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.
