<p>Apparatus for producing reinforced hose, in which a reinforcement layer forming device is coaxially arranged with respect to the outlets of an outer tube extruding machine and an inner tube extruding machine to continuously and simultaneously form an inner tube, form a reinforcement layer, and then extrude an outer tube, on a torpedo projected over the end of an inner tube die of the inner tube extruding machine. In order to stably obtain a reinforcement layer with a uniform spiral structure, the ends of inner and outer spinners (25) and (26) of frustoconical shape with thread holes (G1, G2) respectively of a spiral device (21) which is the reinforcement layer forming device are inserted into a gap between an intermediate die (12) and the inner tube die (2), and inner and outer bobbin carriers (22) and (23) of the spiral device (21) are arranged so as to rotate together.</p> |
