Patent number: 9062415Abstract: Systems and methods for forming fiber webs, including those suitable for use as filter media and battery separators, are provided. In some embodiments, the systems and methods involve designs which allow improved control of the fiber web forming process. For example, in certain embodiments involving the flowing of more than one fiber mixtures, the amount of mixing of the fiber mixtures may be controlled to produce fiber webs having different structural and/or performance characteristics. In some embodiments, the systems and methods can be used to form fiber webs having a gradient in a property across a portion of, or the entire, thickness of the fiber web.Type: GrantFiled: May 7, 2014Date of Patent: June 23, 2015Assignee: Hollingsworth & Vose CompanyInventors: Milind Godsay, Mark S. Millar

Patent number: 8877011Abstract: Systems and methods for forming fiber webs, including those suitable for use as filter media and battery separators, are provided. In some embodiments, the systems and methods may involve the use of one or more fiber mixtures to form a fiber web. The fiber mixtures may flow in different portions of a system for forming a fiber web that may be separated by a lamella, and may join at a fiber web forming zone to produce a fiber web having multiple layers. The amount of mixing of the fiber mixtures at or near the fiber web forming zone may be controlled to produce fiber webs having different structural and/or performance characteristics. In some embodiments, the systems and methods described herein can be used to form fiber webs having a gradient in a property across a portion of, or the entire, thickness of the fiber web.Type: GrantFiled: May 11, 2012Date of Patent: November 4, 2014Assignee: Hollingsworth & Vose CompanyInventors: Douglas M. Guimond, Mark S. Millar, David Vallery, Milind Godsay
