Abstract
Abstract The suspended nets of this invention may be used for sports purposes, for example in lawn tennis, or for other purposes, for example as conveyor netting in drying agricultural produce. The nets are formed from a length of netting with rectilinear mesh and have at least one edge an edge band containing an organic thermoplastic, the band being folded upon itself and welded to itself within the mesh openings along the edge of the net. The looped portion of the band can receive a cord for suspending the net. Similar bands can be applied along other edges for protection or suspension of the net.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
74 words
A net comprising: a length of netting having edges, said netting being composed of flexible nonmetallic threads disposed in a rectilinear mesh; and an edge band comprising organic thermoplastic material folded upon itself to enclose at least part of each mesh of the outermost row of meshes along at least one of said edges of the netting and welded to itself only within each such mesh whereby the band is retained on the netting.
Claim 2
Dependent Claim
74 words
A net comprising: a length of netting having edges, said netting being composed of flexible nonmetallic threads disposed in a rectilinear mesh; and an edge band comprising organic thermoplastic material folded upon itself to enclose at least part of each mesh of the outermost row of meshes along at least one of said edges of the netting and welded to itself only within each such mesh whereby the band is retained on the netting.
Claim 3
Dependent Claim
40 words
A net according to claim 1 wherein said edge band comprises: a band of strong textile material having opposite faces; and a coating of thermoplastic synthetic resin on at least one face, said face being welded to itself as aforesaid.
Claim 4
Dependent Claim
47 words
A net according to claim 1 wherein said netting comprises: threads which include organic thermoplastic fibers or filaments, said threads crossing one another in a rectilinear mesh; and small molded elements of thermoplastic material individually molded about each crossing of said threads and bonding said threads together.
Claim 5
Dependent Claim
40 words
A net according to claim 1 wherein said edge band extends along one longitudinal edge of said netting, said band being folded to form a loop cable of receiving a suspensory cord for suspending the net by the said edge.
Claim 6
Dependent Claim
79 words
A net according to claim 1, wherein said edge band encloses at least part of each mesh of only the outermost row of said meshes along said one edge of said length of netting, the threads of said netting being of a plastic material, and said band being welded only to itself in areas located within the meshes of the outermost row, whereby the band and the threads defining the outermost row of meshes are not directly welded together.
Claim 7
Dependent Claim
99 words
A lawn tennis net comprising: a length of netting having edges, said netting being composed of flexible nonmetallic threads disposed in a rectilinear mesh; and an edge band comprising organic thermoplastic material folded upon itself to enclose at least part of each mesh of only the outermost row of meshes along at least one of said edges of the netting and welded to itself only within each such mesh whereby the band is retained on the netting and a looped portion is formed at the fold; and a suspensory cord passing through the looped portion of the edge band.
Claim 8
Dependent Claim
99 words
A lawn tennis net comprising: a length of netting having edges, said netting being composed of flexible nonmetallic threads disposed in a rectilinear mesh; and an edge band comprising organic thermoplastic material folded upon itself to enclose at least part of each mesh of only the outermost row of meshes along at least one of said edges of the netting and welded to itself only within each such mesh whereby the band is retained on the netting and a looped portion is formed at the fold; and a suspensory cord passing through the looped portion of the edge band.
Claim 9
Independent Claim
134 words
A method of making a net which comprises the steps of: providing a length of netting of flexible nonmetallic threads disposed in a rectilinear mesh; providing a band having thermoplastic material on at least one face thereof; relatively positioning said band adjacent an edge of said length of netting; then folding said band laterally upon itself to enclose at least part of each mesh of only the outermoSt row of meshes along said edge of said length of netting, said band being folded so that said one face is folded upon itself; and then welding said band to itself only in an area within each such mesh while avoiding contact between the threads of the netting and the areas of the band being welded to prevent said threads from being welded to said band.
Claim 10
Independent Claim
134 words
A method of making a net which comprises the steps of: providing a length of netting of flexible nonmetallic threads disposed in a rectilinear mesh; providing a band having thermoplastic material on at least one face thereof; relatively positioning said band adjacent an edge of said length of netting; then folding said band laterally upon itself to enclose at least part of each mesh of only the outermoSt row of meshes along said edge of said length of netting, said band being folded so that said one face is folded upon itself; and then welding said band to itself only in an area within each such mesh while avoiding contact between the threads of the netting and the areas of the band being welded to prevent said threads from being welded to said band.
