Abstract: An apparatus and a method for shrinking continuous textile substrates are described. The apparatus comprises: a first motorized roller; a second motorized roller; an endlessly wound belt for conveying and supporting the textile substrate; a pre-tensioning means for applying a predetermined longitudinal tension to the belt and a means for guiding the belt. According to the invention, the belt is substantially elastically deformable longitudinally. The pre-tensioning means comprises an idle roller and the guiding means comprises a rotating drum for guiding the belt along a length between the second motorized roller and the first motorized roller. The textile substrate is conveyed arranged between the belt and the rotating drum.

Abstract: A continuously operating apparatus for the wet heat treatment of a continuous textile substrate advancing in a predetermined direction is described, the apparatus comprising: a unit for hydro-thermal treatment of the textile substrate, comprising a chamber able to contain a heated treatment fluid; a first group for conveying the textile substrate into the hydro-thermal treatment unit; and a second group for conveying the textile substrate out of the hydro-thermal treatment unit, characterized in that it also comprises pressure sealing groups, said pressure sealing groups being associated with said substrate conveying groups so as to close said chamber in a substantially sealed manner so that the treatment fluid may be pressurized to a pressure higher than atmospheric pressure.

Abstract: An apparatus for heatsetting a knitted fabric in tubular form comprises flat expansion means which extend the tubular fabric in substantially flattened form, with two superimposed surfaces, and cause said fabric to assume a preselected width, conveying means which feed said flattened tubular fabric, heatsetting elements which form at least one air flow, at a preselected temperature, and guiding rods associated with the conveying elements and the heatsetting elements; the rods being capable of supporting internally the flattened tubular fabric along its side edges, owing to the action of the heatsetting elements, while keeping the side edges extended, leaving the two superimposed surfaces free to be passed through by the air flow and keeping the width of the flattened tubular fabric unchanged.

Abstract: An expanding device (11) for tubular knitted fabrics (34) comprising a translating unit (12) on which two magnets (17), 17'), two pairs of traction wheels (15, 16, 15', 16') and two lateral expanders (22, 22') are fastened by a plurality of supporting plates (13, 13'), and on which two metal plates or, preferably, two magnets (23, 23') are attached closely facing the magnets (17, 17'); where the lateral expanders (22, 22') are fitted on swiveling pins with four pairs of sliding rollers (26-29, 26'-29') associated with four pairs of guiding belts (30-33, 30'-33') engaged with the traction wheels (15, 16, 15', 16'), so that the lateral expanders (22, 22') become rigidly connected to the translating unit (12) thanks to the force of attraction between the facing magnets (17, 17', 23, 23'); where the lateral expanders (22, 22') each hold two bipolar magnets (24, 25, 24', 25'), and four pairs of magnets or electromagnets (18-21, 18'-21') are fastened to the supporting plates (13, 13').

Abstract: An apparatus for the wet surface treatment (i.e., sueding) of continuous textile materials, including an outer casing provided with an entry region and an exit region, a wet treatment unit containing treatment water and into which a continuous textile material to be treated is passed and at least one rotating fluffing (i.e., sueding) roller against which the continuous textile material is made to slide, the at least one fluffing roller being at least partly immersed in the treatment water contained in the wet treatment unit.

Abstract: A profiled cylinder for teaseling and/or fluffing machines of the type having a generally cylindrical outer peripheral surface and provided at its ends with support hubs for its rotation, in which the radially outer peripheral surface has a particular profile caused by a plurality of variously arranged geometrical forms or surface portions disposed for abraiding contact with a fabric which is to be treated by passage through the machine.

Abstract: A method for surface treatment of wet fabric webs in a finishing machine containing an external housing, provided with an inlet zone and an outlet zone, through which a fabric web to be treated is run, and at least one grinder roller rotatably arranged inside it, against which the fabric web is caused to slide. The surface treatment of the fabric is carried out by using abrasive diamond material as the grinding material for the grinder roller.

Abstract: An apparatus for continuous steaming and dimensional stabilization of continuous fabric webs includes a steaming tunnel (11) through which a conveyor belt (12) runs, which supports and conveys a continuous fabric to be treated (13), the steaming tunnel (11) being provided with an inlet opening (14), an outlet opening (15) and a steam delivering device (16), in which apparatus the inlet opening (14) and the outlet opening (15) are both arranged under the bottom tunnel portion and inside the tunnel, opposite to at least one of the openings a temperature sensor (23) is provided which modulates the emission of steam from the steam delivering device (16). Furthermore, a method is accomplished for the steaming and dimensional stabilization of continuous fabric webs, method which is constituted by the treatment of fabric webs in an air-free atmosphere of saturated steam.

Abstract: An apparatus for continuous fabric decatizing, comprising a cylindrical drum, the outer lateral surface of which is covered with a sleeve of textile material about which the fabric is fed, the cylindrical drum and the sleeve being at least partially covered and embraced externally by an endless under-piece of textile material arranged so that at least one portion of the under-piece maintains the fabric in contact with the sleeve, the rotary drum being perforated and supported on a fixed coaxial inner cylinder having a diameter less than the drum and being maintained spaced therefrom by radial wall extensions which are positioned within the portion of the lateral surface of the drum in which the fabric is maintained in contact with the sleeve, and are connected together to define a chamber containing an atmosphere of steam under pressure fed from the outside of the fixed cylinder, and a subsequent forced suction treatment chamber.

Abstract: An apparatus for causing the shrinking of a cloth, comprising a revolving drum, an endless-loop belt wound around said drum, a return roller which causes said endless belt to adhere to said drum, a flexible sheet partially winding around the belt and the return roller and entering a portion between said drum and said belt wound around the drum, and guide means for guiding the cloth to be processed, in which apparatus the ratio of the diameter of the return roller to the thickness of the belt is such as to cause an improved compacting effect on the cloth.
