Benefits of technology

[0013] Another embodiment of the present invention may also be embodied in various masking materials used to define a boundary between a masked area of a surface and an unmasked area of the surface. Such masking materials comprise a substrate having a top surface, a bottom surface, at least one edge, an adhesive layer applied to at least a portion of the bottom surface of the substrate for adhering the masking material to the surface, and an absorbent edge layer that is applied to the at least one edge of the substrate. The absorbent edge layer at least substantially prevents liqui...

Problems solved by technology

A persistent problem with masking tapes of this type is that the tape is typically only partially successful in defining a clean masking edge or boundary between masked and unmasked surfaces.
In addition, the paper substrate has a tendency to absorb or wick moisture from the paint through the unprotected edge of the tape substrate.
This absorption causes swelling in the tape that degrades the ability of the tape to form a t...

Embodiment Construction

[0023] Although the disclosure hereof is detailed and exact to enable those skilled in the art to practice the invention, the physical embodiments herein disclosed merely exemplify the invention, which may be embodied in other specific structure. While the preferred embodiment has been described, the details may be changed without departing from the invention, which is defined by the claims.

[0024]FIG. 2 illustrates a cross section of a standard, prior art adhesive tape 10 of a type commonly used for masking. Tape 10 has a middle layer or substrate 12 and an adhesive layer 14 applied to a bottom surface of the substrate 12. In some instances, tape 10 may have a top layer 16 applied to a top surface of the substrate 12 that is impervious or at least resistant to liquids. Tape 10 is most often wound on a core 18 to form a roll 20 as illustrated in FIG. 1.

[0025] The present invention comprises an adhesive tape 30 as illustrated in FIGS. 3 and 4. Tape 30 has a substrate 32, an adhesive...

Abstract

An absorbent edge coating for masking tape and other masking materials is herein disclosed. A masking tape according to the present invention comprises a substrate having a top surface, a bottom surface, and at least one masking edge. The bottom surface of the substrate has an adhesive layer applied thereto. An absorbent edge coating is applied to at least one masking edge of the substrate so as to at least substantially prevent liquids addressed to the at least one coated masking edge from being absorbed into the substrate of the tape and from passing between the bottom surface of the tape and a surface to which the tape has been applied.

Description

RELATED APPLICATIONS [0001] This is a divisional application of U.S. patent application Ser. No. 10 / 138,683, filed May 3, 2002, titled “ADHESIVE TAPE FOR MASKING”, which is commonly assigned, the entire contents of which are incorporated herein by reference.FIELD OF THE INVENTION [0002] The present invention relates to an improved adhesive tape having an edge coating. [0003] More specifically, the present invention relates to an edge coating for masking tape and masking materials that improves the masking ability of those materials. BACKGROUND OF THE INVENTION [0004] Adhesive tapes for masking are typically comprised of a paper substrate having an adhesive layer applied to a bottom surface thereof. In addition, some masking tapes have an upper, liquid-resistant, or liquid-proof layer applied to an upper surface of the substrate. A persistent problem with masking tapes of this type is that the tape is typically only partially successful in defining a clean masking edge or boundary be...
