Apparatus and method for controlling moisture in the manufacture of glass fiber insulation

A manufacturing system for making a fibrous product, the system comprising:

• a plurality of fiberizing arrangements associated with a conveyor movable in a machine direction, each fiberizing arrangement comprising:
• a fiberizer configured to form fibers from a source of molten material;
• a plurality of coolant fluid dispensers configured to atomize a coolant fluid and spray the fibers with the atomized coolant to cool the fibers;
• a control processor programmed to adjust flow to at least one of said coolant fluid dispensers to provide atomized coolant fluid droplets that are a different size than atomized coolant fluid droplets provided by at least one other coolant fluid dispenser.

A manufacturing system for making a fibrous product, the system comprising:

• a plurality of fiberizing arrangements associated with a conveyor movable in a machine direction, each fiberizing arrangement comprising:
• a fiberizer configured to form fibers from a source of molten material;
• a first coolant fluid dispensing ring;
• a control processor programmed to adjust flow to the first coolant fluid dispensing ring to atomize coolant fluid to form coolant fluid droplets that are a first size and spray the fibers with the atomized coolant fluid droplets having the first size to cool the fibers;
• a second coolant fluid dispensing ring;
• wherein the control processor is programmed to adjust flow to the second coolant fluid dispensing ring to atomize coolant fluid to form coolant fluid droplets that are a second size and spray the fibers with the atomized coolant fluid droplets having the second size to cool the fibers, wherein said first size is different than said second size;
• a binder dispenser configured to spray the cooled fibers with a binder dispersion.
