    摘要： An apparatus for scraping off excess coating composition from a traveling web of paper has a doctor, in the form of a flexible blade used as is or with a metering rod thereon. The doctor is fastened to a doctor supporting beam and can be pressed against the web of a paper by means of a supporting ledge which is fastened to the doctor supporting beam. The doctor supporting beam is swingably mounted at each of its two ends in a respective intermediate pivoting lever. Each intermediate lever is, in turn, pivotably mounted to a supporting bar. The pivoting axis of the intermediate levers lies as close as possible to the line of attack of the doctor on the web of paper. However, the pivoting axis of the doctor supporting beam is displaced from the pivoting axis of the intermediate levers. The end of the intermediate lever remote from its pivoting axis is connected by a pair of lift mechanisms to the doctor supporting beam. A spindle drive effects a joint swinging of the doctor supporting beam and the intermediate lever relative to both pivoting axes to maintain the doctor at a constant angle of attack relative to the web. The spindle drive and the two lift mechanisms can be coupled to each other.

    摘要： A method and apparatus are disclosed for use with a paper coater located on a backing roll of, for example, a papermaking machine. In the method, apparatus in the form of a hinged bridge is used to collect excess coating liquid from a remote doctor blade or a first coater having such blade and supply the same to a second coater. The bridge may be mounted to the doctor blade or the first coater so that it can be placed in a bridging position accommodating various angles of the doctor blade, or in a second stored position wherein it will not interfere with the operation of either coater or the doctor blade.

    摘要： An arrangement for the coating of a running cardboard, paper or the like web (1) by coating paste, whereby an excess amount of the supplied paste is removed and the supplied coating layer is levelled by means of a scraper knife (6) separately arranged after the coating position in the running direction of the web (1). The scraper knife (6) is arranged upstream, inclined relative to the running web (1) so, that the web (1) meets the knife (6) in an angle, which exceeds 90.degree., preferably considerably exceeds 90.degree..

    摘要： The invention relates to a method and an apparatus for continuously applying a uniform coating to a material web (5), in particular a paper or cardboard web, travelling over a back roller (6), to which the coating material is applied at low pressure by means of a coating roller (2) and with guidance by a guide plate (8) into the coating gap (7) formed by the back roller and the coating roller, whereupon the coating material is metered by a metering member (15) and in the region of a layer close to the material web is partly drained in order to form a barrier layer and final metering takes place in a final metering device (23) by means of a final metering member (24) with low contact pressure. Due to a three-stage method of this type and the apparatus suitable therefore, even at comparatively high material web speeds, constant good coating qualities can even be achieved with extremely low coating weights.
