A method for producing a seamless metallic belt without a welded line and capable of being easily produced in high accuracy. A seamless belt material 21 having a defined length as a whole is placed on a core 11 and is held in a stretching state on the core 11 thermally expanded by heating, and further, in the above state, an outer circumference of the belt material 21 is cut to a predetermined thickness. The seamless metallic belt 20 is obtained by removing after the core 11 is cooled.
Méthode pour produire une courroie métallique sans joint ni soudure et pouvant se fabriquer facilement avec une grande précision. Un matériau de courroie 21 sans joint ayant globalement une longueur définie est placé sur un noyau 11 et maintenu en état d'étirement sur le noyau 11 thermiquement dilaté par chauffage et en outre, dans l'état susmentionné, une circonférence extérieure du matériau de courroie 21 est découpée à une épaisseur déterminée. La courroie métallique sans joint 20 est obtenue par enlèvement après refroidissement du noyau 11.
