Device for preventing wrinkle formation in material web, has bristle bundles deformed by running material web when bristle bundles contact brush wheels at contact surfaces for producing lateral force in outward direction of material web

摘要

The device has brush wheels (3) rotating diagonal to a running direction (5) of a material web (1), where the brush wheels apply lateral force on the material web. The brush wheels engage in an edge area of the material web. Bristle bundles are deformed by the running material web when the bristle bundles contact the brush wheels at contact surfaces for producing the lateral force in an outward direction of the material web, where the material web runs between the brush wheels at the contact surfaces.
