Abstract
A method of producing a collar on a cylindrical composite fiber body, wherein the composite fiber body has a longitudinal axis and wherein a plurality of layers of resin impregnated fiber windings are wound to form the composite fiber body, after which the resin is hardened, includes the following steps: (a) forming a bead by winding resin impregnated fiber windings circumferentially about the cylindrical composite fiber body such that the bead has continuously rising flanks on both longitudinally spaced sides; (b) providing two clamping sleeves, each clamping sleeve having an end face extending substantially orthogonally to the longitudinal axis of the composite fiber body, a conical surface portion adjacent the end face, and an interior surface portion which is adjacent the conical surface portion and which conforms to the outer surface of the cylindrical composite fiber body; (c) applying the clamping sleeves about the composite fiber body while the composite fiber body is still wet, such that each end face lies against a respective one of the flanks; (d) tightening the clamping sleeves about the composite fiber body while the composite fiber body is still wet; (e) forming a collar between the end faces while the composite fiber body is still wet, by winding resin impregnated fiber windings circumferentially about the bead; and (f) loosening and releasing the clamping sleeves.
