Slitting theory: How to produce a good roll

This comprehensive course packs a lot of learning into a little time. With both lecture and lab time, you’ll get the last information from the industry experts. Lecture topics include the following subjects:

• Fracture Mechanics: Learn the science of how things come apart at a molecular level. This topic covers the mechanics of web separations using different slitting technology. You’ll also explore the characteristics and properties of the different materials you may be slitting.

• Methods of Slitting: There’s more than one way to make the cut. We’ll take a look at several of the most common methods and machinery, including: Shear, Crush, Razor, Water Jet, Laser, and Die Cutting.

• Controlling the Variables: Learn how dwelling in the details, such as blade sharpness, cant angle, down force, overlap and a variety of other variables can help you optimize performance and minimize waste when shear or crush slitting.

• Cause and Effect: This section of the lecture delves into the holistic theory of slitting – see how factors like tension, guiding and web spreading have an affect on the big picture.

Additional topics to be covered include:

• Material Properties
• Blade Profiles
• Safety
• Defects on Roll Slitting
• Operator Accessibility
