Abstract

Abstract This invention relates to decorative plastics strips and motifs suitable for securing by high frequency welding to a base surface. The decorative strip comprises an extruded plastics strip consisting of a central tape-like web portion along each side of which is a bead portion which projects above the front face of the web portion, each bead portion having a thin and narrow welding flange projecting outwardly from the back edge thereof in the plane of the web portion. A strip of material providing a desired decorative finish is bonded to the front face of the web portion. The decorative motif is in the form of a panel made by securing across each of the ends of a length of the twin-beaded strip, a piece of an auxiliary plastics strip material comprising a bead portion having the shape of one of the bead portions of the twin-beaded strip. The bead portions of the strips have a metallised finish or appearance.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 63 words
A decorative motif as claimed in claim 1, wherein each end of the web portion of the twin-beaded strip projects slightly beyond the inner edges of the mitered bead portions and extends into a recess, of a height approximately corresponding to the thickness of the web portion, along the inwardly facing side of the bead portion of the associated piece of auxiliary strip.
Claim 2
Dependent Claim 33 words
A decorative motif as claimed in claim 1, wherein the inwardly projecting flanges of the pieces of auxiliary strip used in making the motif are formed with grooves in the upper surfaces thereof.
Claim 3
Dependent Claim 157 words
A decorative motif as claimed in claim 3, including a plurality of grooves along the rear of the web portion of the twin-beaded strip; a longitudinal groove along the rear of the twin-beaded strip directly behind each bead portion and extending thereinto; and strips of metallized transparent foil bonded along the surfaces of the bead portions of the twin-beaded and auxiliary strips; and wherein the strip of decorative material bonded to the front face of the web portion of the twin-beaded strip is of plastics material printed with a desired finish and covers substantially the entire width of the web portion; and wherein each end of the web portion of the twin-beaded strip projects slightly beyond the inner edges of the mitered bead portions and extends into a recess, of a height approximately corresponding to the thickness of the web portion, along the inwardly facing side of the bead portion of the associated piece of auxiliary strip.
Claim 4
Independent Claim 258 words
The method of making a decorative motif in the form of a panel, comprising the steps of fabricating a twin-beaded decorative plastics strip comprised of a central tape-like web portion along each side of which is a bead portion which projects above the front face of said web portion, each bead portion having a thin and narrow welding flange portion projecting outwardly from the back edge thereof in the plane of said web portion, said extruded plastics strip having bonded to the front face of said web portion a strip of material providing a desired decorative finish to said web portion, and each of said bead portions having a metallized appearance, fabricating a strip of auxiliary plastics material comprising a bead portion having the shape of one of said bead portions of the twin-beaded strip, said bead portion having a metallized appearance, and thin and narrow flanges projecting outwardly in opposite directions from both rear edges of the bead portion, cutting off a desired length of the twin-beaded strip, mitering the ends of thE bead portions thereof and cutting off the ends of the web portion between the mitered ends of the bead portions, cutting pieces of the auxiliary strip and mitering their ends so as to fit between the mitered ends of the bead portions of the twin-beaded strip, and then positioning the pieces of auxiliary strip across the ends of the twin-beaded strip with their inwardly facing flanges beneath the ends of the web portion and bonding said flanges to the back of the web portion.
Claim 5
Dependent Claim 88 words
The method as claimed in claim 5, wherein the twin-beaded and auxiliary strips are fabricated with grooves along the back of the web portion and the upper surface of the flange which is to project inwardly of the motif respectively, and the inwardly facing flanges of the pieces of auxiliary strip are welded to the back of the web portion of the twin-beaded strip under pressure to cause part of the softened plastics material to flow into the grooves as the flange is compressed during the welding operation.
