Abstract

This invention relates to a novel thermoplastic profile roofing strip and an apparatus for welding the thermoplastic profile roofing strip to a thermoplastic roofing membrane.

Claims (30)

1. A thermoplastic profile roofing strip, comprising

a horizontal base extending longitudinally, the base comprising:

a planar base portion defining a first plane;

a first substantially planar upward bend along one longitudinal edge; and

a second substantially planar upward bend along a second longitudinal edge opposite the first edge, the first bend and the second bend being substantially equal, and wherein the first bend and the second bend are operable to bend downwards toward the first plane;

a vertical central portion laterally connected to an upper surface of the planar base portion and having a hook along an upper longitudinal edge of the vertical central portion;

wherein the first and second substantially planar upward bends are substantially entirely planar without a curvature defined therein;

wherein the vertical central portion extends longitudinally along the planar base portion; and

wherein the hook of the vertical central portion extends partially horizontal from the upper longitudinal edge and partially downward therefrom;

wherein the horizontal base further comprises an adhesive longitudinally along its bottom surface.

2. The thermoplastic profile roofing strip of claim 1 , wherein the horizontal base ranges from about ½ inch to about 3 inches wide.

3. The thermoplastic profile roofing strip of claim 1 , wherein the first bend and second bend range from about ⅛ to about 1 inch wide.

4. The thermoplastic profile roofing strip of claim 1 , wherein the first bend and second bend have an angle ranging from about 15 to about 60 degrees from the horizontal base.

5. The thermoplastic profile roofing strip of claim 1 , wherein hook further comprises a lip.

6. The thermoplastic profile strip of claim 1 , wherein the strip comprises primarily thermoplastic olefin.

7. A thermoplastic profile roofing strip, comprising

a horizontal base extending longitudinally, the base comprising:

a planar base portion defining a first plane;

a first upward bend along one longitudinal edge; and

a second upward bend along a second longitudinal edge opposite the first edge, the first bend and the second bend being substantially equal, and wherein the first bend and the second bend are operable to bend downwards toward the first plane;

a vertical central portion laterally connected to an upper surface of the planar base portion and having a hook along an upper longitudinal edge of the vertical central portion;

wherein the first and second upward bends substantially do not comprise a curvature;

wherein the vertical central portion extends longitudinally along the planar base portion; and

wherein the hook of the vertical central portion extends partially horizontal from the upper longitudinal edge and partially downward therefrom;

wherein the horizontal base further comprises an adhesive longitudinally along its bottom surface.

8. The thermoplastic profile roofing strip of claim 7 , wherein the horizontal base ranges from about ½ inch to about 3 inches wide.

9. The thermoplastic profile roofing strip of claim 7 , wherein the first bend and second bend range from about ⅛ to about 1 inch wide.

10. The thermoplastic profile roofing strip of claim 7 , wherein the first bend and second bend have an angle raging from about 15 to about 60 degrees from the horizontal base.

11. The thermoplastic profile roofing strip of claim 7 , wherein hook further comprises a lip.

12. The thermoplastic profile strip of claim 7 , wherein the strip comprises primarily thermoplastic olefin.
