesive on at least a portion thereof, and a filament enveloped and releasably secured within the substrate along the folded edge and between the first and second exterior surfaces, the filament-bearing adhesive tape having a distal edge opposite the folded edge and having a width being the distance between the filament and the distal edge; and a masking tape comprising an elongate substrate and an adhesive layer, the masking tape having a width greater than the width of the filament-bearing adhesive tape and having first and second edges, a portion of the adhesive layer of the masking tape adhesively attaching the substrate of the masking tape to the second exterior surface of the filament-bearing adhesive tape with the first edge of the masking tape being proximate to the filament.
