AV-Spreader Roll Overview

The WINertia™ AV Spreader Roll with Reverse Crown Profile gets the wrinkles out!

The WINertia™ AV Spreader Roll is created by machining a taper at the center of the WINertia AV Idler for a “Reverse Crown” profile. The tapered dead shaft roller creates a larger diameter at the outer edge and a smaller diameter at the roll center. This design creates a greater surface speed at the ends of the roll. The result is a web tension distribution that spreads the web from the center out.

The WINertia™ AV Spreader Roll is the customer-preferred solution for its exceptional traction, performance and value
