Appl. No.:

6/809998

Inventors:

Neil E. Greene - Granville OH

Randall E. Nyhart - Granville OH

Assignee:

Owens-Corning Fiberglas Corporation - Toledo OH

International Classification:

C03B 3702

US Classification:

65 2

Abstract:

A feeder for the production of glass filaments is provided with a shallow layer of glass over the discharge wall in combination with a fluid filled cavity capable of being pressure regulated to render the operation dripless or non-dripless as desired. Preferably, the feeder is rendered non-dripless when the restart of filament formation from idled orifices is desired.

Filed:

Mar 17, 1978

Appl. No.:

5/887705

Inventors:

Neil E. Greene - Granville OH
Seshadri Srinivasan - Pickerington OH
Leonard A. Stenger - Granville OH

Assignee:

Owens-Corning Fiberglas Corporation - Toledo OH

International Classification:

C03B 3702

US Classification:

65 1

Abstract:

The disclosure embraces a method of and apparatus for processing heat-softened fiber-forming mineral material, such as glass, to form fibers or filaments and particularly embraces a bushing block arrangement having one or more glass flow passages configurated to provide a minimum of contact of the bushing block with the glass in the flow passage or passages to stabilize the operating characteristics of a bushing or stream feeder, effect conservation of heat and improve bushing performance.

Appl. No.:

6/178269

Inventors:

Frederick M. Shofner - Knoxville TN
Neil E. Greene - Granville OH
Terry J. Hanna - Newark OH

Assignee:

Owens-Corning Fiberglas Corporation - Toledo OH

International Classification:

C03B 37025

US Classification:

65 2

Abstract:

A method and apparatus for monitoring the average diameter of a plurality of glass fibers, comprising illuminating the fibers with electromagnetic radiation, sensing radiation scattered by the fibers and generating a signal responsive to the amount of radiation sensed as an indication of the average diameter of the fibers; such signal can be used for measurement and/or control of the fiber producing process.

Apr 9, 1984

Appl. No.:

6/597578

Inventors:

Neil E. Greene - Granville OH
Terry J. Hanna - Newark OH

Assignee:

Owens-Corning Fiberglas Corporation - Toledo OH

International Classification:

C03B 37085

US Classification:

65 2

Abstract:

The present invention proposes a novel apparatus and method for the manufacture of glass fibers utilizing a bushing confining a body of molten glass over an orifice plate which may or may not have depending tips. Interposed in the glass body is a plate or other device for reducing the pressure of the molten glass body over the orifice plate to a pressure no greater than atmospheric pressure. The orifices are of relatively large diameter incapable of imposing a substantial pressure drop on molten glass flowing therethrough. Each tip contains a pool of molten glass at no greater than atmospheric pressure and, during fiber attenuation, a forming cone is drawn from the pool in each tip. The cones are located in the tips, each cone is smaller than the surrounding tip and each cone is stabilized on the interior tip wall by an annular glass portion integral with the cone. The process is dripless, since upon fiber interruption at any given tip, the molten glass pool remains in the tip.

International Classification:

C03B 37025

US Classification:

65 1

Abstract:

The present invention embraces apparatus and methods of forming mineral fibers, such as glass. Such invention comprising a mineral fiber forming bushing bottom wall comprising a plurality of tubular members attached together at adjacent sides to form a rigid structure adapted for flow of molten mineral material through the tubular members to form a layer of molten mineral material along the undersurface of the tubular members and rod members projecting below the undersurface of the tubular members. The rod members are attached to the tubular members and are adapted for flow thereon of the molten mineral material from the undersurface of the tubular members for attenuation into fibers.

Assignee:

Owens-Corning Fiberglas Corporation - Toledo OH

International Classification:

C03B 3708

US Classification:

65 2

Abstract:

A feeder system for the production of glass filaments is rendered dripless or non-dripless on demand by controlling the pressure of the air in contact with the streams and beads of the orificed discharge wall. Preferably, the feeder is rendered non-dripless when the restart of filament formation from idled orifices is desired.
