A method and apparatus for production of smooth or corrugated small and large diameter thermoplastic tubing and composite tubular structures. The apparatus comprises a supporting framework, a plurality of mold carriages mounted on said frame-work for reciprocal linear travel therealong, at least one mold block mounted on each of said mold carriages, each said mold block comprising a pair of opposed semi-cylindrical segments mounted on a carriage for transverse linear reciprocal travel there-along for closing and opening of said mold block, actuating means for moving said opposed mold segments towards and away from each other, and actuating means for selectively moving said carriages.
L'invention concerne un procédé et un appareil pour produire des tubes à surface lisse ou ondulée de petit et de grand diamètre et des structures tubulaires composites. L'appareil comprend un cadre de support, une pluralité de chariots porte-moule montés sur ledit cadre de manière à effectuer un mouvement linéaire d'aller et de retour sur celui-ci, au moins un bloc de moule monté sur chacun desdits chariots porte-moule, chacun desdits blocs de moule comprenant une paire de segments opposés semi-cylindriques montés sur un chariot pour un mouvement d'aller et de retour transversal permettant de fermer et d'ouvrir ledit bloc de moule, des moyens d'actionnement pour rapprocher et éloigner mutuellement lesdits segments opposés de moule, et un moyen d'actionnement pour déplacer sélectivement lesdits chariots.
