Abstract
A method of manufacturing a liner for reinforcing a pipe includes providing a continuous first reinforcing fibers extending in a first direction, moving the first reinforcing fibers in a machine direction such that the first direction is parallel to the machine direction, providing sheets of a material having second reinforcing fibers extending in a second direction, placing the sheets onto the moving first reinforcing fibers such that the second direction is substantially perpendicular to the first direction, and folding the sheets into a closed shape.
Claims10
A system for manufacturing a liner for reinforcing a pipe, the system comprising:
- a first supply of continuous first reinforcing material having first reinforcing fibers extending in a first machine direction;
- a first conveyor having a first conveyor belt capable of moving the continuous first reinforcing material on the first conveyor in the first machine direction;
- a second conveyor system movable relative to the first conveyor, the second conveyor system comprising:
- a supply of continuous second reinforcing material having second reinforcing fibers extending in a second machine direction that is perpendicular to the first machine direction;
- a second conveyor having a second conveyor belt that is capable of moving the second reinforcing material in the second machine direction;
- and
- a cutter that cuts the continuous second reinforcing material into discrete sheets of second reinforcing material, wherein the second conveyor is operable to place the discrete sheets onto the continuous first reinforcing material on the first conveyor such that the second reinforcing fibers are perpendicular to the first reinforcing fibers;
- and
- a mechanical folder for folding the discrete sheets into a closed shape.
