<p>An automated raising machine comprising a carrier structure (12, 51'), at least one drum (13, 52) revolving around a shaft (14, 539) driven to revolve by a motor (15, 519) and carrying two sets of alternating pile and counter-pile raising cylinders (16, 57, 17, 58), with such sets of cylinders being driven to revolve by independent drive means according to independent revolution directions, one pair of revolving brushes (21, 22; 56, 56') for cleaning said cylinders, in which at least one of said brushes is driven to revolve by a motor means (23; 510, 510') which determines the control and regulation of its angular speed. The revolution motion can be transmitted to the brushes by means of a transmission and one single motor means for said brushes, or by means of one single motor means for each brush. The motor means are controlled and fed with power by a electrical-electronic system, with sensors (35, 38, 39; 53, 55, 55') being provided which detect, instant-by-instant, the angular position of the drum and of the brushes and send signals to the electronic system which verifies the correct timing thereof.</p> |
