Patent ID: 8596917

Claim:
A system for reinforcing pipe structures comprising: a spool assembly comprising a rotatably mounted spool; a continuous length of tensile reinforcement material wound on and extending from said spool, and being deployable from said spool upon rotation of said spool about a central axis of said spool; said spool assembly being rotatably mounted so as to rotate said spool assembly about an axis that is perpendicular to said central axis of said spool; and a pusher receiving said tensile reinforcement material and configured to push said tensile reinforcement material against an interior surface of a pipe structure and into a helical winding adjacent said interior surface of said pipe; wherein said system is configured to rotate said tensile reinforcement material about a central axis extending through said tensile reinforcement material, and in a direction that relieves the torsional stress that is created by the act of helically winding said reinforcement material.
