Abstract
The invention relates to a method and an apparatus for forming and applying edging material to the corners of ductwork and other conduit structures.
Claims5
A method for covering corner edges of ductwork and other conduit structures comprising:
- cutting a strip of corner edging material, that has at least one adhesive surface and at least one score line on the adhesive surface side extending linearly and parallel to the edges of the strip, to the length required to cover the corner edge;
- bending the strip at the score line to create two regions of the strip;
- securing the adhesive surface of one region of the strip to one surface of the corner edge being covered;
- and
- securing the adhesive surface of the other region of the strip to the remaining portion of the corner edge being covered forming a straight corner edge wherein the strip is from 0.005 inches thick to 0.0625 inches thick and formed of material from the group consisting of rigid, high impact grade polyvinyl chloride, light gauge metal and composite of aluminum fused to rigid polyvinyl chloride and the strip is flat when applied to the ductwork or conduit structure.

A method for covering the terminal end of insulated pipes comprising:
- cutting a strip of corner edging material, that has one adhesive surface and at least one score line on the adhesive surface side extending linearly and parallel to the edges of the strip, to the length required to cover the insulated pipe;
- bending the strip at a score line to provide a region having a width that extends from the outside of the insulated pipe to be covered to the outer edge of insulation covering the insulated pipe;
- securing the other region of the strip to the insulation covering the insulated pipe;
- cutting the region of the strip having the width that extends from the outside of the insulated pipe to the outer edge of the insulation into discrete segments;
- and
- securing the discrete segments to the terminal end of the insulation wherein the strip is from 0.005 inches thick to 0.0625 inches thick and formed of material from the group consisting of rigid, high impact grade polyvinyl chloride, light gauge metal and composite of aluminum fused to rigid polyvinyl chloride and the strip is flat when applied to the insulated pipe.
