Device for a blind with substantially horizontal unwinding

摘要

The sheet 1 which is wound on a winding drum 3 supported in a rotating manner by one A of the two walls is firmly fixed to straps 5 which are sent back by idle pulleys 6 carried on the opposite wall B so as to be wound on lateral cylinders 8 locked to the same shaft 4 which drives the said drum. Compensators 10 are provided on the straps 5 in order to elastically absorb the variations in length due to the inverse variations in the winding diameters of the sheet and of the straps during the operation of the device. <IMAGE>
