Doubled sided pressure sensitive adhesive

Claim 1

A roll of double-sided, pressure-sensitive, adhesive tape comprising a backing layer, two adhesive layers, one of said adhesive layers disposed on one side of said backing layer and the second of said adhesive layers being disposed on the opposite side of said backing layer, said adhesive layers having similar adhesive properties and a release layer disposed on one of said adhesive layers, said release layer having a plurality of intermittently spaced apart slits disposed over its surface and inwardly of the longitudinal edges of said release layer, each of said slits defining a portion of the periphery of an intermittently spaced apart area to produce a plurality of intermittently spaced apart areas provided with a set and disposed over the surface of the release layer and inwardly of the longitudinal edges of said release layer, said areas having been deformed out of the plane of the release layer whereby said areas have a lesser degree of adhesion to the adhesive layer than the remainder of said layer and at least a portion of said areas remaining out of the plane of the release layer to provide easily grasped areas to facilitate removal of the release layer.
