Variable Crown Roll Rebuilds

The experienced roll refurbishing specialists

Roll refurbishment services — including complete rebuild and regrinding — have been PRG's only business since 1970. It is not a sideline. We have continued to refine our technologies and craftsmanship to provide the industry's finest rebuilding services for all makes and models of variable crown rolls. The result of a PRG-rebuilt variable crown roll is that it makes quality product longer, providing improved operating efficiencies and longer intervals between rebuilds.

PRG's facilities are dedicated specifically to rebuilding and testing these specialized rolls. Among the many advantages of this dedication is a state-of-the-art dynamic test station where roll performance can be measured at operating speed and temperature.

To provide our customers with on-machine trouble-shooting assistance, we have experienced field service technicians who are available to assist you in the field with start-up operation and the analysis of your roll problem.
