A roll coater for placing binder on the fibers prior to being wound around a rotating drawing drum. The drawing drum draws fibers out of orifices in the bottom of a slowly reciprocating furnace. The fibers form a mat on the drawing drum that is later removed and expanded. The roll coater includes a graphite or other material coating drum that rotates in a bath of liquid binder and/or wetting agents, and reciprocates with the furnace. The fibers scrape over the surface of the coating drum after being formed but before winding around the drawing drum. The binder and/or wetting agent picked up on the surface of the coating drum coats the fibers with binder and/or wetting agent. Liquid binder and/or wetting agent is replenished in the bath in which the coating drum is partially submerged by a float, sensor, pump and large container of binder/wetting agent.
An improved apparatus for forming a fiberglass mat, the apparatus including a glass-containing furnace that reciprocates along a reciprocation path near a drawing drum mounted to rotate around a drawing drum axis that is aligned substantially parallel to the path of furnace reciprocation, for drawing glass fibers along a fiber path extending from furnace orifices to the drawing drum, thereby winding the glass fibers around the drawing drum to form a mat, wherein the improvement comprises:
