  • the insert 2a can be one or more parts (two or more parts).
  • the use of a multi-part insert 2 has the advantage that it can be more easily removed from the opening 8, since it is divided from the tube 1 before removal.
  • the Ver- Turning a thermoplastic elastomer for the tube 1 allows a particularly simple removal of the insert 2 through the opening 6. Thus, for example, an end portion of the opening 6 is pulled over an end edge of the insert 2 and the insert 2a are removed through the opening 8.
  • the opening 6 can be closed by welding edge regions of the opening 6 together, if an endless tube 1 without opening 6 is desired.
  • a valve can be used in the opening 6, if an endless tube 1 without opening 6 is desired.

Abstract

L'invention concerne un procédé de fabrication d'un tube sans fin annulaire fermé à partir d'un tube (1) ouvert fabriqué en plastique pourvu d'une première extrémité ouverte (2) et d'une deuxième extrémité ouverte (3), selon lequel, lors d'une étape i), au moins un insert (2a) en un matériau autre que le matériau du tube (1) est introduit au moins par segments par le biais de la première extrémité ouverte du tube (1) dans ce dernier et la deuxième extrémité ouverte (3) du tube (1) étant tirée par le biais de l'insert (2a) et de la première extrémité ouverte (2), une zone du tube (1) s'étendant dans la première extrémité (2) et une zone du tube (1) s'étendant dans la deuxième extrémité (3) se chevauchant au moins par segments dans la région de l'insert (2), selon lequel, lors d'une étape ii), les zones du tube se chevauchant étant soudées ensemble dans la région de l'insert (2), selon lequel, lors d'une étape iii), l'insert (2a) est retiré par une ouverture réalisée dans le tube sans fin (1).
