Austrian paper manufacturer Laakirchen Papier AG has commissioned technology supplier Voith to implement the comprehensive rebuild of PM 11 at its Laakirchen site.
The company, which is part of the Heinzel Group, is converting the plant from the production of graphic papers to containerboard. The planned start-up of the rebuilt production line is in the second quarter of 2024, increasing the production volume from 350,000 tpy of SC papers to 500,000 tpy of containerboard per year.
Thanks to a customer-specific stabilisation and drying concept, the rebuilt machine will be able to produce papers with a basis weights from 70 g at high production speeds.
Numerous components of the machine will be relocated and the web guiding system adapted to the new requirements. Special focus is being placed on optimising the machine's press. To avoid web breaks, Voith will also adjust the transition from the press to the dryer section and supply a new sizer for sizing and a new energy-efficient after-dryer section. The necessary changes to the control system, including programming, will be carried out by installing Voith's automation systems. The scope of the order also includes two winders.
