Munksjö Caieiras Ltda, Brazil, operates ropeless tail threading from Runtech Systems
The PM7 paper machine at Munksjö Caieiras, located in São Paulo, Brazil, has recently undergone a major modernization as part of the company’s ExpanDecor project, the largest investment in Munksjö’s history in Latin America. As part of this upgrade, Runtech Systems supplied a ropeless tail threading system featuring Runshooter technology, along with detailed engineering and start-up support for the dryer section. With this modernization, Caieiras aimed to achieve smoother and faster tail threading as well as enhanced operator safety.
“Our tail threading systems are installed end-to-end in the dryer section. The start-up wasn’t without its challenges—after such a long shutdown and so many upgrades, that’s to be expected. We worked closely with the customer and other partners to overcome the hurdles together and learned a lot along the way. It was a valuable experience, and we’re proud to see our system running smoothly. From the beginning, the customer was satisfied with the system. The first attempt took less than one minute to get the tail through the entire dryer section,” said Janne Helle, Installation Technician at Runtech Systems.
Runtech Systems’ ropeless tail threading technology provides significant advantages. It greatly improves operator safety and reduces tail threading time during web breaks by up to 80%, directly contributing to higher production efficiency. In many cases, the technology also enables mills to increase machine speed—something that would not be feasible with manual tail threading without compromising operator safety. Furthermore, the automated process allows operators to focus on other essential tasks. Combined, these benefits result in a rapid payback period for the investment.
