Claims
- 1. A suspendable web for suspension in a frame, comprising:
a fabric having an edge and a margin portion adjacent said edge; and a continuous plastic body bonded to said margin portion by extrusion of said plastic onto said fabric.
- 2. The suspendable web of claim 1, said fabric having two said edges and two said margin portions, and two said continuous plastic bodies, and a different one of said plastic bodies bonded to each of said margin portions by extrusion onto said fabric.
- 3. The suspendable web of claim 1, said fabric having interstices filled by said plastic.
- 4. The suspendable web of claim 1, said fabric being plastic.
- 5. A method for forming a suspendable web, said method comprising steps of:
providing a fabric having at least one edge and at least one margin portion adjacent the at least one edge; providing an extruder and plastic to be extruded by the extruder; moving the at least one margin portion through the extruder; extruding plastic onto the at least one margin portion to form a body along the at least one edge; and cooling the extruded plastic to bond the plastic body to the fabric.
- 6. The method of claim 5, said step of extruding including heating the plastic to a temperature sufficient for softening material forming the fabric, and extruding the plastic at the temperature.
- 7. The method of claim 5, including heating the margin portion to soften fibers in the web.
- 8. The method of claim 5, including a second step of extruding for extruding a second body on a second margin portion of the fabric along a second edge of the fabric opposite the first mentioned edge.
- 9. The method of claim 8, said first and second extruding steps performed simultaneously.
- 10. The method of claim 5, said step of extruding including applying streams of said plastic on opposite surfaces of said margin portion.
- 11. The method of claim 10, including pressing said applied streams of plastic with a die, and forcing extruded plastic into spaces around fibers of the fabric.
- 12. The method of claim 10, including extruding a second body on a second margin portion of the fabric along a second edge of the fabric opposite the first mentioned edge.
- 13. The method of claim 12, including heating the margin portions to soften fibers in the web.
- 14. The method of claim 12, said steps of extruding including heating the plastic to a temperature sufficient for softening fibers forming the fabric, and extruding the plastic at the temperature.
- 15. The method of claim 12, said second step of extruding including applying streams of said plastic on opposite surfaces of the second margin portion.
- 16. The method of claim 15, including pressing all said applied streams of plastic with dies, and forcing extruded plastic into spaces around fibers of the fabric.
- 17. The method of claim 15, said steps of extruding including heating the plastic to a temperature sufficient for softening material forming the fabric, and extruding the plastic at the temperature.
- 18. The method of claim 17, including pressing all said applied streams of plastic, and forcing extruded plastic into spaces around fibers of the fabric.
- 19. The method of claim 17, said first and second extruding steps performed simultaneously.
- 20. The method of claim 19, including pressing all said applied streams of plastic, and forcing extruded plastic into spaces around fibers of the fabric.
- 21. A suspendable web for suspension in a frame comprising:
a fabric having first and second edges on opposite sides of the fabric, and first and second margins adjacent said first and second edges, respectively, said fabric including a plurality of fibers; and a first continuous plastic body bonded to said first margin portion by extrusion of said plastic onto said fabric, with plastic material of said first plastic body embedded between fibers of said fabric; and a second continuous plastic body bonded to said second margin portion by extrusion of said plastic onto said fabric, with plastic material of said second plastic body embedded between fibers of said fabric.
- 22. The suspendable web of claim 21, said first plastic body and said second plastic body encapsulating said first edge and said second edge, respectively.
- 23. The suspendable web of claim 21, said fabric being plastic.
