ABSTRACT:
An apparatus for manufacturing a fiber-reinforced pressure hose comprises a spiral winder which includes a mandrel of a truncated conical shape tapering one end towards the other end thereof at a predetermined angle of convergence and having its outer peripheral surface formed with a plurality of guide grooves lengthwise thereof. Longitudinal reinforcing strands are guided along the guide grooves on the mandrel while at least two circumferential reinforcing strands are spirally wound on the longitudinal reinforcing strands in the opposed direction with each other to form a tubular reinforcing layer. This reinforcing layer is, while being drawn in a direction away from the mandrel, positioned substantially intermediately of the wall of the subsequently formed tubular product.
