In an apparatus for producing a tubular body with a membrane forming a separating wall extending across the interior of the tubular body, an injection mold is provided including a cylindrical hollow space corresponding to the outer wall of the tubular body and a pin is disposed in the cylindrical chamber in spaced relationship with the wall thereof so as to form a tubular passage, wherein the pin includes upper and lower parts which are movable relative to each other so as to form an adjustable gap between which is in communication circumferentially with the tubular passage.

Pour un appareil servant à produire un corps tubulaire avec une membrane qui forme une paroi de séparation qui traverse l'intérieur du corps tubulaire, un moule à injection est proposé, qui comprend un espace cylindrique correspondant à la paroi externe du corps tubulaire, ainsi qu'une tige placée dans la chambre cylindrique, à distance de la paroi du corps tubulaire, de façon à former un passage tubulaire. La tige comprend une partie supérieure et une partie inférieure mobiles l'une par rapport à l'autre de façon à former un espace réglable qui communique avec le passage tubulaire sur toute sa circonférence.
