ABSTRACT:
A method and apparatus for expanding the fiber column produced by a rotary fiber glass manufacturing unit. A rotating bell-shaped shell is mounted beneath the rotary disc of the manufacturing unit so that the lower portion of the shell is in the path of the fiber column, causing the column to be outwardly deflected. Water is directed on the inner surface of the shell to cool the shell in order to prevent curing of binder which comes in contact with the shell, and binder is applied below the point of water application. If an amount of water in excess of the amount needed to cool the shell is provided it is thrown outward in the form of a spray which wets the fibers. The water spray also prevents fiber and binder from accumulating on the bottom edge of the shell.
