Patent number: 11951712Abstract: A glass facer for a constructions board includes a first non-woven layer of coarse fibers and a second non-woven layer of coarse fibers and microfibers. The glass facer also includes a binder that simultaneously binds or adheres the coarse fibers of the first non-woven layer together, the coarse fibers and the microfibers of the second non-woven layer together, and the first non-woven layer to the second non-woven layer. The first non-woven layer has a porosity and air permeability that enables the first non-woven layer to absorb a material of the construction board when the glass facer is positioned atop the construction board during manufacture of the construction board. The second non-woven layer is configured to block the material of the construction board from passing through the glass facer to an exterior surface of the second non-woven layer so that the material is not externally visible.Type: GrantFiled: January 14, 2020Date of Patent: April 9, 2024Assignee: Johns ManvilleInventors: Souvik Nandi, Glenda B Bennett, Thomas Matthews

Patent number: 10618248Abstract: 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.Type: GrantFiled: June 19, 2017Date of Patent: April 14, 2020Assignee: Johns ManvilleInventors: Souvik Nandi, Glenda B Bennett, Thomas Matthews

Patent number: 7462259Abstract: New coated nonwoven fibrous mats having properties particularly suited for a facer on gypsum wallboard and other substrates and in laminates of various types, and the method of making the coated mat is disclosed. The mat preferably contains a major portion of glass fibers and a minor portion of a resinous binder. The coating is preferably permeable and reduces fiber dust and abrasion experienced in the past with relatively coarse, relatively inexpensive glass fibers in the mat. Contrary to previous coating methods, the coated fibrous mat is made in-line on a wet mat forming production line by applying a wet foam binder onto a wet, fibrous web followed by drying and curing in-line.Type: GrantFiled: October 14, 2004Date of Patent: December 9, 2008Assignee: Johns MnavilleInventors: Richard Emil Kajander, Alan Michael Jaffee, Glenda B. Bennett
