Abstract: A tunnel-type rotary drum tumble dryer includes a cabinet (1) with a loading door (2) and an unloading door (3) on opposite sides, and a drum (4) arranged inside the cabinet (1) for rotating with respect to a horizontal or inclined geometric axis (E). The drum (4) has a revolution wall (5) around the axis (E), and end openings (5a, 5b) at opposite ends facing said loading and unloading doors (2, 3). The tumble dryer also includes an air circulator that includes an air inlet (8) facing one of the end openings (5a, 5b) of the drum (4) and an air outlet (9) adjacent to the other end opening (5a, 5b) of the drum (4) for creating an axial flow of drying air inside and from one end to another of the drum (4) through the clothing tumbling inside the drum (4).

Abstract: The industrial tumble dryer comprises a casing (1) enclosing a drum (2) to contain the clothes to be dried by means of drying air introduced into it, a low-pressure chamber (3) to extract drying air from the drum (2) and a filtering device (4) interposed in the low-pressure chamber (3). The filtering device (4) comprises a filtering element (5), means to detach fuzz from said filtering element (5) and a build-up enclosure (6) to collect the detached fuzz. In the casing (1) there is an opening (7) communicated with the build-up enclosure (6) and configured to receive a suction nozzle (8a) of an external suction device (8) to remove the fluff from the build-up enclosure (6) through suction without the need to remove the filtering element (5) or to access it.

Abstract: An ironing roller includes a first annular chamber in communication with an inlet and an outlet arranged to rotate about a longitudinal axis, where the first annular chamber forms a passage through which a heat carrying fluid heated by heating device located inside the ironing roller circulates, a circuit external to the annular chamber being arranged to lead the heat carrying fluid from the outlet to the inlet of the chamber. A second annular chamber adjacent and coaxial to the first annular chamber is provided, the two annular chambers being intercommunicated for the circulation of the heat carrying fluid from one of the annular chambers to the other, and where one of the annular chambers carries out a heat uptake function and the other one carries out a heat transfer function.

Abstract: The invention relates to a locking device for the door of an apparatus comprising a rotary drum, and to a latch for one such device. The inventive device comprises a latch articulated to a moving leaf of the door, and a control box attached to a fixed frame of the door and configured to receive and immobilize the tip of the latch into a passage provided therein. The aforementioned tip acts primarily as a control tip. The latch comprises at least one second tip acting as a coupling tip which is spaced apart from the control tip and which is configured such that it can be coupled in a retaining stop that is attached to the fixed frame of the door in a position spaced apart from the passage in the control box.

Abstract: The machine has a drum with a perforated wall capable of receiving a load of clothes, a motor for rotating the drum at variable speeds, and a spraying device capable of introducing liquid into the drum. The method includes performing an impregnation with an amount of liquid by several spraying steps for spraying the liquid on the load of clothes while the drum rotates at a medium rotational speed sufficient to keep the load of clothes stationary with respect to the rotating drum but insufficient to extract liquid out of the load of clothes by the centrifugal force generated, and performing, between every two of the spraying steps, a tumbling step for tumbling the load of clothes at a low rotational speed less than 1 G. After the impregnation, a centrifugation at a high rotational speed is performed.

Abstract: A support structure for a clothes washing machine is provided. The support structure includes a frame supporting a washing tub rigidly attached thereto, and a drum arranged inside the tub to rotate with respect to a substantially horizontal or slightly tilted axis, the frame having supports for installing a motor for driving the drum. The frame is made up of resistant elements including metallic plate elements shaped by cutting and folding, assembled and joined together by screw or deformation attachment devices, or by welding. The frame can be linked by a suspension system to a base constructed in a similar way, or the frame can be rigidly joined to the base.

Abstract: A roller ironing machine for articles of clothing includes a heated ironing roller supported, guided and rotated in a frame, a floating pressure roller parallel to and in contact with the ironing roller and endless belts mounted to satellite rollers to cover part of the ironing roller. Additionally, axial journals belonging to the floating pressure roller rest against inclined planes which are fixed to the frame such as to form an angle in relation to a plane that is tangent to the ironing roller and the floating pressure roller on the line of mutual contact. The journals rest against the planes with a force that includes a normal component derived from the weight of the roller, thereby producing a greater ironing force than the weight of the roller owing to the wedge effect provided by the opposing directions of rotation of the ironing roller and the floating pressure roller.

Abstract: A support structure for a clothes washing machine is provided. The support structure comprises a frame that includes attachment means for rigidly coupling a washing tub inside which there is mounted a drum arranged to rotate with respect to an axis that is substantially horizontal, or slightly tilted with respect to a horizontal direction, and support means for installing a motor for driving the drum.

Abstract: Said floating group comprises: a drum (20) aligned with a center line (M) which rotates within a wrapping bin (10) driven by a motor (32), and when it rotates it creates, by an effect of masses unbalance, an actual rotation axis (N) different from said center line (M); a counterweigh (40) of mass mCE associated to a front part of the bin (10) and a counterweigh (42) of mass mCT associated to a front part of the drum (20), where the ratio [mCT/(mCE+mCT)]×100≧55, said mass mCT either a given magnitude centered with said center line (M) or a very lower magnitude and in the form of one or more fluid rings (60), the stresses the floating group sustains resulting substantially reduced, it being for it made in a light construction.
