Material web e.g. paper web, guiding device, has housing with guiding surface, where gas outlets are arranged in guiding surface, and compressed gas is discharged via gas blowing openings that are arranged outside of guiding surface

摘要

#CMT# #/CMT# The device has a housing (7) with a guiding surface (8), where gas outlets (9) are arranged in the guiding surface. The gas outlets are connected with a gas pressure producing device e.g. blower. The housing has gas blowing openings (16, 17), which are arranged outside the guiding surface, where compressed gas is discharged through the gas blowing openings. The gas outlets and the gas blowing openings are in connection with the same gas pressure producing device. #CMT# : #/CMT# An independent claim is also included for an arrangement with a coating mechanism for a material web and a device for contactless guiding of the material web. #CMT#USE : #/CMT# Used for contactless guiding of a material web e.g. paper web or cardboard web. #CMT#ADVANTAGE : #/CMT# The gas blowing openings of the housing are arranged outside of the guiding surface, where the compressed gas is discharged through the openings, thus ensuring the quality of the surface of the material web in a simple manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of an arrangement with a coating device for a material web and a device for contactless guiding of the web. 2 : Material web 7 : Housing 8 : Guiding surface 9 : Gas outlets 16, 17 : Gas blowing openings.
