ABSTRACT:
This invention provides a process and apparatus which automatically and in a continuous and uninterrupted manner laminates a narrow strip of bituminous coated glass mat to the bottom side of a coated glass mat, cuts the laminated product to produce a laminate having cut-out areas between remaining tabs and then adheres thin strips of coated glass mat across the tabs to underlie the tabs and the cut-out areas. The final shingle is made from a single glass mat which is processed into a three level shingle, each level being made of a portion of the original glass mat.
