Apparatus for manufacturing a tubular product, includes a winding station (130) for winding a substrate component (104) and a reinforcement element (118) in a helical path to form a reinforced tubular product, and respective means (132, 110) for feeding the elongate substrate component and the elongate reinforcement element to the winding station. First severing means (200) cuts the reinforcement element upstream of the winding station, whereupon delivery of the reinforcement element upstream of the cut is withheld for a predetermined time period that results in a segment (239) of the tubular product without the reinforcement element. Second severing means (240) severs the tubular product within the above said segment to provide the predetermined length of the tubular product.
L'invention concerne un appareil permettant de fabriquer un produit tubulaire, qui comprend une station d'enroulement (130) conçue pour enrouler un composant substrat (104) et un élément de renforcement (118) dans un chemin hélicoïdal afin que soit formé un produit tubulaire renforcé, et des moyens respectifs (132, 110) conçus pour amener le composant substrat et l'élément de renforcement allongé dans la station d'enroulement. Un premier moyen de séparation (200) coupe l'élément de renforcement en amont de la station d'enroulement, la distribution de l'élément de renforcement en amont de la coupure étant maintenue pendant une durée prédéterminée afin d'obtenir un segment (239) du produit tubulaire sans l'élément de renforcement. Un deuxième moyen de séparation (240) sépare le produit tubulaire dans ledit segment afin d'obtenir la longueur prédéterminée du produit tubulaire.
