Abstract: A marker system for pipes or valves comprises a tape having a surface layer and a pressure sensitive adhesive layer, the tape defining spaced-apart transparent window areas. A release paper backing is deployed on the adhesive layer of the tape, and the release paper backing includes pre-cut window backing portions generally registered with the transparent window areas of the tape. The pre-cut window backing portions may be joined with the release paper backing along a hinge/tear line whereby the window backing portions may be folded away from the tape. The marker system further comprises information cards sized to be adhered in the transparent window areas of the tape. The marker system is installed by first removing or folding back the pre-cut window backing portions of the release paper backing and adhering the information cards in the window area.

Abstract: Color-filled debossed indicia are provided on metal substrates. Colored tape comprising a layer of resinous film and a layer of thermoset adhesive wherein the film may be colored, the adhesive may be colored, or an additional layer of acrylic paint may be provided between the film and the adhesive, is interposed between indicia dies and the metal substrate during debossing. A portion of tape corresponding to the indicia is sheared away and deposited on the surface of the indicia. The conversion of kinetic energy to heat during the debossing operation is sufficient in some applications to permanently bond the tape to the metal substrate by means of the thermoset adhesive. If necessary, the tape may be heat treated and cooled to permanently bond the tape to the metal substrate.
