Abstract
Official abstract text for this publication.
A gap finishing tape for use with drywall applications includes a trim strip body extending along a central body axis, a hot melt adhesive extending along the central body axis, and a backing paper. The trim strip body includes a first surface, a second surface opposite the first surface, a first side, and a second side opposite the first side, and is at least partially constructed from a metallic material. The backing paper is at least partially secured to the second surface of the trim strip body. The trim strip body is at least partially embedded in the hot melt adhesive.
First claim
Opening claim text (preview).
What is claimed is: 1. A gap-finishing tape for use in connection with drywall applications, the gap finishing tape comprising: a trim strip body extending along a central body axis, the trim strip body having a first surface and a second surface opposite the first surface, the trim strip body being constructed from a metallic material; a hot melt adhesive extending along the central body axis and having a first surface, a second surface opposite the first surface, a first side, and a second side opposite the first side; and a backing paper at least partially secured to the second surface of the hot-melt adhesive; wherein the trim strip body is at least partially embedded into the first surface of the hot melt adhesive such that the entire first surface of the trim strip body is exposed and free of hot melt adhesive such that at least a portion of the first surface of the trim strip body is configured to contact a surface of a drywall panel. 2. The gap-finishing tape of claim 1 , wherein the trim strip body has a first width and the hot melt adhesive has a second width, wherein the first width is less than the second width such that the hot melt adhesive extends beyond the width of the trim strip body. 3. The gap-finishing tape of claim 1 , wherein the trim strip body has a first thickness and the hot melt adhesive has a second thickness, wherein the first thickness is less than the second thickness. 4. The gap-finishing tape of claim 1 , wherein the backing paper is at least partially secured to the second surface of the hot melt adhesive via lamination. 5. The gap-finishing tape of claim 1 , wherein the hot melt adhesive is laminated onto the trim strip body. 6. The gap-finishing tape of claim 1 , wherein the backing paper is constructed from at least one of a nonwoven paper, a fiberglass mesh, or a polymer film. 7. The gap-finishing tape of claim 1 , wherein the hot melt adhesive is dimensioned such that a first thickness between the first surface and the second surface at the central body axis is greater than a second thickness between the first surface and the second surface at the first side and the second side. 8. The gap-finishing tape of claim 1 , wherein the hot melt adhesive has a trapezoidal cross-section. 9. The gap-finishing tape of claim 1 , wherein the hot melt adhesive has a thickness between approximately 0.005″ and approximately 0.025″. 10. The gap-finishing tape of claim 1 , wherein the trim strip body has a thickness between approximately 0.003″ and approximately 0.020″. 11. The gap-finishing tape of claim 1 , wherein a portion of the backing paper is secured to the second surface of the hot melt adhesive without an intervening layer of adhesive material.
