Application for Pinch Roller Machine Set-up and Alignment
The I-Scan® is an excellent tool for measuring nip
profiles, force or pressure variations along a roll axis. The system measures and displays in real-time
the static forces in a pinch roll nip. For many large machines, nip contact is adjusted by setting hydraulic
pressure at contact units located on the ends of the rolls. In the absense of measurements, the
relationship between hydraulic pressure and nip force is assumed to be linear. Drag in the linkage and other
sources of hysterisis are not quantified. With I-Scan, nip force and width can be directly measured at
locations along the axis and at various hydraulic pressures. The effectiveness of crowning and differences
in pressures and contact width along the length of the roll can be documented. These measurements reduce
machine set-up time and minimize product scrap saving your company time and money.
Tekscan’s patented,
thin-film sensors are available in different shapes and pressure ranges, are reusable, and provide accurate
pressure data. With the help of our highly qualified sales and engineering support team, each system can be
configured to meet your specific needs.
