  • B. Piezo drives use, since they are particularly fast and do not tend to swing.
  • the surface quality of the rolls can not be permanently increased for cost reasons. Furthermore, there are production and transport processes of band-shaped materials, in which it would be desirable to avoid contact of the material with the rollers in principle. In some applications, it is possible to use instead of rolling tubular deflecting units, in whose surface air nozzles are arranged. However, the use of such tubular baffles remains limited to applications with lower accuracy requirements, since these systems operated with compressed air are difficult to control and tend to oscillate when z. For example, the belt-like material to be transported has regular openings through which the compressed air passes. Also by web tension fluctuations it can come to swinging in the area of the air nozzles. It is equally possible that are caused by pressure fluctuations in the compressed air supply web tension fluctuations.
  • the apparatus comprises a directional deflecting unit with a curved deflecting surface 1 over which the endless material passes, its direction being changed.
  • At least one vibration generator is arranged on the deflection unit so that the vibration generator excites the deflection unit to oscillate. With regard to frequency and amplitude, these oscillations are selected in such a way that sound pressure waves arise at the curved deflection surface and keep the passing endless material at a curved deflection surface 1 at a distance.

Abstract

L'invention concerne un dispositif pour guider des matériaux plats sans fin en forme de feuilles, de tôles minces et autres, sur des dispositifs de déflexion, sur lesquels ces feuilles et tôles minces subissent un changement de direction. Le matériau sans fin passe sur une unité de déviation ayant une surface de déviation courbe, et sa direction y est modifiée; au moins un générateur de vibrations (10) est disposé sur l'unité de déviation (11), de telle sorte que le générateur de vibrations entraîne l'unité de déviation (11) à vibrer et qu'il se produise sur la surface de déviation courbe 1 des ondes de pression sonores qui retiennent le matériau sans fin en mouvement à distance de la surface de déviation courbe 1.
