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.
Claims9
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.
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.
