    摘要: An arrangement for application of liquids, such as a coating unit for a printing press, with a liquid supply above the metering gap formed between a metering roller and an applicator roller interacting therewith, a partition designed to damp vibrations dividing the liquid supply along the length of the rollers in order to compensate for turbulence, resonance and irregular air occlusions as far as the metering gap and to prepare uniform quantities of liquid. For this purpose baffle plates at right angles to the rollers have edges adapted to conform to the curvature of the roller surfaces to define a communicating gap with the roller surfaces, said baffle plates being arranged in a fixed position just inboard of the ends of the two rollers and formed as a unit with the partition defining a constant communicating gap with applicator roller, the partition having regularly arranged communicating channels in the form of holes, preferably a first row near the continuous bottom edge and a second row above the first one.

    摘要: To provide for compact construction with minimum components, and permit application of two prime prints and one verso print, a chain transport system (9, 14, 15) is carried over the rubber blanket cylinder (7) applying the second prime printing. The sheet is fed between two blanket cylinders (3, 5) applying, respectively, verso and a first prime printing, held by grippers on the verso blanket cylinder and transferred to grippers (15) on the chain for transfer to a delivery station (10) or a further printing station (FIG. 2: 13), for example by use of a further transport drum (12) for proper positioning of the sheet.

    摘要: The invention relates to a method of preparing a varnish blanket. Instead of a proof being used for pre-location of required varnish-free zones on a blanket for blanked-out in-line varnishing in rotary presses, the zones required not to be varnished are transferred by means of a reference copy, and after physico-chemical pretreatment adapted to the surface properties of the blanket, to a blanket stuck to a support plate. In addition to polyvinyl alcohol copying layers or coatings sensitized by bichromate, wipe-on copying layers sensitized by diazo salts are suitable, a positive or negative original being copied by direct contact in known manner onto a blanket thus pretreated. The zones required not to be varnished can therefore be preformed by cutting out the top layer of the blanket.
