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.

Abstract: This relates to the manufacturing of reinforced materials, such as reinforced cellular materials or reinforced textiles, for example. Reinforcement is achieved by including a textile semi-finished product into the material to be reinforced, by providing the semi-finished product at the rear side of the material in a zigzag or wave-like manner and then pulling the semi-finished product through the material by a plurality of needles. Thus, the manufacturing process may be performed in a time saving manner.
