Abstract
Abstract A manually operated guide forms a sheet of heated pliable laminate about an adhesively coated 180° rounded edge of a substrate, such as may be found on the front edge of a countertop. The guide is pivotally attached to a support member at an initial angle to guide the laminate along the major portion of the rounded edge and at a different angle to guide the laminate along the remaining portion to assure continuing progressive contact between the laminate and the rounded edge.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
77 words
A method for laminating a laminate about a 180° rounded edge of a substrate, said method comprising the steps of: (a) pivoting a guide in one direction about a first pivot axis to progressively and continuously form the laminate about a first portion of the rounded edge; and (b) further pivoting the guide in the same direction about a second pivot axis to progressively and continuously form the laminate about a second portion of the rounded edge.
Claim 2
Independent Claim
77 words
A method for laminating a laminate about a 180° rounded edge of a substrate, said method comprising the steps of: (a) pivoting a guide in one direction about a first pivot axis to progressively and continuously form the laminate about a first portion of the rounded edge; and (b) further pivoting the guide in the same direction about a second pivot axis to progressively and continuously form the laminate about a second portion of the rounded edge.
Claim 3
Dependent Claim
52 words
The method as set forth in claim 1 wherein the guide is pivotally attached to a pivotally mounted support member and including the step of locking the guide to the support member during said pivoting step and the step of unlocking the guide from the support member during said further pivoting step.
Claim 4
Independent Claim
192 words
A method for attaching a laminate to the top and bottom sides of a substrate and about a 180° rounded edge of the substrate joining the top and bottom sides, said method comprising the steps of: (a) forcing the laminate against the top side of the substrate by pivoting in one direction a pivotally mounted member bearing against the laminate; (b) guiding the laminate adjacent the substrate from the top side of the substrate to the apex of the rounded edge of the substrate with a spine extending from the pivotally mounted member; (c) maintaining the laminate against the apex of the rounded edge on completion of the pivotal movement of the pivotally mounted member; (d) further guiding the laminate adjacent the substrate from the apex of the rounded edge of the substrate to the bottom side of the substrate by pivoting in the same direction a guide pivotally secured to the pivotally mounted member; and (e) further forcing the laminate against the bottom side of the substrate on completion of the pivotal movement of the guide while the laminate is retained adjacent the apex of the rounded edge by the spine.
Claim 5
Independent Claim
192 words
A method for attaching a laminate to the top and bottom sides of a substrate and about a 180° rounded edge of the substrate joining the top and bottom sides, said method comprising the steps of: (a) forcing the laminate against the top side of the substrate by pivoting in one direction a pivotally mounted member bearing against the laminate; (b) guiding the laminate adjacent the substrate from the top side of the substrate to the apex of the rounded edge of the substrate with a spine extending from the pivotally mounted member; (c) maintaining the laminate against the apex of the rounded edge on completion of the pivotal movement of the pivotally mounted member; (d) further guiding the laminate adjacent the substrate from the apex of the rounded edge of the substrate to the bottom side of the substrate by pivoting in the same direction a guide pivotally secured to the pivotally mounted member; and (e) further forcing the laminate against the bottom side of the substrate on completion of the pivotal movement of the guide while the laminate is retained adjacent the apex of the rounded edge by the spine.
