Abstract
There is provided a system and method for manufacturing continuous strand fiberglass of progressive density with varying skins. Glass media is melted into molten glass within a temperature controlled melter, the molten glass exits the melter through orifices of a bushing plate, which is oriented 6 degrees relative to the axis of a rotating drum. A rotating drum receives the molten glass exiting the bushing plate, and resin and water are applied. The fiberglass media is fed through rollers before it enters a curing oven.
Claims20
A method of manufacturing fiberglass media comprising:
- providing glass into a melter and through a bushing plate to produce continuous glass filament strands;
- repeatedly traversing the melter above a rotating drum in a first direction along a substantial length of the rotating drum and an opposite second direction along the substantial length of the rotating drum;
- depositing the continuous glass filament strands onto the rotating drum;
- spraying resin onto the continuous glass filament strands on the rotating drum to form a fiberglass mat;
- removing the fiberglass mat from the rotating drum;
- providing the fiberglass mat through a roller apparatus comprising an upper roller and a lower roller;
- applying a liquid consisting of water to the fiberglass mat;
- and
- immediately after applying the liquid to the fiberglass mat, curing the fiberglass mat in a curing oven.
