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. Each handle has an insertion area, a collar area, and a gripping area. 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 handles and core have a means for coupling meaning that the core and the insertion area of the handles do not move independently from one another.
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; and,
a pair of handles, wherein each handle has a insertion area, a collar area, a gripping area, 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 and a length 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 handles and core comprise a means for coupling selected from the group consisting of the insertion area of the handles comprising at least one tab with the wall of the core comprising at least one matching recess and insertion area of the handles comprising at least one recess with the wall of the core comprising at least one matching tab, wherein the tabs and recesses have a length, and wherein the length of the tabs and recesses runs along the length of the generally cylindrical shape of the insertion area of the handles.
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 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.
4. The system of claim 1 , wherein the insertion area, collar area, and gripping area are one unitary piece.
5. The system of claim 1 , wherein the gripping area and the collar area are able to be rotated independent of the insertion area.
6. The system of claim 1 , further comprising the web wound onto the core.
7. The system of claim 6 , wherein the web comprises a fabric saturated with a curable polymer material.
8. The system of claim 1 , wherein the cylindrical object is a pipe or conduit.
9. 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.
