A spinner disc for a rotary fiberization process, includes a base plate and an annular peripheral sidewall extending upward from the base plate which has a plurality of rows of fiberizing holes therein for fiberizing molten thermoplastic fiberizable materials by centrifugal force. The base plate has: a central bore therein on a rotational axis of the spinner disc for mounting the spinner disc on a drive shaft; an outer annular portion for receiving molten thermoplastic fiberizable materials to be fiberized; and an inner annular portion intermediate the central bore and, the outer annular base plate portion. A plurality of slits in the inner annular portion of the base plate, passing completely through the base plate from an upper surface of the base plate to a lower surface of the base plate and radiating outward from a periphery of the central bore, relieve stresses in the base plate, especially during a start-up of a fiberizing process, and permit hot gases to pass out from within the spinner disc during a fiberizing operation to heat the underside of the spinner disc.

Provided is a method of rolling a single-ply membrane sheet having seam tape applied along one edge. The method permits rolling the sheet quickly and easily, and allows the rolled sheet to be readily shipped. The method comprises folding the sheet with a single fold so that the edge with the seam tape opposes the opposite edge, and then rolling the folded sheet.

This invention involves apparatus and methods for making fibers by passing a molten material like glass, polymer, etc. through orifices or tips in a fiberizing bushing and then cooling the molten material coming from the tips and newly formed fibers with a cooling apparatus. The cooling apparatus is made from a metal to withstand the environment close beneath a fiberizing bushing and to provide the needed thermal conductivity to carry heat away rapidly. Alloys comprising nickel and titanium and that are in a martensite structure below about 200 degrees F. are used for at least parts of the cooling apparatus to reduce cost and/or provide for improved life and cooling performance and/or to improve fiberizing efficiency.

Provided is a method of rolling two single-ply membrane sheets having seam tape applied along one edge. The method comprises placing a first sheet on top of a second sheet, with the seam tape edge of each sheet at opposite ends and with the non-seam tape edge of each sheet overlying the seam tape of the other sheet. The two sheets can then be quickly rolled for easy transport to a job site.

This invention involves apparatus and methods for making fibers by passing a molten material like glass, polymer, etc. through orifices or tips in a fiberizing bushing and then cooling the molten material coming from the tips and newly formed fibers using cooling tubes. The cooling tubes are made from precious metals and various alloys comprising precious metals, nickel and one or more of titanium, chromium, molybdenum, etc. The one or more fins attached to the top surface of a hollow tube to make the cooling tubes contain spaced apart gaps, notches and/or slots extending from the top edge of the fin to prevent warping of the fins and to make the cooling tube more bendable, adjustable during the operation of making fibers from molten material.
