Abstract: A device for operating flexible elements includes a rotating drum around which flexible elements are wound to be advanced, a container of the drum equipped with a series of rubber rollers which hold the flexible elements in adherence with the outer surface of the drum and which has a longitudinal slot which permits passage of the flexible elements from the inside to the outside of the container, and a moving guide for the flexible elements positioned across the drum and which moves with reciprocating movement and facilitates winding or unwinding of the flexible elements on or from the drum.
