Abstract

Shingle blanks including a first fold region, a second fold region, a third region, a lower edge and an upper edge are provided. The shingle blank has a length. The first and second fold regions extend substantially across the length of the shingle blank. The second fold region is positioned between the first and third fold regions. A first perforation line is positioned between the second and third fold regions. A second perforation line is positioned between the first and second fold regions. A reinforcement material is positioned over the first perforation line and configured to reinforce the first perforation line. The reinforcement material includes apertures configured to allow an asphalt coating to bleed through the reinforcement material. The first and second perforation lines facilitate folding of the first and second fold regions on top of the third region to form a three layered stack.

First claim

What is claimed is:

1. A method of manufacturing asphalt-based shingle blanks, comprising the steps of:
coating a substrate with an asphalt coating to form an asphalt coated sheet, the substrate comprising a lower edge and an upper ledge, a height defined between the lower edge and upper edge and a length;
applying a reinforcement material to a portion of an upper surface of the asphalt coated sheet, wherein the reinforcement material includes a plurality of apertures, wherein the asphalt coating of the substrate bleeds through the plurality of apertures of the reinforcement material to form a reinforcement region on a portion of the upper surface of the asphalt coated sheet;
applying a surface layer of granules to the upper surface of the asphalt coated sheet including the reinforcement region;
forming a first perforation line in the substrate along the length of the substrate, wherein the reinforcement material is positioned to cover the first perforation line;
forming a second perforation line in the substrate along the length of the substrate;
wherein a first fold region is formed between the second perforation line and the upper edge of the substrate, wherein a second fold region is formed between the first perforation line and the second perforation line, and wherein a third region is formed between the first perforation line and the lower edge.

2. The method of claim 1 , further comprising the step of applying a release tape to a portion of a lower surface of the asphalt coated sheet, wherein the release tape is positioned to cover the second perforation line.

3. The method of claim 1 , further comprising the step of forming at least one additional perforation line in the substrate that extends substantially across the height of the substrate.

4. The method of claim 1 , further comprising the step of cutting the substrate into a plurality of discrete shingle blanks, wherein each shingle blank comprises a lower edge, an upper edge, a first perforation line, a second perforation line, a first fold region formed between the second perforation line and the upper edge of the shingle blank, a second fold region formed between the first perforation line and the second perforation line of the shingle blank, and third region formed between the first perforation line and the lower edge of the shingle blank.

5. The method of claim 2 , further comprising the step of cutting the substrate into a plurality of discrete shingle blanks, wherein each shingle blank comprises a lower edge, an upper edge, a first perforation line, a second perforation line, a first fold region formed between the second perforation line and the upper edge of the shingle blank, a second fold region formed between the first perforation line and the second perforation line of the shingle blank, and third region formed between the first perforation line and the lower edge of the shingle blank.

6. The method of claim 3 , further comprising the step of cutting the substrate into a plurality of discrete shingle blanks, wherein each shingle blank comprises a lower edge, an upper edge, a height defined between the lower edge and upper edge, a length, a first perforation line and a second perforation line that extend substantially across the length of the shingle blank, and two additional perforation lines that extend substantially across the height of the shingle blank, a first fold region formed between the second perforation line and the upper edge of the shingle blank, a second fold region formed between the first perforation line and the second perforation line of the shingle blank, and a third region formed between the first perforation line and the lower edge of the shingle blank.

7. The method of claim 1 , wherein the substrate is a continuous sheet payed out from a roll.

8. The method of claim 1 , wherein the substrate is coated with the asphalt by contacting the substrate with a roller which is in contact with a supply of asphalt.

9. The method of claim 1 , wherein the asphalt coating comprises a filler material.

10. A method of manufacturing asphalt-based shingle blanks, comprising the steps of:
coating a continuous sheet of substrate with an asphalt coating to form an asphalt coated sheet, the substrate comprising a lower edge and an upper ledge, a height defined between the lower edge and upper edge and a length;
applying a strip of reinforcement material to a portion of an upper surface of the asphalt coated sheet;
applying a surface layer of granules to the upper surface of the asphalt coated sheet;
forming a first perforation line in the substrate along the length of the substrate, wherein the reinforcement material is positioned to cover the first perforation line;
forming a second perforation line in the substrate along the length of the substrate;
wherein a first fold region is formed between the second perforation line and the upper edge of the substrate, wherein a second fold region is formed between the first perforation line and the second perforation line, and wherein a third region is formed between the first perforation line and the lower edge.

11. The method of claim 10 , further comprising the step of applying a release tape to a portion of a lower surface of the asphalt coated sheet, wherein the release tape is positioned to cover the second perforation line.

12. The method of claim 10 , further comprising the step of forming at least one additional perforation line in the substrate that extends substantially across the height of the substrate.

13. The method of claim 10 , further comprising the step of cutting the substrate into a plurality of discrete shingle blanks, wherein each shingle blank comprises a lower edge, an upper edge, a first perforation line, a second perforation line, a first fold region formed between the second perforation line and the upper edge of the shingle blank, a second fold region formed between the first perforation line and the second perforation line of the shingle blank, and third region formed between the first perforation line and the lower edge of the shingle blank.

14. The method of claim 11 , further comprising the step of cutting the substrate into a plurality of discrete shingle blanks, wherein each shingle blank comprises a lower edge, an upper edge, a first perforation line, a second perforation line, a first fold region formed between the second perforation line and the upper edge of the shingle blank, a second fold region formed between the first perforation line and the second perforation line of the shingle blank, and third region formed between the first perforation line and the lower edge of the shingle blank.

15. The method of claim 12 , further comprising the step of cutting the substrate into a plurality of discrete shingle blanks, wherein each shingle blank comprises a lower edge, an upper edge, a height defined between the lower edge and upper edge, a length, a first perforation line and a second perforation line that extend substantially across the length of the shingle blank, and two additional perforation lines that extend substantially across the height of the shingle blank, a first fold region formed between the second perforation line and the upper edge of the shingle blank, a second fold region formed between the first perforation line and the second perforation line of the shingle blank, and a third region formed between the first perforation line and the lower edge of the shingle blank.

16. The method of claim 10 , wherein the substrate is coated with the asphalt by contacting the substrate with a roller which is in contact with a supply of asphalt.
