Abstract: An extruder for continuously manufacturing reinforced fluid-impermeable tubing, especially hose, mainly comprises an elongated extruder head formed from an inner, an intermediate and an outer tubular member arranged concentric with each other and constructed to define between the inner and the intermediate tubular members a first annular passage having an outlet end communicating at an opposite end thereof with a first hopper, and to define between the intermediate and the outer tubular member a second annular passage communicating with a second hopper. A mandrel concentric with the inner tubular member forms a gap with the latter through which a tubular reinforcing fabric is guided.
