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 Paper Schmidt is the first rebound hammer designed specifically for the testing of the roll profile. Extensive field tests carried out at major manufacturers and converters in the US and Europe has consistently shown that it provides previously unachievable accuracy and repeatability of the roll profile.
The instrument is fully compliant with the TAPPI T834 om-07 standard used in North America to regulate the test of the paper roll profile and it delivers instantly all of the key parameters required for assessing the quality the of paper roll. In addition to this the Paper Schmidt has an extended lifetime to cope with the heavy demands of the paper industry and dedicated tools, such as pre-defined tolerances that make assessing a roll profile a simple matter.
The Paper Schmidt meets the customers' needs for a quick and reliable test of the roll profile.
The Equotip 550 Leeb U is the direct successor of the highly appreciated Parotester. It enables the user to quickly and precisely diagnose roll imperfections, hardness inconsistencies and uneven winding, thereby preventing problems for printing and converting operations. Portable and lightweight, the Equotip 550 Leeb U is perfect for roll hardness testing in the warehouse or on the production floor, providing an immediate visual assessment of the hardness profile.
The new generation Equotip Touchscreen Unit offers an elaborate interface designed by industry experts for increased efficiency and an exceptional user experience. The enhanced software provides an interactive wizard, automatic verification processes, personalization options and custom report functions. The Touchscreen Unit is compatible with existing Parotester impact devices. The full color display facilitates the best possible measuring experience and analysis of the measured data. The specially designed housing optimizes the on-site usage of the device in harsh environments.
