Abstract
Abstract The invention relates to a flexible hose formed of a wound web material and having its walls reinforced by wire windings, with the edges of successive web windings overlapping one another. In accordance with the invention, the longitudinal axes (Da) of the wires (13, 13', 13") and the longitudinal axis (ba) of the web material (3) extend at equal inclination with respect to the hose axis (A), and the reinforcement consists of at least two wire windings.
