System for applying a web around a cylindrical object with even tension
View Patent ↗A system for applying a web around a cylindrical object with even tension containing a core having a generally cylindrical shape and a pair of handles. The wall of the cylindrical object contains a plurality of ribs spaced around the circumference, where each rib connects the inner diameter and the outer diameter and extends from the first end to the second end defining honeycomb areas within the wall. Each handle has a insertion area, a collar area, a gripping area, and at least 2 locating pins. The collar area is sandwiched between the insertion area and the gripping area and the insertion diameter is less than the inner diameter of the core at the first end and second end. The location pins extend from the collar area and are located such that the pins fit into the honeycomb areas within the wall of the core.
1. A system for applying a web around a cylindrical object with even tension comprising:
a core having a generally cylindrical shape with a circumference, a length, a wall, an inner diameter, an outer diameter, a first end, a second end, wherein the wall comprises a plurality of ribs spaced around the circumference, wherein each rib connects the inner diameter and the outer diameter and extends from the first end to the second end defining honeycomb areas within the wall; and,
a pair of handles, wherein each handle has a insertion area, a collar area, a gripping area, and at least 2 locating pins, wherein the collar area is sandwiched between the insertion area and the gripping area, wherein the insertion area of the handles have a generally cylindrical shape with a insertion diameter less than the inner diameter of the core at the first end and second end, wherein the insertion area is connected to the collar area, wherein the gripping area has a generally cylindrical shape with a gripping diameter, wherein the gripping area is connected to the collar area, wherein the locating pins have a locating pin length and are attached to the collar area and extend towards the insertion area, wherein the location of the pins in the collar area is such that the pins fit into the honeycomb areas within the wall of the core.
2. The system of claim 1 , wherein the core has a length of at least about 6 inches.
3. The system of claim 1 , wherein the core comprises at least 4 ribs.
4. The system of claim 1 , wherein the core comprise at least 8 ribs.
5. The system of claim 1 , wherein the ribs are evenly spaced around the circumference of the core.
6. The system of claim 1 , wherein the ribs and the honeycomb areas of the core are continuous along the length of the core.
7. The system of claim 1 , wherein the collar area of the handles have a generally circular cross-section and have a larger diameter than the insertion area of the handle and the inner diameter of the core.
8. The system of claim 1 , wherein the handles comprise at least 4 pins.
9. The system of claim 1 , wherein the insertion area, collar area, and gripping area are one unitary piece.
10. The system of claim 1 , wherein the gripping area and the collar area are able to be rotated independent of the insertion area.
11. The system of claim 1 , further comprising a web wound onto the core.
12. The system of claim 11 , wherein the web comprises a fabric saturated with a curable polymer material.
13. The system of claim 1 , wherein the cylindrical object is a pipe or conduit.
14. The system of claim 1 , wherein the insertion area is tapered where the insertion diameter is largest at the end of the insertion area closest to the collar area and smallest at the end of the insertion area farthest from the collar area.
15. A method of applying a web around a cylindrical object with even tension comprising:
obtaining a cylindrical object;
obtaining a core having a generally cylindrical shape with a circumference, a length, a wall, an inner diameter, an outer diameter, a first end, a second end, wherein the wall comprises a plurality of ribs spaced around the circumference, wherein each rib connects the inner diameter and the outer diameter and extends from the first end to the second end defining honeycomb areas within the wall; and,
wrapping a web around the core;
obtaining a pair of handles, wherein each handle has a insertion area, a collar area, a gripping area, and at least 2 locating pins, wherein the collar area is sandwiched between the insertion area and the gripping area, wherein the insertion area of the handles have a generally cylindrical shape with a insertion diameter less than the inner diameter of the core at the first end and second end, wherein the insertion area is connected to the collar area, wherein the gripping area has a generally cylindrical shape with a gripping diameter, wherein the gripping area is connected to the collar area, wherein the locating pins have a locating pin length and are attached to the collar area and extend towards the insertion area, wherein the location of the pins in the collar area is such that the pins fit into the honeycomb areas within the wall of the core;
inserting each handle into the core such that a portion of the insertion pins are located within the honeycomb areas of the core;
wrapping the web around the cylindrical object.
16. The method of claim 15 , wherein the ribs and the honeycomb areas of the core are continuous along the length of the core.
17. The method of claim 15 , wherein the collar area of the handles have a generally circular cross-section and have a larger diameter than the insertion area of the handle and the inner diameter of the core.
18. The method of claim 15 , wherein the handles comprise at least 4 pins.
19. The method of claim 15 , wherein the cylindrical object is a pipe or conduit.
20. The method of claim 15 , wherein the web is a woven textile comprising warp yarns in a first direction and weft yarns at approximately 90 degrees to the warp yarns.
21. The method of claim 15 , wherein the insertion area is tapered where the insertion diameter is largest at the end of the insertion area closest to the collar area and smallest at the end of the insertion area farthest from the collar area.
