Earlier in 2025, the joint project team had the opportunity to gain a comprehensive impression of the calender and threading system during factory acceptance tests at Bellmer’s facilities in Willich, Germany. These tests confirmed the excellent functionality of the system. Shortly thereafter, installation at the Piteå mill was carried out according to plan, followed by on-time commissioning and start-up.
