Film & Paper-roll Hardness

• Out of round rolls and other defects such as corrugations caused by non-uniform roll hardness profiles are a major cause of lost production for both producers and converters alike. A reliable measurement of the roll hardness profile is of critical importance in deciding whether a roll is good or bad. Proceq’s instruments give the production staff the support they need to quickly and reliably test the roll hardness and to interpret the results as efficiently as possible. It enables the user to quickly and precisely diagnose roll imperfections, hardness inconsistencies and uneven winding, thereby preventing problems for printing and converting operations.
