Abstract
Un montaje de revestimiento arquitectónico incluye un tubo para enrollar giratorio, un revestimiento acoplado al tubo para enrollar giratorio, y los primeros y segundos tornillos de límite que tienen cada los primeros y segundos extremos. El segundo extremo del primer tornillo de límite puede acoplar el primer extremo del segundo tornillo de límite. Uno de los tornillos de límite se fija se forma giratoria y axial con respecto a una placa final. El otro de los tornillos de límite se puede mover entre las posiciones bloqueada de forma giratoria y desbloqueada de forma giratoria con respecto a la placa final. Las tuercas de límite se acoplan de forma roscada a las roscas exteriores de los tornillos de límite. En la posición bloqueada de forma giratoria uno de los tornillos de límite se fija de forma giratoria y axial con respecto a la placa final, y en la posición desbloqueada de forma giratoria el otro tornillo de límite se puede mover de forma giratoria con respecto a la placa final para ajustar un tope de extensión o retracción del revestimiento.
