The corrugated industry utilizes rolls in numerous functions including feeding, hold down, coating and printing. Each of these applications has their unique parameters that must be met. These include heat and chemical resistance, release, hardness and modulus. An effective roll covering must possess characteristics which match the requirements of the specific application. Urethane roll coverings for corrugated applications typically must exhibit high coefficient of friction properties, abrasion, and heat and ozone resistance.

Universal Urethane makes conventional feed rolls at several different durometers to fit the needs of our customer’s process. We also make dual durometer feed rolls that have a hard top layer with a softer bottom layer for less corrugated crush.

Rolls have been installed in both the glue station and cut-off knife areas with outstanding results.
