Web edge control in the processing of paper, paperboard and cardboard

Description

During the manufacture and processing of paper, paperboard and corrugated cardboard, the web edges must be controlled appropriately depending on the corrective purpose. Previous control systems act directly on the material. They are, as a result, very interference-prone due to the extreme conditions that are present there, such as dirt and high temperatures. An alternative solution is therefore sought.

Solution

The LES 36 light section sensor is used. The analog value of the edge recorded by the light section sensor is used for web edge control. The device can be mounted at a distance of up to 800 mm from the material, i.e., outside of the zone that is exposed to extreme stress; it is not negatively impacted by the dirt and high temperatures on the material.
