Abstract

Abstract A three-dimensional sign character is formed with improved circumscribing opaque metal sheet strip siding. The sign, typically having an interior light source, includes a translucent plastic face circumscribed by opaque sheet metal strip siding. The sheet metal strip siding includes a plastic strip bonded directly by gluing to a freshly abraded band on the sheet metal strip. Convolute folds are formed on either side of the sheet metal strip. One convolute fold is formed adjacent an edge of the plastic strip so as to extend angularly above and abut the plastic stripping to function as a light stop. The secured plastic strip serves as the bonding point to the translucent face of the sign. The sheet metal strip siding is particularly adaptable to continuous formation on a specialized rolling mill including the steps of preheating the strip, abrading a band on the strip, gluing over the abraded band, placing a plastic strip over the glue covered abraded band, working opposite edges of the strip with a rolling mill to produce convolute folds, registering the plastic strip to the convolute folds, and heating the strip to cure and bond the registered plastic strip to the abraded band on the sheet metal strip.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 199 words
An opaque sheet strip for circumscribing the periphery of a sign character having a plastic face, said sheet strip comprising: an elongate sheet metal strip having first and second side edges, at least one of said edges of said metal strip having a convolute fold wherein a first longitudinal area immediately adjacent said convoluted edge is folded back to contact a second longitudinal area immediately adjacent said first longitudinal area; an abraded band on said sheet metal strip adjacent said convolute fold; a plastic strip overlying said abraded band, said plastic strip having a width substantially greater than the thickness of said plastic face, said plastic strip extending a distance in the plane of said metal strip substantially greater than the thickness of said plastic face, and said plastic strip being suitable for bonding to said plastic face; and a layer of adhesive between said plastic strip and said abraded band for bonding said plastic strip to said abraded band adjacent said convoluted edge, the edge of said plastic strip adjacent said convoluted edge of said metal strip registered with respect to said metal strip to abut said convolute fold but not be mechanically gripped by said convolute fold.
Claim 2
Dependent Claim 199 words
An opaque sheet strip for circumscribing the periphery of a sign character having a plastic face, said sheet strip comprising: an elongate sheet metal strip having first and second side edges, at least one of said edges of said metal strip having a convolute fold wherein a first longitudinal area immediately adjacent said convoluted edge is folded back to contact a second longitudinal area immediately adjacent said first longitudinal area; an abraded band on said sheet metal strip adjacent said convolute fold; a plastic strip overlying said abraded band, said plastic strip having a width substantially greater than the thickness of said plastic face, said plastic strip extending a distance in the plane of said metal strip substantially greater than the thickness of said plastic face, and said plastic strip being suitable for bonding to said plastic face; and a layer of adhesive between said plastic strip and said abraded band for bonding said plastic strip to said abraded band adjacent said convoluted edge, the edge of said plastic strip adjacent said convoluted edge of said metal strip registered with respect to said metal strip to abut said convolute fold but not be mechanically gripped by said convolute fold.
Claim 3
Dependent Claim 43 words
The opaque strip of claim 1 and wherein said convoluted edge of said metal strip, which edge abuts but does not mechanically grip said plastic strip, extends angularly beyond that surface of said plastic strip which is remote from said layer of adhesive.
Claim 4
Dependent Claim 56 words
The opaque strip of claim 2 and including a first convolute extending angularly beyond that surface of said plastic strip which is remote from said layer of adhesive and a second convolute at a distance removed from said first convolute, said edge of said metal strip between said first and second convolute defining an obtuse angle.
Claim 5
Dependent Claim 15 words
The opaque strip of claim 1 and wherein both said edges have a convolute fold.
Claim 6
Dependent Claim 21 words
The opaque strip of claim 1 and wherein a closed cell urethane strip is secured along the other of said edges.
