Top Web : Web Path Analysis

All sorts of problems arise when you have a complicated web path. You can have slippage around the roller which can scratch your web. This is conveniently captured as the Traction Safety Factor and the higher the TSF the safer you are against slippage. In the diagram roll 7 obviously has a problem. The ASF (Alignment Safety Factor) tells you how likely it is that you will have a web wrinkle or baggy edge problem due to roller misalignment.

The graphical input and output of this modeller makes it very easy to use and to interpret. The model captures many complexities of modern day machines and is a powerful aid during the machine design process and a powerful debugging tool for real-world problems.
