Abstract: An apparatus processes a fabric by repeated brushing on itself includes a process tumbler, provided with a feed duct for feeding the fabric in open-width form continuously between an infeed port and an outfeed port of the feed duct. An adjustment device for adjusting the passage section of the duct and associated with at least one of the ports. The adjustment device causes the passage section to be narrowed so that the fabric, which reaches the port in open-width form and is made to pass through a port in a first feed direction, is bunched into rope form and then allows the fabric, when made, to pass in the opposite direction through the narrowed passage section. The fabric is subtended by the other, wide port of the feed duct, to be stretched out from the rope form to the open-width form.

Abstract: A vibrating apparatus for dimensional stabilization treatment of fabrics includes a fabric-containing tub (2), a vibration-generating slider-crank mechanism (3) and a support mechanism (4) for supporting the tub (2) and transferring the vibrations produced by the generating mechanism (3). The tub (2) is made of carbon fiber and the mechanism (4) for supporting and transferring vibrations includes at least three rocker arms (12), each having one end hinged to the tub (2), the other end hinged to a counterweight (6) located opposite to the tub (2) and being hinged in the middle to a load-bearing structure (16).

Abstract: A machine for treating a fabric (T) with air, comprises a tunnel (10) for pneumatically transporting the fabric and means for injecting the air into the tunnel above and/or below the fabric and comprising at least one diverting valve (16;18) located substantially half way along the tunnel and having two channels (16a,16b;18a,18b) which are oriented to direct the air flow entering the tunnel in one direction or the other. The valve comprises an adjustable baffle (17;19) adapted to shut off access to the channels (16a,16b;18a,18b) either wholly or partly. In the treatment method of the invention, the air flow (F;F?) entering the tunnel is divided into two unequal components (F1, F2; F1?, F2?) directed towards opposite ends of the tunnel.

Abstract: A fluid-driven apparatus continuously feeds fabric in open-width form. The apparatus is associated in combination with a tumbler processing the fabric. The apparatus includes a tubular duct, with a substantially rectangular transversal cross section, has boundary walls which delimit an internal cavity inside the duct. A manifold supplies gaseous fluid into the duct through an opening formed in the top or bottom wall of the duct. Ports for the fluid extend in a direction longitudinal to the duct, into and out of the cavity. The manifold abuts the opening to divide the duct into two distinct stretches delimited by the manifold and by the ports. The manifold includes a diverter for selectively directing the fluid towards one of the stretches of the duct. A portion of one of the duct stretches is divergent in shape, with a transversal cross section increasing from the manifold to the respective end port.

Abstract: A machine and a method for treating fabrics, comprise in combination a step of inducing substantially vertical vibrations in a quantity of fabric in the form of a substantially compact mass and a simultaneous step of drying the rest of the fabric in opened-out form.
