  • Patent number: 6044666
    Abstract: An insulating flow block having a plurality of bores extending therethrough to permit the flow of molten fiberizable material through the block, a bushing assembly having a bushing block with one or more bores extending through a peripheral region thereof to divert a portion of a supply of molten fiberizable material from a central region of the bushing block to the peripheral region of the bushing block, and a bushing positioned in general registry with the bore of the peripheral region of the bushing block to facilitate the flow of molten fiberizable material to a peripheral region of the bushing is disclosed.

  • Patent number: 6020065
    Abstract: The present invention provides multifilament reinforcing articles which include fibers coated and impregnated with at least a partially cured, moisture reduced residue derived from an aqueous coating composition in which the major polymeric component is an elastomeric polymer. The coated and impregnated fibers are bound with a polymeric film-forming binder in the form of a tape, wire or other shape-retaining arrangement in which the fibers are substantially parallel. In an alternative embodiment, bundles of sized fibers are bound together in a shape-retaining arrangement by an aqueous coating composition including an aqueous emulsion of a thermoplastic polymer and water in an effective amount to bind the plurality of fiber bundles together, the aqueous coating composition being free of a crosslinking material.

  • Patent number: 6012672
    Abstract: A radially expandable endcap adapted for mounting upon a mandrel of a collet of a forming package winder. Other aspects of this invention include a collet and winder including the above endcap and method for winding strand using the same. Another aspect of the present invention is a collet having an expandable mandrel on at least a portion of a first end of the collet proximate an operator and distal to a second, opposite end of the collet mounted upon a support. Other aspects of this invention are a winder including the above collet and a method for using the same.

  • Patent number: 6013733
    Abstract: Curable coating compositions comprising either a liquid or particulate curable film-forming resinous material, a flow control agent which is a copolymer and optionally a carrier for the liquid resinous material. The copolymer is from at least one non-amino, non-hydroxyl and non-acid functional alkyl acrylate or methacrylate containing from 1 to 20 carbon atoms in the alkyl group, and functional monomer of either (i) amino functional acrylates and methacrylates in an effective amount to give the copolymer an amine value in the range from 2 to 70, or (ii) acid functional acrylate and methacrylate in an effective amount to give the copolymer an acid value in the range of from 10 to 30. Additionally, with either functional monomer (i) or (ii) another functional comonomer (iii) can be present in the copolymer which is hydroxyalkyl acrylate and/or hydroxyalkyl methacrylate and/or caprolactone polyol monomer.
