Abstract

Abstract Glass fibers coiled in layers into a generally tubularly shaped package, and in which the layer of fibers adjacent one of its generally cylindrical shaped surfaces, is adhered to the surface of a support by a tacky or adhesive material. The degree of tack is such as to hold the layer of coils in position on the support even though the remainder of the layers of coils have been removed, at least to a degree where they no longer support the remaining layer of coiled fibers. The degree of adhesion is such as to allow the adhered fibers to be pulled from the surface of the support without damage to the fibers. The support can be a sheet material, and in the preferred embodiment, is applied to the outside generally cylindrical surface of a tubular package of fibers to form one part of a protective container for the package. Caps may be telescoped over the opposite ends of the package to cooperate with the sheet material and completely incase the package of glass fibers.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 125 words
A package of glass fibers comprising: a strand of glass fibers coiled in layers into a generally tubularly shaped package having a generally cylindrically shaped outer surface, sheet material extending around said cylindrically shaped surface of said package, and a high viscosity liquid having a viscosity between approximately 700 and approximately 5,000 poises penetrating the space between fibers of the coils of the strand forming at least the outermost layer of coils of the package, said high viscosity liquid extending between said fibers and said sheet material to provide greater resistance to flow in the space between said fibers than in the space between said strand and said sheet material, and whereby the layers of glass fibers can be removed without the coils slumping together.
Claim 2
Dependent Claim 125 words
A package of glass fibers comprising: a strand of glass fibers coiled in layers into a generally tubularly shaped package having a generally cylindrically shaped outer surface, sheet material extending around said cylindrically shaped surface of said package, and a high viscosity liquid having a viscosity between approximately 700 and approximately 5,000 poises penetrating the space between fibers of the coils of the strand forming at least the outermost layer of coils of the package, said high viscosity liquid extending between said fibers and said sheet material to provide greater resistance to flow in the space between said fibers than in the space between said strand and said sheet material, and whereby the layers of glass fibers can be removed without the coils slumping together.
Claim 3
Dependent Claim 14 words
The package of claim 1 wherein the high viscosity liquid includes a viscosity stabilizer.
Claim 4
Dependent Claim 15 words
The package of claim 2 wherein the high viscosity liquid is a saturated polyester resin.
