An opening and closing machine for architectural rolling door shutters is such that various parts of the machine are assembled into a cylindrical-shaped casing with a good work efficiency and without looseness. After a casing (6) is divided into upper and lower semi- cylindrical portions (9, 10) and various parts, such as an electric motor (12), of the machine are assembled into the lower semi-cylindrical portion (9), the upper semi-cylindrical portion (10) is slidingly fitted into and assembled to the lower semi-cylindrical portion and flange portions (9c, l0d) on the upper and lower semi- cylindrical portions (9, 10) in this state are clamped to each other and fixed in a state, in which the casing (6) is made small in diameter.

Cette invention se rapporte à une machine d'ouverture et de fermeture pour volets de portes enroulables de constructions architecturales, qui est conçue pour que diverses parties de la machine soient assemblées dans un logement de forme cylindrique avec une bonne efficience du travail et sans jeu. Après que le logement (6) a été divisé en parties semi-cylindriques supérieure et inférieure (9, 10) et après que diverses parties, comme le moteur électrique (12), de la machine ont été assemblées dans la partie semi-cylindrique inférieure (9), la partie semi-cylindrique supérieure (10) est ajustée par coulissement dans la partie semi-cylindrique inférieure, à laquelle elle est assemblée, et les parties brides (9c, 10d) se trouvant sur les parties semi-cylindriques supérieure et inférieure (9, 10) dans cette position sont serrées l'une contre l'autre et fixées dans cette position, dans laquelle le logement (6) se retrouve avec un diamètre réduit.
