Patent number: 8082760Abstract: A non-woven product having a core layer (32) containing dense particulate additive between adjacent layers (33) which are substantially free of additive is made by fiberizing a mineral melt on a spinner (1) comprising at least one fiberizing rotor (2, 3, 4) mounted for rotation about a substantially horizontal axis, and the resultant fibres are collected in air streams (5) as a cloud of fibres which travels towards a travelling collector (11) on which a web (14) is formed and carried out of the spinning chamber (9). Dense particles such as magnesium hydroxide are ejected from a suitable ejector (15) on to a baffle (16) by which they are deflected across the width of the chamber and lengthwise over the length of a intermediate collecting zone (B) to form the core layer (32) while the initial and final collecting zone (A and C) are substantially free of the dense particulate additive.Type: GrantFiled: August 16, 2006Date of Patent: December 27, 2011Assignee: Rockwool International A/SInventor: Lars Elmekilde Hansen

Patent number: 7574875Abstract: Device and method for chemical deposition on an elongated member of vitreous material in which a rotating gripping member causes a first end portion of the elongated member to rotate. The second end portion of the elongated member is borne by a pair of supporting members which are axially spaced apart (L1) and are capable of permitting angular rotational movement and axial sliding of the second end portion. Each supporting member also applies a radial constraint preventing the second end portion from moving away from the axis of rotation, thus forcing the second portion and the elongated member to lie with a longitudinal axis coaxial with the axis of rotation. Any curvature of the elongated member is corrected and recovered in this way.Type: GrantFiled: March 29, 2002Date of Patent: August 18, 2009Assignee: Fibre Ottiche Sud - F.O.S. S.p.A.Inventors: Alessandro Rossi, Franco Cocchini, Stefano Grieco

Patent number: 7562540Abstract: A fiberizing device includes a housing, a receiving seat mounted on the housing, and a drawing device. The receiving seat includes a receiving groove having a discharge port. The receiving groove receives molten fluid formed by heating waste. A heating device is provided for heating the molten fluid in the receiving seat. The drawing device draws the molten fluid from the discharge port to form a solid fiber after the molten fluid comes in contact with cool air. The solid fiber possesses excellent fire-resistant properties and thus can be used as fire-resistant materials.Type: GrantFiled: June 16, 2006Date of Patent: July 21, 2009Assignee: Green Material CorporationInventor: Yao-Chung Hu

Publication number: 20080156042Abstract: An apparatus for manufacturing high quality glass wool fibers, and more particularly to a spinner including a radiation shield is disclosed. The spinner includes a number of radiation shield positioned beneath the spinner base and decreases the temperature gradient along the peripheral sidewall of the spinner and improves the quality of the glass fibers. One suitable material for the radiation shield is a high temperature nickel alloy.Type: ApplicationFiled: December 28, 2006Publication date: July 3, 2008Inventors: Patrick M. Gavin, Michael T. Pellegrin, James S. Belt, Carmen A. LaTorre, Marc Alan Lucas

Publication number: 20080105000Abstract: A fiberizing device for producing fibers from waste includes a housing having an inlet for receiving molten fluid. Two rollers are rotatably mounted in the housing and include a space therebetween through which the molten fluid passes. Each roller is in contact with at least one centrifugal wheel. The molten fluid is driven through the space and rolled in the space by the rollers. The rolled molten fluid is drawn by the centrifugal wheel when the rolled molten fluid comes in contact with the centrifugal wheel, with the rolled molten fluid drawn by the centrifugal wheel being cooled to form solid fibers.Type: ApplicationFiled: November 3, 2006Publication date: May 8, 2008Inventor: Yao-Chung HU

Patent number: 6536241Abstract: At least two machines placed side by side, including a series of centrifuging wheels arranged in a cascaded manner and driven in rotation about axes all having substantially in a same direction. Two consecutive wheels rotate in opposite directions, and are simultaneously fed with material to be fiberized. The material is poured onto the first wheel, is accelerated, and is conveyed onto the second wheel, and then optionally onto following wheels, in order to be converted into fibers by centrifugal ejection, the fibers being picked up by a gas stream and collected by a gathering device. The main axes of two adjacent machines are positioned along a non-zero angle adjusted in order for two gas streams emitted by the two adjacent machines to meet and combine. Such machines may find application in the manufacture of products based on mineral fibers.Type: GrantFiled: March 13, 2000Date of Patent: March 25, 2003Assignee: Isover Saint-GobainInventors: Valerie Dupouy, Alain Debouzie

Patent number: 5891479Abstract: A apparatus of fabricating a multisegmented ball for an electrical twisting ball display device, which is made up of spheroidal balls rotatably disposed in an elastomer substrate. The ball is composed of segments arrayed substantially parallel to one another, each segment being adjacent to at least one other segment and to no more than two other segments, adjacent segments being adjoined to one another at substantially planar interfaces. The apparatus has a plurality of separator members, each separator member having two opposed surfaces and an edge region in contact with both of said surfaces. A liquid flow is associated with each separator member and one of the surfaces on the separator member. Each one of the liquid flows is provided across its associated separator members toward the edge region of the separator member. Each of the liquid flows is of a hardenable liquid material and has an optical modulation characteristic and a flow rate.Type: GrantFiled: July 10, 1997Date of Patent: April 6, 1999Assignee: Xerox CorporationInventor: Nicholas K.
