Latest Patents

Roisum holds a patent titled "Method and apparatus for quantitatively evaluating roll hardness." This invention offers a systematic approach to testing the hardness of various rolled materials, enabling operators to obtain reliable data across different testing conditions. The apparatus is designed to function similarly to a traditional backtender's stick, allowing users to strike the roll at designated points to determine hardness levels. Integral to this device is an accelerometer, which provides critical signals regarding the energy of the impact and the peak deceleration of the striker. These signals are processed to generate a roll hardness measure, which can be correlated to a widely used Rho scale, ensuring consistency regardless of the force applied by the operator.
