Claim 19:
20. A CIPP liner reel, comprising:
a frame;
a core rotatably connected to the frame about an axis of rotation, wherein the core is adapted for winding a CIPP liner around the core and adapted for unwinding a CIPP liner from the core, the core comprising:
a left guide member attached to the core near a left end of the core;
a right guide member attached to the core near a right end of the core;
wherein the core comprises an opening disposed between the left guide member and the right guide member;
wherein the axis of rotation of the core is substantially perpendicular to the right guide member and the left guide member;
a connector disposed within the core and configured for connecting to the CIPP liner through the opening in the core, wherein the connector is attached to an interior surface of the core;
wherein the core is comprised of a cylinder and wherein the interior surface of the core that the connector is connected to faces the opening; and
