A method for use in making a sign, said method comprising:
- providing a laminated web comprised of a base layer of sheet material having first and second faces, a layer of plastic sign material in sheet form superimposed on said base layer and having a first face facing said base layer and a second face facing away from said base layer, a layer of permanently tacky adhesive between said base layer and said layer of plastic sign material, and a layer of activatable adhesive bonded to said second face of said layer of sign material and activatable into a tacky condition from an otherwise dry condition, said adhesive of said layer of permanently tacky adhesive and the materials constituting said base layer and said layer of plastic sign material being such that said adhesive of said layer of permanently tacky adhesive adheres more strongly to said second face of said base layer than to said first face of said layer of plastic sign material allowing said layer of plastic sign material to be peeled from said layer of permanently tacky adhesive with said permanently tacky adhesive in the course of such peeling remaining on said base layer and coming completely free of said layer of plastic sign material, said activatable adhesive in its tacky condition having a greater adhesion strength than said permanently tacky adhesive,
- maintaining said activatable adhesive in a dry condition,
- cutting a closed shape in said web by first cutting completely through said activatable adhesive while in a dry condition and then into said layer of sign material and finally no more than partially into said base layer to separate a shape portion of the layer of plastic sign material defining said closed shape from a waste portion of said layer of plastic sign material and to separate the portion of said layer of activatable adhesive associated with said shape portion of said layer of plastic sign material from that portion of said layer of activatable adhesive associated with said waste portion of said layer of plastic sign material,
- removing from said web said waste portion of said layer of plastic sign material and the portion of said layer of activatable adhesive associated with said waste portion to leave said shape portion of the layer of plastic sign material and the portion of said layer of activatable adhesive associated therewith on said base layer in free standing form,
- attaching said shape portion of said layer of plastic sign material to a supporting surface by activating the activatable adhesive associated therewith from a dry to a tacky condition and then placing said web against a supporting surface with the activated adhesive facing said supporting surface, said sub-steps of activating said activatable adhesive and of placing said web against a supporting surface being carried out in any sequence,
- pressing said shape portion of said layer of sign material toward said supporting surface by a force applied to said first face of said base layer in the area overlapping said shape portion of said layer of sign material such that the activated activatable adhesive causes said shape portion of said layer of sign material to adhere to said supporting surface, and
- then peeling said web from said supporting surface to remove said shape portion of said layer of sign material from the remainder of said web through the intermediary of the selected relative adhesion strengths between the layer of permanently tacky adhesive and the tackified activatable adhesive and to leave it attached to said supporting surface due to the adhesive effect of that portion of said layer of activatable adhesive associated with said shape portion of said layer of plastic sign material.
