Abstract: The device for applying a liquid to pasty application medium onto a machine (1) for the production and/or conversion of moving paper-, cardboard- or other fibrous-material web (3), comprises curtain application nozzles (4) arranged above the fibrous-material web for applying a layer of medium, and a sliding plate. The curtain application nozzle is spatially apart from the fibrous-material web. The application nozzle is fixed at a carrier construction (5). The application nozzle is arranged to the collecting grooves (6a, 6b) present above the fibrous-material web. The device for applying a liquid to pasty application medium onto a machine (1) for the production and/or conversion of moving paper-, cardboard- or other fibrous-material web (3), comprises curtain application nozzles (4) arranged above the fibrous-material web for applying a layer of medium, and a sliding plate. The curtain application nozzle is spatially apart from the fibrous-material web. The application nozzle is fixed at a carrier construction (5). The application nozzle is arranged to the collecting grooves (6a, 6b) present above the fibrous-material web for the application medium to be collected during starting and ending the coating process. The collecting groove observed from the top of the carrier construction and on the machine width is fixed at two points. The application nozzle observed on the machine width is fixed at two points. The application nozzle has several delivery nozzles. The application nozzles form a unit with one another. The unit is fixed and moved as a unit on the carrier construction. The collecting groove and the application nozzles and/or delivery nozzles are fixed to the carrier construction. The carrier construction has machine-width support beams, which are mounted to the self-carrier construction immovably at the frame of the production- and/or conversion machine on a guiding side and a driving side. One of the delivery nozzles and one of the collecting grooves are fixed at a linear guidance of the carrier construction. The collecting grooves are fixed from the top over support arms and are arranged at the self-carrier construction. The collecting grooves consist of several individual grooves viewed over the machine width. The individual grooves have an own outlet for the application medium to be collected. The sliding plate is arranged below the application nozzle and/or the delivery nozzle, is fixed at the self-carrier construction, which is intended for the application nozzle and the collecting grooves and is relocatable by a linear guidance, which is arranged on a bearing element. The bearing element is connected with the support arm for the collecting groove. The collecting grooves, the sliding plate and/or the application nozzle and/or the delivery nozzle are movably arranged to each other. An air boundary layer removal device is arranged at the bearing element by a parallel suspension and is turnable and/or tiltable from the fibrous-material web. The collecting grooves are fixed together over the parallel suspension at the carrier construction and are mutually pivotable.
