Abstract
Abstract A plastic mesh product having a series of overlapping ribbons is formed by bonding such plastic ribbons with a second set of plastic filaments as the ribbons and filaments extrude from relatively rotating dies. The ribbonlike filaments are extruded from orifices so positioned that only a portion of the width of the ribbon is bonded to the second filaments thus producing a plastic product with overlapping ribbons having a ''''fish scale'''' character.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
95 words
A plastic mesh, comprising a first group of parallel filaments forming an intersection with a second group of parallel ribbonlike filaments such that only a portion of the width of the filaments of said second group is bonded to filaments of said first group at said intersection, the spacing and width of said second group being such that the unbonded edges of the filaments of said second group overlap the bonded edges of adjacent filaments of said second group, said overlapping filaments being non-bonded to one another to allow fluids to circulate through said mesh.
Claim 2
Dependent Claim
95 words
A plastic mesh, comprising a first group of parallel filaments forming an intersection with a second group of parallel ribbonlike filaments such that only a portion of the width of the filaments of said second group is bonded to filaments of said first group at said intersection, the spacing and width of said second group being such that the unbonded edges of the filaments of said second group overlap the bonded edges of adjacent filaments of said second group, said overlapping filaments being non-bonded to one another to allow fluids to circulate through said mesh.
Claim 3
Dependent Claim
20 words
The mesh product of claim 1 wherein said ribbonlike filaments are from about one-half inch to about two inches wide.
Claim 4
Dependent Claim
70 words
A plastic mesh according to claim 1, wherein the filaments of said first group are of a ribbonlike form, the spacing and width of the filaments of said first group being such that the unbonded edges of the filaments of said first group overlap the bonded edges of adjacent filaments of said first group, said overlapping filaments being non-bonded to one another to allow fluids to circulate through said mesh.
Claim 5
Dependent Claim
47 words
A plastic mesh according to claim 1 including a third group of parallel filaments intersecting the filaments of said first group to form an open plastic net product having the overlapping ribbonlike filaments of said second group bonded to the filaments of said first and third groups.
Claim 6
Dependent Claim
12 words
A plastic mesh according to claim 1 wherein said plastic is opaque.
Claim 7
Dependent Claim
83 words
A plastic mesh comprising a first group of parallel spaced apart plastic filaments intersecting and bonded at said intersections to a portion of each filament of a second group of spaced apart parallel ribbonlike plastiC filaments, the distance between corresponding edges of adjacent ribbonlike filaments being less than the width of said ribbonlike filaments to locate said adjacent ribbonlike filaments in overlapping relation to one another, said overlapping ribbonlike filaments being non-bonded to one another to allow fluids to circulate through said mesh.
Claim 8
Dependent Claim
83 words
A plastic mesh comprising a first group of parallel spaced apart plastic filaments intersecting and bonded at said intersections to a portion of each filament of a second group of spaced apart parallel ribbonlike plastiC filaments, the distance between corresponding edges of adjacent ribbonlike filaments being less than the width of said ribbonlike filaments to locate said adjacent ribbonlike filaments in overlapping relation to one another, said overlapping ribbonlike filaments being non-bonded to one another to allow fluids to circulate through said mesh.
Claim 9
Dependent Claim
36 words
A plastic mesh according to claim 6 wherein each of said ribbonlike filaments defines a first plane forming an angle of less than ninety degrees with a second plane defined by said first group of filaments.
Claim 10
Dependent Claim
57 words
A plastic mesh according to claim 6 wherein the filaments of said first group are of a ribbonlike form, the distance between corresponding edges of adjacent filaments of said first group being less than the width of the filaments of said first group to locate adjacent filaments of said first group in overlapping relation to one another.
