Abstract
Abstract A new fast method for making plastic netting without weaving or knitting. This non-woven netting is made by the cohesion of melting plastic monofilaments extruded by a T Die. Under the reciprocating movement of guide rollers, several groups of melting monofilaments are guided to be crossed, and the pressed and welded together on pressure silicone rollers. When necessary, other yarns or filaments can be added to be crossed, pressed and welded together, to increase the tensile strength of the netting. Generally, it is a kind of netting made by crossing one group of melting plastic monofilaments with other groups of melting plastic monofilaments or by other yarns under the pressing and welding process.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
147 words
A method for making non-woven plastic netting comprising the steps of: (1) extruding in a first direction in a first plane a first plurality of endless linear parallel spaced melted monofilaments; (2) feeding a second plurality of spaced endless strands across said first plurality of monofilaments in said first direction in said first plane; (3) during said feeding, reciprocally moving at least one of said first plurality of monofilaments and said second plurality of strands in a second direction nonparallel to said first direction in said first plane such that each of said plurality of strands overlaps at least two adjacent monofilaments of said first plurality of monofilaments; and (4) following steps 2 and 3, directing said first plurality of monofilaments and said second plurality of strands together between a pair of pressure rollers so as to weld said strands and monofilaments together to form said netting.
Claim 2
Independent Claim
147 words
A method for making non-woven plastic netting comprising the steps of: (1) extruding in a first direction in a first plane a first plurality of endless linear parallel spaced melted monofilaments; (2) feeding a second plurality of spaced endless strands across said first plurality of monofilaments in said first direction in said first plane; (3) during said feeding, reciprocally moving at least one of said first plurality of monofilaments and said second plurality of strands in a second direction nonparallel to said first direction in said first plane such that each of said plurality of strands overlaps at least two adjacent monofilaments of said first plurality of monofilaments; and (4) following steps 2 and 3, directing said first plurality of monofilaments and said second plurality of strands together between a pair of pressure rollers so as to weld said strands and monofilaments together to form said netting.
Claim 3
Dependent Claim
22 words
Method as in claim 1 wherein said second plurality of strands comprise a second plurality of endless linear spaced parallel melted monofilaments.
Claim 4
Dependent Claim
20 words
Method as in claim 1 wherein second plurality of strands comprise a second plurality of endless linear spaced parallel yarns.
Claim 5
Dependent Claim
48 words
Method as in claim 3 further comprising the step of feeding in said first direction a third plurality of parallel spaced strands of yarn into said first plane so as to cross said first and second pluralities of filaments and be welded thereto during said step of directing.
Claim 6
Dependent Claim
46 words
Method as in claim 4 further comprising the step of reciprocally moving said third plurality of strands of yarn in said second direction during said step of feeding said third plurality of strands of yarn so as to overlap said first and second pluralities of monofilaments.
Claim 7
Dependent Claim
142 words
A plastic non-woven netting formed by: (1) extruding in a first direction in a first plane a first plurality of endless linear parallel spaced melted monofilaments; (2) feeding a second plurality of spaced endless strands across said first plurality of monofilaments in said first direction in said first plane; (3) during said feeding, reciprocally moving at least one of said first plurality of monofilaments and said second plurality of strands in a second direction perpendicular to said first direction in said first plane such that each of said plurality of strands overlaps at least two adjacent monofilaments of said first plurality of monofilaments; and (4) following steps 2 and 3, directing said first plurality of monofilaments and second second plurality of strands together between a pair of pressure rollers so as to weld said strands and monofilaments together to form said netting.
Claim 8
Dependent Claim
142 words
A plastic non-woven netting formed by: (1) extruding in a first direction in a first plane a first plurality of endless linear parallel spaced melted monofilaments; (2) feeding a second plurality of spaced endless strands across said first plurality of monofilaments in said first direction in said first plane; (3) during said feeding, reciprocally moving at least one of said first plurality of monofilaments and said second plurality of strands in a second direction perpendicular to said first direction in said first plane such that each of said plurality of strands overlaps at least two adjacent monofilaments of said first plurality of monofilaments; and (4) following steps 2 and 3, directing said first plurality of monofilaments and second second plurality of strands together between a pair of pressure rollers so as to weld said strands and monofilaments together to form said netting.
