Patent number: 7856853Abstract: A method of manufacturing mineral fibers includes rotating an orificed spinner and supplying molten mineral material to the spinner to centrifuge streams of molten mineral material. A downward annular flow of attenuating gases is directed to attenuate the streams of molten mineral material into mineral fibers. A mixture of combustion air and combustion gas is supplied to an annular burner positioned around the spinner. Heat from the annular burner is directed toward the spinner and the streams of molten mineral material to heat the spinner and assist in attenuating the streams of molten mineral material into mineral fibers. A pressure sensor senses the pressure of the combustion air prior to the introduction of the combustion air to the burner. The pressure of the combustion air is controlled in response to the sensed pressure to maintain the pressure of the combustion air at a specific pressure.Type: GrantFiled: February 1, 2006Date of Patent: December 28, 2010Assignee: Owens Corning Intellectual Capital, LLCInventors: Michael E. Evans, Patrick M. Gavin, Paul S. Dangler, Michael T. Pellegrin, Harold J. Holler

Patent number: 6189344Abstract: A method and device is disclosed for distributing a veil by applying low frequency sound to at least one portion of the veil, and causing the veil to deviate in its generally downward direction of travel. In its simplest embodiment, the lapping device of the present invention includes one low frequency sound generator having one resonator tube shaped for emission of low frequency sound and having an open end from which sound may be emitted to a portion of a veil. Preferably, the lapping device has two resonator tubes whose open ends are in spaced, opposing relationship, and in the preferred method low frequency sound is alternately applied at generally opposing locations near the veil, causing portions of the veil to deviate in generally alternate directions in its direction of travel.Type: GrantFiled: June 5, 1995Date of Patent: February 20, 2001Assignee: Owens Corning Fiberglas Technology, Inc.Inventors: David P.

Patent number: 6113818Abstract: A method of integrating organic fibers with mineral fibers includes centrifuging organic fibers from molten organic material, using a rotating organic fiber spinner, directing the organic fibers into a downwardly moving veil of organic fibers and gases, with the veil having an inwardly converging shape as it moves downward, centrifuging mineral fibers from molten mineral material using a rotary mineral fiber spinner positioned concentrically within the downwardly moving veil of organic fibers, directing the mineral fibers into a downwardly moving veil of mineral fibers and gases within the veil of organic fibers, wherein the veil of mineral fibers intersects with the veil of organic fibers to integrate the mineral fibers with the organic fibers, and collecting the integrated mineral fibers and organic fibers as a fibrous pack. An apparatus for performing the method is also disclosed.Type: GrantFiled: November 24, 1997Date of Patent: September 5, 2000Assignee: Owens Corning Fiberglas Technology, Inc.Inventors: Michael T.
