摘要： An applicator for direct or indirect application of a liquid or pasty coating medium onto a traveling material web includes a metering system with a metering slot configured as a nozzle and formed between an approach-side lip and a departure-side lip. The applicator also includes, disposed opposite the nozzle, a traveling countersurface on which the coating medium issuing out of the metering slot is to be applied. The exit of the metering slot is followed by a transfer blade for the coating medium, arranged on the approach-side lip. The transfer blade has its length, with respect to the countersurface, selected such that the transfer blade in its operating position contacts the countersurface. The transfer blade passes the coating medium along its departure-side surface from the exit of the metering slot onto the countersurface.

摘要： The invention is directed to an applicator for coating a traveling fiber web with a coating mixture. The applicator includes a backing roll having a shell surface for carrying the web, and a nozzle for feeding the coating mixture. The applicator includes a support beam; a nozzle which is integral with or connected to the support beam; and a doctor bar carried by the support beam. The doctor bar has a guide surface. The guide surface and the backing roll define a nip for producing a hydrodynamic pressure. The guide surface approaching the shell surface of the backing roll extends to an exit edge at a location nearest the backing roll. A device is provided for flexibly backing the doctor bar on the support beam.

摘要： This invention relates to the treatment of substrates with fluidized material in repetitive patterns during application cycles. The treatment patterns made with this invention can be altered by changing machine operating parameters. The patterns of fluidized material are applied to substrates using an applicator drum. Machined in the outer surface of the applicator drum are a plurality of slots filled with deformable material. The deformable material extends to a position in each slot just short of the outside diameter of the applicator drum, leaving a cavity in each slot. These cavities are filled with slurry in a slurry applicator unit. A compression drum mounted within the hollow interior of the applicator drum uses compression tips to displace the deformable material in each slot in succession beyond the periphery of applicator drum at a position adjacent to the substrate, causing the slurry in the cavity to be applied to the substrate.
