US Patent:

Filed:

May 4, 1995

Appl. No.:

8/435010

Inventors:

William A. Watton - Pickerington OH
James G. Snyder - Newark OH

Assignee:

Owens Corning Fiberglas Technology, Inc. - Summit IL

International Classification:

D01D 518
C03B 3704

US Classification:

425 8

Abstract:

A fiber manufacturing apparatus including a spinner, fixed to one end of a rotatable shaft and equipment for supplying at least one molten thermoplastic material to the spinner is provided. The spinner includes a radial wall and an outer peripheral wall. The radial wall extends radially out from the shaft and has an outer periphery. The peripheral wall is disposed around the outer periphery of the radial wall and has a plurality of orifices for centrifuging fibers from at least one molten thermoplastic material. The spinner is operatively adapted to be radially balanced during the centrifuging operation. By being so balanced, the spinner is less likely to exhibit temperature induced deformation that introduces undesirable process variables during the fiber manufacturing process.

Abstract:

A spinner is adapted to be fixed at one end of a rotatable shaft in a fiberizer, the spinner including a radial wall extending radially out from the shaft and having an upper surface, a dam separating the upper surface into an inner portion and an outer portion, a lower surface, at least one first flow hole connecting the upper surface to the lower surface, and at least one second flow hole connecting the inner portion and the outer portion of said upper surface, and an outer peripheral wall connected to the radial wall and having a plurality of orifices therethrough.

Inventors:

James G. Snyder - Newark OH

Assignee:

Owens Corning Fiberglas Technology, Inc. - Summit IL

International Classification:

D01D 518

US Classification:

425 8

Abstract:

A fiber manufacturing apparatus including a spinner, mounted on one end of a rotatable shaft, and a source supplying two streams of at least one molten thermoplastic material to the spinner. The spinner includes a radial extension, a radial wall, and an outer peripheral wall. The radial extension is mounted to and extends radially out from the shaft. The radial wall is mounted to and extends radially out from the radial extension. The radial wall includes an upper surface, a lower surface, and an outer periphery. The peripheral wall is disposed around the outer periphery of the radial wall and has a plurality of orifices for centrifuging fibers from at least one molten thermoplastic material. During the operation of the spinner, the radial extension directs one stream of molten thermoplastic material through at least one flow hole to the lower surface of the radial wall and to orifices of the peripheral wall. As the spinner rotates, another stream of molten thermoplastic material is deposited directly onto the upper surface of the radial wall and travels along the upper surface to orifices of the peripheral wall.

Appl. No.:

8/395542

Inventors:

James G. Snyder - Newark OH

Assignee:

Owens Corning Fiberglas Technology, Inc. - Summit IL

International Classification:

B29B 900

US Classification:

425 8

Abstract:

Apparatus is provided for extending the life of spinners by means of reinforcement which includes a plurality of arms secured to the bottom wall of a spinner either individually or via an annular plate from which the arms extend. The reinforcement applies a radially inward force on a flange extending from the top or center of an outer sidewall of the spinner. The arms exert the radial force as the result of offset cams, due to a prestressed condition which is released after the reinforcement is installed in a spinner or otherwise. If the spinner includes both a center flange and an upper flange, the reinforcement may be installed to engage the center flange with gussets interconnecting the center flange and the upper flange at least at locations corresponding to the reinforcement to thereby provide reinforcement for both flanges. If the reinforcement is formed integrally as an annular plate with arms extending therefrom, the flange to be directly reinforced can be notched to receive the reinforcement by a bayonet coupling motion.
