ABSTRACT:
A two-sided adhesive tape comprising first and second single-sided adhesive tapes connected to one another by a bridge member. Each single-sided adhesive tape comprises an elongated strip of flexible material having lengthwise extending lateral edges, an adhesive side surfaced with adhesive, and a back side not surfaced with adhesive. The bridge member comprises an elongated strip of flexible material having lengthwise extending lateral edges. The single-sided adhesive tapes are positioned in edge-to-edge relationship to one another, such that their inner lateral edges are adjacent to one another with the adhesive sides of the single-sided adhesive tapes facing in opposite directions. The bridge member extends between the single-sided adhesive tapes. In one embodiment, the bridge member is adhesively joined to the adhesive sides of the single-side adhesive tapes. In a second embodiment, the bridge member includes an adhesive surface, the adhesive surface of one lateral edge of the bridge member is joined to the adhesive surface of the first single-sided adhesive tape, and the adhesive surface of the second lateral edge of the bridge member is joined to the back surface of the second single-sided adhesive tape. Apparatus and method for making such two-sided adhesive tape are also disclosed.
