A Basic Guide to Web Guiding

Your web’s path may not be where you want it. One remedy is to find and correct the original source of the path upset. This might be as simple as moving the unwinding roll over sideways a bit. More often, it is not quite that easy. Another remedy is to change the path of the web using an active guide. Under ideal conditions, you might achieve hairsbreadth (0.005-in. / 125-micron) accuracies. Those ideals include requiring only modest path correction rates and distances, clean-cut and straight web edges, as well as good sensors, good guide mechanicals and good controls.
