Abstract
Abstract Netting in the form of an extruded plastic mesh is provided for wrapping round bales of crop material. The netting includes longitudinal strands and tranverse strands fused together at intersecting joints to define rectangularly shaped openings in the netting. The minimum elasticity of the netting is about 15% before tensile failure in a longitudinal direction in order to prevent the netting from shrinking in a transverse direction. The netting thus maintains its original width dimension when pulled lengthwise.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
85 words
In combustion with a cylindrically shaped round bale of crop material, netting for wrapping the outer surface of said round bale in a circumferential direction, said netting comprising a plurality of longitudinal strands extending circumferentially of said round bale and a plurality of transverse strands extending longitudinaly of said round bale, said netting having sufficient elasticity in said circumferential direction to thereby prevent said netting from shrinking longitudinally of said round bale when the outer surface of said round bale is wrapped with said netting.
Claim 2
Dependent Claim
85 words
In combustion with a cylindrically shaped round bale of crop material, netting for wrapping the outer surface of said round bale in a circumferential direction, said netting comprising a plurality of longitudinal strands extending circumferentially of said round bale and a plurality of transverse strands extending longitudinaly of said round bale, said netting having sufficient elasticity in said circumferential direction to thereby prevent said netting from shrinking longitudinally of said round bale when the outer surface of said round bale is wrapped with said netting.
Claim 3
Dependent Claim
122 words
In combination with a cylindrically shaped round bale of crop material, netting for wrapping the outer surface of said round bale in a circumferential direction, said netting comprising a plurality of longitudinal strands extending circumferentially of said round bale and a plurality of transverse strands extending longitudinally of said round bale, said longitudinal and transverse strands being arranged substantially perpendicular to each other and being fused together at a plurality of intersecting joints to define a plurality of rectangular openings in said netting so that crop material in the outer surface of said round bale pokes through said plurality of rectangular openings when the outer surface of said round bale is wrapped with said netting to thereby hold said round bale together.
Claim 4
Dependent Claim
122 words
In combination with a cylindrically shaped round bale of crop material, netting for wrapping the outer surface of said round bale in a circumferential direction, said netting comprising a plurality of longitudinal strands extending circumferentially of said round bale and a plurality of transverse strands extending longitudinally of said round bale, said longitudinal and transverse strands being arranged substantially perpendicular to each other and being fused together at a plurality of intersecting joints to define a plurality of rectangular openings in said netting so that crop material in the outer surface of said round bale pokes through said plurality of rectangular openings when the outer surface of said round bale is wrapped with said netting to thereby hold said round bale together.
Claim 5
Dependent Claim
20 words
The netting of claim 1, wherein said longitudinal and transverse strands are connected together at a plurality of intersecting joints.
Claim 6
Dependent Claim
16 words
The netting of claim 3, wherein said netting is an extruded plastic mesh formed of polyethylene.
Claim 7
Dependent Claim
16 words
The netting of claim 3, wherein said netting is an extruded plastic mesh formed of polypropylene.
Claim 8
Dependent Claim
21 words
The netting of claim 3, wherein said longitudinal and transverse strands define a plurality of rectangularly shaped openings in said netting.
Claim 9
Dependent Claim
26 words
The netting of claim 6, wherein said pluralities of longitudinal and transverse strands are arranged substantially perpendicular to each other to define said rectangularly shaped openings.
