A reinforced pipe or hose comprises a tubular body (36) extruded from plastics or rubber material and braid reinforcement. The reinforcement is produced by applying one or more flexible reinforcing filaments (68), via guide means (70), to the external surface of the extruded tubular body (36) which is advanced relative to the guide means whilst the guide means is rotated about the body and simultaneously reciprocated parallel to the longitudinal axis of the body. The pitch of the resulting windings is computer-controlled with reference to the rate of rotation of the guide means (70) and rate of advance of the body (36) so that oppositely directed windings are applied with generally equal pitch angles and a braid reinforcement is provided having a pattern parallelogram configuration. |
