A strong, flexible glass fiber carrier and a method of making glass fiber using such a carrier wherein the carrier is of a helically wound forming tube construction for carrying glass fiber thereon in generally circular windings during glass fiber processing, the tube being characterized by having good wet strength and resistance to heat and centrifugal forces. The helically wound tube has a helically wound inner ply having a spiral joint, preferably a spiral butt joint, at least one helically wound intermediate ply having a spiral overlapped joint, a helically wound outer ply having a spiral overlapped joint, and a release coating on the outer ply. The spiral overlapped joint of the outer ply is stacked, or positioned, above the spiral joint of the inner ply to reinforce the latter; the spiral overlapped joint of the intermediate ply(s) is (are) staggered from the other joints of the tube. In the method of making glass fiber, a glass fiber strand is wound around the forming tube and further processed. At the end of the processing, the forming tube is partially collapsed and extracted from the interior of the circularly wound glass fiber.
