An apparatus for producing a ribbed hose which is capable of effectively producing a ribbed hose irrespective of a diameter or size of a hose while preventing the apparatus from being large-sized. A cylinder is formed therein with a hose feed passage and a first drive mechanism is arranged for driving the cylinder. Also, a screw is arranged in parallel to the hose feed passage and driven by a second drive mechanism. The screw is provided on a distal end thereof with a nozzle, which is adapted to revolve around the hose to form a rib on a hose.
La présente invention a pour objet une machine de dimensions réduites servant à la fabrication d'un boyau nervuré et capable de produire un boyau nervuré de diamètres et de calibres divers. Un cylindre est formé à l'intérieur de la machine avec un passage d'alimentation de boyau; un premier mécanisme d'entraînement assure l'avance du cylindre. Une vis montée parallèlement au passage d'alimentation de boyau est commandée par un deuxième mécanisme d'entraînement. La vis en question comporte à son extrémité distale une filière conçue pour tourner autour du boyau et donner à celui-ci sa forme nervurée.
