摘要 Disclosed is a method and apparatus for rolling wire mesh material such as ''''hex poultry netting.'''' According to the subject method the mesh material is cut forming an edge defined by a plurality of sharp wire ends. After a roll is formed, the edge is affixed to the body thereof to prevent unrolling and a cover is applied over the wire ends.
权利要求
1. A method for rolling mesh material and securing the outer end thereof and comprising the steps of: withdrawing a given length of wire mesh material from a source supplying a strip thereof; cutting through said strip of mesh material so as to separate therefrom said given length and form thereon an edge comprised of a plurality of strand ends; rolling said given length to form a roll with said edge as an outer end; fastening said edge to said roll so as to prevent unrolling thereof; and applying a material to said roll so as to cover said strand ends.
2. A method according to claim 1 further comprising a step of preforming said mesh material to impart a longitudinal curve thereto to reduce unrolling stresses.
3. A method according to claim 1 wherein said fastening step includes fastening the full length of said edge to said roll.
4. A method according to claim 1 wherein said fastening step and said applying step comprise a simultaneous packaging step.
5. A method according to claim 4 wherein said fastening and applying steps comprise locating an area of said mesh material that will be adjacent said edge when said rolling is completed, applying to the inner surface of said area a strip of flexible material with a first surface that is in contact with said inner surface; applying to the periphery of said roll a second strip of flexible material with a second surface so that said second strip spans said area and covers said strand ends and creating a bond between said second surface and said first surface through interstices in said mesh material.
6. A method according to claim 5 including the step of inserting between said first and second surfaces a removal means that can be actuated to break said bond and release said edge.
7. A method according to claim 5 wherein both of said surfaces comprise pressure sensitive adhesive.
8. A method according to claim 5 wherein said flexible materials comprise strips of thermoplastic material and said bonds are created by applying heat to said thermoplastic material.
9. A method according to claim 4 wherein said material comprises a strip with clamping means projecting therefrom; and said packaging step compriseS the step of locating an area of said mesh that will be adjacent said edge when rolling is completed, positioning said strip over said area with said clamping means projecting through interstices therein, displacing said clamping means so as to clamp said outer end to said area and cover said strand ends.
10. A method according to claim 9 wherein said strip is metallic and said clamping means comprise teeth projecting therefrom; and said displacing step comprises bending said teeth over said strand ends.
11. A method according to claim 10 wherein said positioning step comprises disposing said strip over the inner surface of said area with said teeth projecting through interstices in said area and through interstices directly adjacent said edge.
12. A method according to claim 4 wherein said packaging step comprises sandwiching said edge between a layer of mesh material adjacent thereto and a strip of pressure sensitive adhesive tape.
13. A method according to claim 4 wherein said packaging step comprises enclosing said edge and an adjacent portion of said mesh material in plastic material.
14. A method according to claim 1 wherein said fastening step comprises tucking one of said strand ends into the roll of mesh material and said applying step comprises applying said material around a periphery of said roll and over said edge.
15. A method according to claim 14 wherein said material is heat shrinkable and said applying step comprises applying heat to cause said material to shrink tightly over said edge.
16. A method according to claim 15 wherein said heat shrinkable material is tubular and encloses said roll of mesh material.
17. A method according to claim 16 wherein said heat shrinkable material comprises polyethylene film.
18. Apparatus for rolling mesh material and securing the outer end thereof and comprising: supply means for supplying a strip of mesh material; cutting means for separating a given length from the strip of mesh material so as to form an edge defined by a plurality of strand ends; spindle means for rolling said given length to form a roll with said edge as an outer end; and packaging means for applying to said edge a material that covers said strand ends.
19. Apparatus according to claim 18 including a preformer means for imparting a longitudinal curve to said given length so as to reduce unrolling stresses.
20. Apparatus according to claim 18 wherein said packaging means comprises locating means for locating an area of said given length that will be adjacent to said edge when rolling is completed, first applicator means for applying a first flexible strip of material with a first surface to the inside of said area, second applicator means for applying a second strip of flexible material with a second surface to the periphery of said roll so that said second strip covers said edge and said first surface and bonding means to bond said second surface to said first surface through interstices in said area of said given length.
21. Apparatus according to claim 20 wherein both of said interactive surfaces comprise pressure sensitive adhesive and said bonding means comprises pressure means.
22. Apparatus according to claim 18 wherein said material is heat shrinkable and said apparatus further comprises heating means for heating said material.
23. Apparatus according to claim 22 comprising a preformer means for imparting a longitudinal curve to said given length so as to reduce unrolling stresses.
