Abstract

A shake mechanism is provided for shaking a breast roll at the wet end of a conventional glass mat machine. A method of producing a glass fiber mat is provided, the method involving combining glass fibers with a dispersant medium to form an aqueous slurry, and shaking the aqueous slurry to redistribute fibers from areas of high concentration to areas of lower concentration. A glass fiber mat production line is also provided, the production line comprising a slurry formation station for combining glass fibers with a dispersant medium to form an aqueous slurry, and a hydroformer for shaking the slurry to redistribute glass fibers from areas of high concentration to areas of lower concentration.

Claims (24)

1. A method of producing a glass fiber mat, the method comprising:

combining glass fibers with a dispersant medium to form an aqueous slurry; and

shaking the aqueous slurry to redistribute fibers from areas of high concentration to areas of lower concentration;

forming a fabric after shaking the slurry and applying it on a moving wire; and

shaking the fabric for a second time.

2. The method of producing a glass fiber mat of claim 1 , further comprising:

applying a binder to the fabric.

3. The method of producing a glass fiber mat of claim 2 , further comprising:

removing excess binder from the fabric.

4. The method of producing a glass fiber mat of claim 3 , further comprising:

drying and curing the fabric to form a reinforced glass fiber mat.

5. The method of producing a glass fiber mat of claim 4 , further comprising:

coating the mat with hot asphalt to form a shingle.

6. A glass fiber mat production line comprising:

a slurry formation station for combining glass fibers with a dispersant medium to form an aqueous slurry;

a hydroformer for shaking the slurry to redistribute glass fibers from areas of high concentration to areas of lower concentration;

wherein the slurry is landed onto a moving wire around the breast roll to form a fabric; and

a second shake mechanism for shaking the fabric after exiting the drainage section.

7. The glass fiber mat production line of claim 6 , further comprising:

a binder saturation station for applying a binder to the fabric and removing excess binder solution and water from the fabric.

8. The glass fiber mat production line of claim 7 , further comprising:

an oven drying and curing station for drying the fabric in an oven.

9. The glass fiber mat production line of claim 8 , further comprising:

a gauging and fabrication station for coating the fabric with an asphalt to form shingles.
