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 test quickly and reliably the roll hardness and to interpret the results as efficiently as possible.
The PaperSchmidt is the first rebound hammer designed specifically for paper roll hardness testing.
The Parotester provides accurate and reliable evaluations of the roll hardness of foil and film where a lower impact energy is required.
