    摘要: In an apparatus for the application of a liquid or pasty substance onto a traveling material web, notably of paper or cardboard, a doctor bar serving the metering of the applied substance is composed of at least two bar segments strung together in the longitudinal direction of the doctor bar and fixedly joined to one another. Possible thereby, in the manufacture of the doctor bar, is an easier handling and a better compliance with accuracy requirements.

    摘要: A method and apparatus for coating a traveling layer of material, in particular paper and/or cardboard. An applicator implement applies a predetermined and proper amount of a liquid or pasty medium onto an outer surface of a first rotating applicator roller which in turn transfers the liquid or pasty medium onto a first side of the moving layer of material just as it is moving through a press nip. A second layer of coating medium is applied indirectly with a second applicator implement onto an outer surface of a second rotating applicator roller from where it is transferred onto the previously coated side of the moving material layer while the first coat of coating medium is still wet.

    摘要: Disclosed are a process of and an apparatus for producing paper webs coated on both sides, in particular so-called LWC-papers, in a paper making machine. Firstly, one side of the paper web (1) is coated in a first coating station (8) and then dried. Subsequently, the other side of the paper web (1) is coated in a second coating station (25) and then dried. Each coating station (8, 25) includes an application role (10), an opposing roll (11) and an application unit (13) arranged on the application roll for indirectly coating the paper web. The metering of the coating mass on the application roll (10) takes place by means of a smooth roll doctor. The coated paper web (1) is calendered by means of an on-line calendering unit (60).

    摘要: The invention concerns a coating system with at least one web support roll and at least one corresponding metering roll coordinated with it and having a grooved surface essentially in peripheral direction or in the form of a threading, for metering the coating substance in the gap existing between the web support roll and the metering rolls. A groove forming or groove truing system can be infed in the operation of the coating system can be infed onto the metering rolls.

    摘要: An apparatus for direct or indirect application of a liquid or pasty medium onto a traveling material web includes at least one rotatable backing roll wrapped in part by the material web and supporting a side of the material web near the backing roll. The backing roll surface and the material web form a cuneiformly tapering entrance gore and an exit gore. At least one applicator opposes the backing roll and coats a side of the material web away from the backing roll with the medium, and/or further treats the coated material web side. A boundary layer stripper is arranged, in relation to the direction of rotation of the backing roll, before the applicator. The boundary layer stripper removes an air boundary layer entrained by the backing roll and/or the material web. The air boundary layer stripper is arranged in the entrance gore between the backing roll surface and the side of the material web near the backing roll.
