Abstract:
An adhesive transfer device for performing an adhesive transfer operation on a selected substrate, said device comprising:one or more adhesive transfer sheets, each of said adhesive transfer sheets comprising: a generally flat base substrate providing an adhesive carrying surface, a layer of pressure-sensitive adhesive adhered to the adhesive carrying surface of said base substrate, a generally flat release liner substrate providing a release surface, said release liner substrate being disposed in covering relation over said adhesive layer with said release surface adhering to the adhesive layer opposite said base substrate, the relative strengths of the adhesive bonding between said adhesive carrying surface and said adhesive layer and said release surface and said adhesive layer being such that the adhesive transfer operation can be initiated by moving said release liner substrate and said base substrate relatively away from one another with said adhesive layer remaining adhered to the adhesive carrying surface of said base substrate and then engaging the selected substrate with a portion of said adhesive layer so as to adhere said selected substrate to said adhesive layer portion, the strength of the adhesive bonding between said adhesive layer and said adhesive carrying surface being such that, after the selected substrate has been engaged with and adhered to said portion of said adhesive layer, the adhesive transfer operation can be completed by moving the selected substrate and the base substrate relatively away from one another with the aforesaid portion of the adhesive layer remaining adhered to said selected substrate, thereby allowing the selected substrate to be adhered to a desired surface by engaging the portion of the adhesive layer thereon with the desired surface.
