Abstract
Abstract @ An improved resin-coated fiberglass knit tape is disclosed which is highly extensible in the lengthwise direction and heat-set to alleviate fraying at cut ends. Heat-setting with essentially no tension on the tape accounts for retention of good extensibility. The invention is especially applicable to the field of orthopedic casting tape.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
115 words
A method of forming a storage-stable, resin-coated, knitted fiberglass tape having improved extensibility and resistence to fraying comprising: a. heating a length of knitted fiberglass tape having extensibility of at least 22 percent in the lengthwise direction essentially without tension for a time sufficient to set said fabric at least to the extent a ten-inch length of said fabric is set by heating at 800°F for 3 minutes; b. coating said fiberglass tape with a liquid resin; c. cutting said resin-coated tape into lengths suitable for the intended use of the tape; and d. packaging said resin-coated tape in a package suitable to prevent the curing of said resin prior to the time of use.
Claim 2
Independent Claim
115 words
A method of forming a storage-stable, resin-coated, knitted fiberglass tape having improved extensibility and resistence to fraying comprising: a. heating a length of knitted fiberglass tape having extensibility of at least 22 percent in the lengthwise direction essentially without tension for a time sufficient to set said fabric at least to the extent a ten-inch length of said fabric is set by heating at 800°F for 3 minutes; b. coating said fiberglass tape with a liquid resin; c. cutting said resin-coated tape into lengths suitable for the intended use of the tape; and d. packaging said resin-coated tape in a package suitable to prevent the curing of said resin prior to the time of use.
Claim 3
Dependent Claim
23 words
The method according to claim 1 wherein said length of knitted fiberglass tape is first wound onto a cylindrical core essentially without tension.
Claim 4
Dependent Claim
34 words
The method of claim 1, wherein said fabric is heated to set said fabric at least to the extent a 10-inch piece. of said fabric is set by heating at 1000°F for 3 minutes.
Claim 5
Dependent Claim
79 words
A storage-stable, resin-coated, knitted fiberglass tape comprising: a. a knitted fiberglass tape which has been heat-set to prevent fraying of cut ends of said tape; b. a liquid resin coated on said tape capable of curing to form a rigid article; and c. a package for said tape suitable to prevent curing of said resin prior to the time of use; said resin-coated tape having an extensibility of at least 20 percent in the lengthwise direction prior to curing.
Claim 6
Dependent Claim
79 words
A storage-stable, resin-coated, knitted fiberglass tape comprising: a. a knitted fiberglass tape which has been heat-set to prevent fraying of cut ends of said tape; b. a liquid resin coated on said tape capable of curing to form a rigid article; and c. a package for said tape suitable to prevent curing of said resin prior to the time of use; said resin-coated tape having an extensibility of at least 20 percent in the lengthwise direction prior to curing.
Claim 7
Dependent Claim
17 words
The fiberglass tape according to claim 4 wherein said liquid resin is a water-curable isocyanate-terminated polyurethane prepolymer.
Claim 8
Dependent Claim
12 words
The fiberglass tape according to claim 5 wherein said package is moisture-proof.
Claim 9
Dependent Claim
21 words
The fiberglass tape according to claim 4 wherein said resin-coated tape exhibits extensibility between 25 and 35 percent prior to curing.
