  • Patent number: 4578136
    Abstract: Each disclosed wire marker or other adhesive product includes a pressure-sensitive adhesive portion or applique that has a readily peelable bond to the release surface of a carrier sheet. A tab extends from an extremity of the applique, to be torn away when the applique is adhered to a receiving surface, due to a weakening formation between the tab and the applique. Wire markers have an elongated wire-marking portions divided into segments by connections that are progressively weaker in the order of their distance from the tab. Where made by screen printing, the same operation that defines the outlines of the adhesive products also produces the weakening formations.

  • Patent number: 4391853
    Abstract: The disclosed adhesive products include a carrier sheet bearing a polymeric film and an adhesive layer, overlying the film as in dry transfers or underlying the film in products such as wire markers and other labels, or there may be adhesive layers both over and underneath the polymeric film. A constituent initially contained in the polymeric film layer migrates into an ordinarily non-tacky precursor of the adhesive layer, thereby rendering the precursor tacky. The precursor layer becomes adhesive only where it is opposite the polymeric film, being non-tacky outside the area of the film. In important applications, the common area of film and adhesive layers does not cover the whole carrier sheet. Both the adhesive precursor layer and the polymeric film may include portions extending outside the common area.
