Abstract
Apparatus, systems and methods for making a fibrous products form molten material into fibers. The fibers are sprayed with a coolant liquid to cool the fibers. A flow rate of the sprayed coolant liquid is controllable. The fibers are also sprayed with a binder dispersion. The fibers are directed toward a conveyor to form an uncured fibrous pack. A thickness of the uncured pack is measured and the flow rate of the sprayed coolant liquid is controlled based on the measured thickness of the uncured pack.
Claims12
A method of making a fibrous product comprising:
- forming molten material into fibers;
- spraying the fibers with a coolant liquid to cool the fibers, wherein a flow rate of the sprayed coolant liquid is controllable;
- spraying the cooled fibers with a binder dispersion at a constant flow rate by spraying the cooled fibers with a plurality of binder spray rings, wherein two or more of the binder spray rings spray binder dispersion at different flow rates;
- directing the fibers toward a conveyor to form an uncured fibrous pack;
- measuring a thickness of the uncured pack;
- controlling the flow rate of the sprayed coolant liquid based on the measured thickness of the uncured pack, while maintaining the spraying of the cooled fibers with the binder dispersion at a constant flow rate.
