Machine for the wet and dry treatment of fabrics in rope or open-width form

A machine for the wet and dry treatment of fabrics in rope or open-width form comprising a treatment tank internally containing means for conveying the fabric in the form of an endless loop such as to draw the fabric from the bottom of the tank and feed it to strike a fulling place and a spray nozzle for wetting the fabric, wherein said conveying means comprise at least one belt conveyor oriented towards said fulling plate, said conveyor having an active upper branch and a lower return branch, the upper branch of the conveyor being surrounded by a transporter channel having open entry and exit ends, into which channel, in the vicinity of its entry end, a duct opens for feeding a compressed air stream onto the upper branch of the belt conveyor which passes longitudinally through said transporter channel, the air stream fed by said duct into said channel having a flow component oriented in the direction in which the upper branch of the conveyor advances through the channel and a component normal to said conveyor upper branch, so as to exert a pneumatic pressure on the fabric conveyed by the conveyor.
