Abstract: A machine for the wet and dry treatment of fabric in rope or open-width form of any type and weight has a treatment tank (10) within which the fabric to be treated is conveyed by a belt conveyor (11). The belt conveyor has an upper active conveying branch (15) and a lower return branch (16). The upper branch (15) of the conveyor is surrounded by an air transporter channel (22) with open ends and into which, in the vicinity of its entry end, a compressed air stream is fed to compress the fabric against the conveyor belt without the intervention of mechanical compression means the machine prevents the formation of creases in the fabric and allows treatment at a high effective rate.
