Whether it’s a spare part for your existing WTI system or you need a custom web guide for your new application, Precision Process can assist you with your WTI Web Guide needs. WTI Web Guides and components are used in a variety of applications: Business Forms Press, Commercial Offset & Rotogravure Printing, Package Printing and Flexible Packaging, as well as Custom Designed Web Guiding Systems.
A WTI Web Guide will maintain the alignment accuracy of your substrate into your manufacturing process thereby increasing production and reducing waste. An electronic feedback system monitors and corrects edge position 4 times faster than pneumatic systems. Accuracy improves from ±015" to ±003" or better. Maintenance decreases in the absence of fluids, filters, etc.
