Claims
- 1. An apparatus for forming a fiberglass mat comprising,
- means for directing chopped fiberglass strands in a moisturized air inducing means and then into the inlet and out of the exit of a blower means,
- means within the blower means to partially open the chopped fiberglass strands into fiberglass partially opened strands, as well as means to direct the partially opened strands into a duct means,
- the duct means being constructed to maintain a minimum uniform air velocity within the duct means for a given blower means exit velocity,
- a foraminous conveyor means adjacent the duct means for the deposit of the partially opened strands in the form of a glass mat, and
- means located adjacent to the foraminous conveyor means to exert a vacuum force through the conveyor to hold the partially opened strands of the glass mat on the conveyor.
- 2. The apparatus of claim 1 wherein the air velocity exiting the blower means is less then 4400 fpm and the duct means has a taper from its blower side to its conveyor side of 1 to 18 degrees measured from a center line drawn from a center position of its inlet to a center position on its exit side.
- 3. The apparatus of claim 1 wherein the moisturized air inducing means provides a relative humidity of approximately 70%.
