Abstract
Abstract Fabric suitable for use as a cotton bale cover or bag fabric comprising a woven substrate with a series of stripes of a thermoplastic resin fused thereto. This fabric permits sampling of cotton in a bale but prevents fraying of the fabric in this operation. Further, the fabric permits moisture to pass through the material stored therein. Apparatus and method for making the fabric are also shown.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
41 words
A fabric suitable for use as a cotton bale cover or bag fabric comprising a woven polyolefin substrate with a series of stripes of a thermoplastic resin fused thereto, said stripes preventing fraying of said substrate when said fabric is cut.
Claim 2
Dependent Claim
41 words
A fabric suitable for use as a cotton bale cover or bag fabric comprising a woven polyolefin substrate with a series of stripes of a thermoplastic resin fused thereto, said stripes preventing fraying of said substrate when said fabric is cut.
Claim 3
Dependent Claim
26 words
The fabric of claim 1 wherein said substrate is woven from polyethylene or polypropylene tape yarn and said stripes are selected from polymeric material bondable thereto.
Claim 4
Dependent Claim
12 words
The fabric of claim 2 in the form of a spiral tube.
Claim 5
Dependent Claim
26 words
The fabric of claim 1 wherein said substrate is woven from polypropylene tape yarn and said stripes are a blend of polypropylene and ethylene-methyl acrylate copolymer.
Claim 6
Dependent Claim
24 words
The fabric of claim 1 wherein said substrate is woven from polypropylene tape yarn and said stripes are a blend of polypropylene and polyethylene.
Claim 7
Dependent Claim
19 words
The fabric of claim 1 wherein said substrate is woven from polyethylene tape yarn and said stripes are polyethylene.
Claim 8
Dependent Claim
10 words
A cotton bale covered with the fabric of claim 1.
Claim 9
Independent Claim
62 words
A method of coating a woven polyolefin substrate with stripes of a thermoplastic resin comprising extruding said resin through a film coating die wherein a sheet of resin is extruded in molten form, cutting said sheet into a plurality of stripes, contacting said stripes with said substrate while said stripes are still molten under pressure to bond said stripes to said substrate.
Claim 10
Independent Claim
62 words
A method of coating a woven polyolefin substrate with stripes of a thermoplastic resin comprising extruding said resin through a film coating die wherein a sheet of resin is extruded in molten form, cutting said sheet into a plurality of stripes, contacting said stripes with said substrate while said stripes are still molten under pressure to bond said stripes to said substrate.
Claim 11
Dependent Claim
26 words
The method of claim 8 wherein said substrate is woven from polyethylene or polypropylene tape yarns and said stripes are selected from polymeric materials bondable thereto.
Claim 12
Dependent Claim
26 words
The fabric of claim 8 wherein said substrate is woven from polypropylene tape yarn and said stripes are a blend of polypropylene and ethylene-methyl acrylate copolymer.
Claim 13
Dependent Claim
118 words
Apparatus for making a stripe coated substrate comprising an extruder, a film die on said extruder, a striping deckle removably mounted on said die, said deckle provided with a plurality of fingers which contact the die orifice when said deckle is in place, a rubber nip roll and a chill roll, said nip roll and chill roll being so positioned as to form a nip therebetween, said nip roll and said chill roll located to receive in said nip film extruded from said die, a means to position adjustably the relative position of said die and said nip to permit material extruded from said die to be deposited on material on said nip roll upstream of said nip.
Claim 14
Dependent Claim
118 words
Apparatus for making a stripe coated substrate comprising an extruder, a film die on said extruder, a striping deckle removably mounted on said die, said deckle provided with a plurality of fingers which contact the die orifice when said deckle is in place, a rubber nip roll and a chill roll, said nip roll and chill roll being so positioned as to form a nip therebetween, said nip roll and said chill roll located to receive in said nip film extruded from said die, a means to position adjustably the relative position of said die and said nip to permit material extruded from said die to be deposited on material on said nip roll upstream of said nip.
Claim 15
Dependent Claim
18 words
The apparatus of claim 11 including means to pass substrate to said nip roll and through said nip.
Claim 16
Dependent Claim
28 words
A cotton bale covered with a fabric comprising a substrate woven from a polyolefin yarn, said substrate having a series of stripes of a thermoplastic resin fused thereto.
Claim 17
Dependent Claim
28 words
A cotton bale covered with a fabric comprising a substrate woven from a polyolefin yarn, said substrate having a series of stripes of a thermoplastic resin fused thereto.
Claim 18
Dependent Claim
17 words
The cotton bale of claim 13 wherein said fabric is in the form of a spiral tube.
Claim 19
Dependent Claim
26 words
The cotton bale of claim 13 wherein said polyolefin yarn is selected from the group consisting of a polyethylene tape yarn and a polypropylene tape yarn.
