  • Patent number: 11850616
    Abstract: A coating device for applying a coating agent to the surface of a workpiece. The coating device includes a frame with a workpiece receptacle, a coating agent source and a rotary unit which is rotatable in relation to the frame. The rotary unit has a pump and a plurality of spray units, with the pump on the suction side being connected to the coating agent source by a fluid-conducting rotary joint connection. The rotary unit has a pneumatic valve device, and the spray units have in each case one compressed air controlled valve for controlling the delivery of coating agent. The inlet side of the valve is connected to the compressed air source by a fluid-conducting rotary feedthrough, which simplifies the overall construction of the coating device by providing a pneumatic connection between the compressed air source and the rotary unit that is independent of the rotation angle.

  • Publication number: 20220355336
    Abstract: A UV irradiation apparatus for coating systems that coat rigid or film-like workpieces, in particular furniture parts, having a transport apparatus for transporting workpieces provided with coating material from an inlet to an outlet through the UV irradiation apparatus, a UV light source arranged above the transport apparatus that irradiates the coated workpieces with UV light in an irradiation region between the inlet and the outlet, and a reflector or cover which shields the UV light source upward. A housing covers the irradiation region and the UV light source, which generally extends above the transport apparatus. A sensor of a measuring apparatus for direct or indirect automated measurement of radiant flux of the UV light source is arranged in the housing, and the sensor is in particular fitted fixed or movably on the housing or a holder. A method for quality assurance using this UV irradiation apparatus is also provided.

  • Patent number: 9693393
    Abstract: A heated roll with a circular cylindrical casing tube 1 made from thermally conductive metal, which is closed at its end faces with caps 2, 3. One or more electric heating mats 8 are arranged inside the casing tube 1. By at least one connection pin 5, which is arranged at one cap 2, connection cables 11 are guided for supplying the heating mats 8 with electric power. Annular brushing bodies 7 are fastened at the connection pin 5 and serve for the electric contacting of the connection cables 11. A tensioning device 9, 14, 15 is arranged inside the casing tube 1, which presses the heating mats 8 permanently against the interior surface of the casing tube 1.

  • Patent number: 9023163
    Abstract: A method for laminating essentially plate-shaped work pieces with a thermally activated adhesive layer, particularly photovoltaic modules. Work pieces are inserted into a vacuum chamber having a compression element dividing the vacuum chamber in a gas tight fashion that can be raised and lowered by pressure differences. The compression element presses against the work piece which in turn presses against a heating plate which forms a lower side of the vacuum chamber, with processing heat being transferred into the work piece to soften the adhesive. The work piece is first impinged by the compression element with a slight load from approx. 2% to 10% of the defined processing load, and is simultaneously kept below the adhesive activation temperature. Thereafter, the slight load is lifted off the work piece and the work piece is heated to the activation temperature and impinged via the compression element with the processing load.

  • Publication number: 20100279059
    Abstract: A device for creating a three-dimensional molded part (30) made from fiber material using of a multiple-part mold (1, 2) whose inside (1a, 2a) determines, at least partially, the contours of the molded part. The fibers are blown into the mold by an air flow using a plurality of nozzles (4) and the air flow then escapes through openings of the mold, so that the fibers accumulate on the inside of the mold, whereupon the fibers are optionally compressed locally before they are bonded with each other through the supply of heat and are finally taken from the mold (1, 2) as a molded part (30). The blowing direction of the nozzles (4, 24, 34) can be pivoted and the pivot axes extend close to the outside of the molded part and the fibers are blown in by the nozzles (4, 24, 34) that are activated at different times.

  • Patent number: 7513287
    Abstract: A method for coating flat structural parts (2), in particular furniture fronts, with a film (3), wherein the parts lie in a pallet (1) which is turned by about 180° in a rotator after the coating process, so that the coated parts (2) joined by a common film (3) can fall out of the pallet (1) and be separated. The essential point is that a pallet (1) which can be filled on two sides is used and that the previous turning back of the pallet after the part has been removed can be omitted.

  • Patent number: 6645347
    Abstract: The invention concerns a process and a press for manufacturing laminated plastic cards, such as check guarantee cards, credit cards and the like of several films to be pressed together with each other. Moreover, operations are conducted with two compression plates which are movable relative to each other which accommodate in the compression slot the films to be pressed together with their pressure plates with the interposition of at least one compression pad. It is essential that this compression pad is held rigidly or displaceably on the press.

  • Patent number: 6210480
    Abstract: A device for wet coating, in particular printed circuit boards, with lacquer using at least one applicator roller (20, 21) and sparing at least one edge area of the printed circuit boards. The device uses a doctor blade arrangement situated between a lacquer reservoir and the printed circuit board that can move in an axial direction, one edge of which touches the applicator roller (20, 21).

  • Patent number: 5137051
    Abstract: A control device for a radiator valve comprises a housing (10, 12) including an operating, display, control and power supply portion, (14, 16, 18). Said housing comprises a cut-out (24) with which it is slipped-over a motorized drive unit (30-84). When the housing (10, 12) is removed from the drive unit, a reception housing (38) for a motor (34) and a gear unit (36) can be rotated as a hand wheel with respect to a stationary drive housing (32) flanged to the radiator valve so that the valve may be manually operated. A ring (66) being rotatable with respect to the reception housing (38) and a drive housing (32) allows balancing of tolerances and matching to radiator valves of different manufacturers.
