  • Publication number: 20200109514
    Abstract: A method for a treatment of a product web which is transported in an advance direction includes guiding the product web through a treatment gap which is formed by a first treatment roll being arranged in a first working position and a contour tool, providing a second roll, moving the second roll into a second working position in which the second roll forms a second treatment gap with the counter tool, and moving the first treatment roll into a first parked position in which the first treatment roll does not form a treatment gap with the counter tool.

  • Patent number: 10385503
    Abstract: An iron includes a soleplate, a heating body including a lower face in thermal contact with the soleplate and an upper face at which a vaporization chamber is provided, and a system for injecting water into the chamber including two injection openings that simultaneously inject water onto two separate evaporation areas of a bottom wall of the chamber when the soleplate is arranged horizontally. The chamber is bordered laterally by a side wall extending from the bottom wall to a closing cover attached to the heating body, the side wall including a passage establishing communication between the chamber and a steam distribution circuit leading to a steam outlet opening provided in the soleplate. The passage is provided at one longitudinal end of the chamber. The chamber includes a separation wall extending from the two evaporation areas to the passage to provide a partition between the two evaporation areas.

  • Patent number: 10344847
    Abstract: A cooling arrangement (1) is provided for cooling a gearbox (2) that has a housing (20) on which at least one temperature-critical component is mounted. The cooling arrangement has a gearbox-ventilating device (4) arranged fixedly on the body to adjoin the gearbox (2) and configured to supply the gearbox (2) with cooling air. The gearbox-ventilating device (4) has a first air duct (6) with an air inlet opening (60), via which cooling air can flow into the first air duct (6), and an air outlet opening (62) from which cooling air can flow out of the first air duct (6). A cooling air-channeling means (7) is connected to the first air duct (6) and designed to guide the cooling air flowing out of the air outlet opening (62) and directly onto the temperature-critical component of the gearbox (2).

  • Patent number: 8522462
    Abstract: Piezoelectric pump for a household electric appliance having a moving wall interposed between a first casing element defining a pumping chamber with the moving wall, and a second casing element applying pressure to the periphery of the moving wall in order to hold the latter in position. The moving wall has an exterior face in contact with a piezoelectric actuator designed to cause the moving wall to move so as to bring about a periodic variation in the volume of the pumping chamber under the action of the piezoelectric actuator wherein the first casing element and the second casing element are held together under stress by an elastic clip, the elastic clip applying a pressure that tends to compress the first casing element onto the second casing element.
