Transforming Art into Science

In blade side load systems, overall system mass and harmonics play a significant role at higher speeds. Accuracy of the side loading is only as accurate as the active component (spring, air cylinder, electronic motor, etc.). Blade side load systems that allow the blade to tilt over the edge of the lower anvil blade will compromise slit quality unless dished blades are used. With a dished blade, the inner part of the blade is pushed in from the outer blade edge. The result is a blade that has an appearance similar to a dish or dinner plate. Recommended side force settings are: 2 to 3 lbs. for tissue and thin plastic film; 3 to 4 lbs. for communication papers; 3 to 5 lbs. for packaging laminates; 2 to 5 lbs. for non-wovens; 4 to 8 lbs. for light boards; and 6 to 10 lbs. for heavy boards.
