ABSTRACT:
Method for preparing a tape having a backing bearing on at least one major surface thereof a plurality of ribs disposed substantially longitudinally thereon, and further bearing on at least one major surface thereof a layer of adhesive. The ribs are joined to the backing such that there exists a notch-like separation between each end of the rib and the surface of the backing. No more than 50% of the cross-section of the ribs should project from the rib-bearing surface of the tape. It is preferred that the adhesive be a pressure-sensitive adhesive. The tape of this invention can be prepared by means of coextrusion techniques.
