Roll Profile Measurment

Roll Profile Hardness Test Equipment will record a comparative measure of hardness for rolls of cardboard, paper or film and present the data as a diagram of roll hardness. Common technologies are impact based, including rebound hammer, Leeb U, or Impact hammer deceleration.

Test Systems

Out of round rolls and other defects such as corrugations may be caused by non-uniform roll hardness profiles will cause lost production when feeding those roles.

The use of Roll Profile hardness test equipment enables the user to quickly and precisely diagnose roll imperfections, hardness inconsistencies and uneven winding, thereby preventing problems for printing and converting operations.
