| 发明名称 | Deviation device for a web of film | ||
| 摘要 | A deviation device for a film web has at least one deviation element, which operatively interacts with the film web at the point of deviation of the film web and guides the film web on an air cushion. The deviation element can be rotated and has a drive device, which sets the deviation element into rotation so that the peripheral speed of the deviation element differs from the transport speed of the film web. | ||

| 主权项 | 1. A deviation device for a film web of a film-producing or film-processing plant, comprising: at least one roller that operatively interacts with the film web at a point of deviation of the film web and guides the film web on an air cushion, the roller being axially rotatable about an axis thereof and including a drive device that sets the roller into rotation so that a peripheral speed of the roller differs from a transport speed of the film web so as to create the air cushion, a direction of rotation (A) of the roller being opposite to a transport direction (B) of the film web at the point of deviation, that the peripheral speed of the roller being greater than 30 m/s, and a maximum roughness depth of an outer surface of the roller being between 0.5 and 2 micrometers. | ||
