Abstract: An application device and method for coating a fibrous material web, such as a paper web, a web of packaging material, or a web of cardboard. The application device has an application nozzle for applying a coating medium, in particular a starch solution, to a moving surface, and the application nozzle has an outlet gap that produces a film of coating medium or a curtain of coating medium. A device is provided for varying the application amount and the variation is based on a strength variable.

Abstract: An application device and method for coating a fibrous material web, in particular a paper, packaging or board web. The application device has an application nozzle for applying a coating medium, in particular a starch solution, to a moving surface and the application nozzle has an outlet gap which extends in the width direction of the application nozzle for producing a film of coating medium or a curtain of coating medium. The application nozzle has a gap width across its width direction that may be varied by profiling devices.

Abstract: A method for producing and/or processing a nonwoven glass fabric web includes thermally drying the nonwoven glass fabric web via infrared radiation from an infrared radiation dryer. A specific power density of at least 153 kW/m2 is applied by the infrared radiation dryer to the surface of the nonwoven glass fabric web facing toward the infrared radiation dryer. After the irradiation by the infrared radiation dryer, the nonwoven glass fabric web has a temperature of at least 40° C. and at most 105° C. on its surface facing toward the infrared radiation dryer.

Abstract: The invention relates to a method for detecting soiling of clothing providing a contact surface and a cavity volume in a machine for producing and/or treating a material web, in particular a fibrous web such as for example, paper, cardboard or tissue web, on which the soiling is detected and evaluated using a detection and evaluation unit. A detection and evaluation unit categorizes the soiling according to the soiling, distinguishing at least between soiling on the contact surface of the clothing and soiling within the clothing.
