Abstract

A system for forming a facer includes a hydroformer that receives a first fluid and a second fluid. A first fluid line is configured to deliver the first fluid to a first inlet pipe and a second fluid line configured to deliver the second fluid to a second inlet pipe. The first fluid line includes a first fiber source that stores a first type of fibers and a first thick stock pump that pumps the first type of fibers to the first inlet pipe. The second fluid line includes a second fiber source that stores a second type of fibers and a second thick stock pump that pumps the second fluid to the second inlet pipe. The first fluid and second fluid are simultaneously poured or delivered onto a porous belt or surface to form the facer.
