The embodiments of the present disclosure provide a method of applying an outer wrap to a corrugated pipe. The method comprises receiving a corrugated pipe that is cut to length, determining a wrap type to be applied to the corrugated pipe, determining a flow rate for applying a wrap of the wrap type based on a type of plastic used in the wrap, a type of fiber used in the wrap, and the wrap type, and applying a wrap made of the type of fiber and the type of plastic to the corrugated pipe using the determined flow rate.

A helical winding unit includes a plurality of guides arrayed in a peripheral direction of a liner, and adapted to guide each of a plurality of fiber bundles supplied to the helical winding unit to the liner, and an opening member arranged downstream of the plurality of guides in a travelling direction of the fiber bundle, and including an inner peripheral surface for forming a hole, through which the plurality of fiber bundles are inserted from one side to the other side in the axial direction. A plurality of opening surfaces on which the plurality of fiber bundles travel while making contact are formed on the inner peripheral surface of the opening member, and a cross-sectional shape orthogonal to the axial direction of each opening surface is linear.

A continuous fabric for use in forming a repair liner for reinforcing a pipe. The fabric includes a top layer and one or more bottom layers. The width of the top layer is less than the width of the continuous fabric and the density of the top layer is less than the density of at least one of the at least one or more bottom layers. The top layer may serve as a guide for winding the fabric in an overlapping pattern about a mandrel so that the essentially only the top layer is visible in the fabric winding.
