End fulcrum way web guiding system is characterized by the guide roller can be swung up a certain angle in the horizontal direction of the web. Guide roller swing center is in the center of the web into the system. Therefore, the web introduction stroke (L) must be long enough, so that the web guiding mechanism can correct the web offset. The web introduction stroke (L) is determined by the multiplication of the web width and a coefficient, and the coefficient size varies depending on the material of web. Here are some commonly used web introduction stroke coefficients.
In practical application, if the single roller method is adopted, the angle between the guide roller and the web should be 90 degrees, and for the double-roller mode, the web is S-shaped through web guiding system, and the sensor is fixed on the side of the exit roller .
