  • Patent number: 10899144
    Abstract: Printing machines are fitted with a printer assembly for application of solvent-containing printing ink onto a printing substrate. A transport device transports the printing substrate from the printer assembly to a dryer unit that has at least one infrared radiator for drying the printing substrate. The dryer unit is improved in terms of homogeneity and rapidity of the drying of solvent-containing printing ink, and in that no active cooling of the infrared radiator is required. The infrared radiator is a planar heating element made of a dielectric, emits infrared radiation when heated, and comprises a heating surface that faces the printing substrate to be dried. The infrared radiator has a contacting surface, onto which a printed conductor of a heating conductor made of an electrically conductive precious metal-containing resistor material is applied, that is connected to an adjustable current source by an electrical contact.

  • Patent number: 10322964
    Abstract: A method for producing a reflector on a reflector base made of glass is provided. According to the method, a metal-containing coating fluid is deposited on a coating surface and subjected to a burning-in treatment at a temperature below a softening temperature of the glass forming the reflector layer. Deposition of the coating fluid proceeds using a contactless method by inkjet technology. This makes it possible to deposit a reflector layer in a reproducible way and with tight tolerances having a specified layer thickness, as well as to create clean edges without a printing block or similar device. The coating fluid is moved by a print head equipped with a plurality of nozzles and is movable in a movement plane relative to the coating surface. The coating fluid is sprayed onto the coating surface by the print head under pressure and in the form of droplets emerging from the nozzles.

  • Patent number: 10112237
    Abstract: A device for drying and sintering metal-containing ink on a substrate enables homogeneous irradiation of the substrate, has compact construction, and is simple and economical to produce. Optical infrared radiators have a cylindrical radiator tube and a longitudinal axis, and emit radiation having an IR-B radiation component of at least 30% and an IR-C radiation component of at least 5% of total radiator output power. The radiators are arranged in a module with their longitudinal axes running parallel to each other and transverse to the transport direction. They thereby irradiate on the surface of the substrate an irradiation field, which is divided into a drying zone and a sintering zone arranged downstream of the drying zone in the transport direction. The drying zone is exposed to at least 15% less average irradiation density than the sintering zone along a center axis running in the transport direction.
