Abstract
Covers with a non-circular cross section are produced by assembling a continuous sheet of filaments on a roller, passing the continuous sheet of filaments from the roller to a mandrel, and spirally winding the continuous sheet of filaments on the mandrel with an impregnating resin. gives covers with a non-circular cross section e.g. an elliptic section or a square section with rounded corners. The continuous sheet of filaments can be wound onto the mandrel at a relatively high speed.
