Optimizing Sensor Placement and Roller Position in Displacement Guides

This episode is part of the 'Web Guiding Fundamentals' webinar series, focusing on the importance of sensor placement and the location of entry and exit rollers to maintain a 90-degree wrap for optimal control and stability of a displacement guide system. The video discusses how to position sensors close to the exit roller, the effects of web speed on sensor placement, and the consequences of incorrect installation, including bending and oversteering. By following these guidelines, you can ensure smooth operation and avoid unintended consequences like web breaks.
