Paper industry

Customized roll shop upgrade solutions and services for the paper industry

RollResearch specilizes in modernization and servicing of major roll shop machinery in the paper industry. Starting the operation since early 90s’, the company has focused on upgrading roll grinding machine with its own advanced measuring technolgoy as well as other machine tools, such as roll lathes and multicore drilling machine.

 

Roll measurement technology

Taking advantage of RollResearch’s high precision 4-point measurement and grinding solutions will facilitate the papper mill to improve end product quality, process efficiency and production reliability.  4-point measurement makes 3D grinding possible which in turn will allow grinding in own bearings. This will reslut in shortening of the grinding cycle.

Our state-of-the-art 4-point measuring devices are decicated to meet the demanding requirement for roll geometry in the paper industry production. For different customer needs and production requiremnt, we have serval options for customer to choose.

The quality and efficiency of many sub-processes in the demanding sections of paper and board machines, such as coating or calendering, depend heavily on the desired roll shape. Improvement of roll geometry will enhance paper production, reduce barring and other vibrations and lengthen grinding intervals of rolls. This can be achieved through a roll grinding process that is measured and controlled by state-of-the-art and easy-to-use technology.
