Z-Press for CLT cross layers at Stora Enso put into operation

Excellent performance and quality!

Despite Covid-19 and the consequencing difficult conditions, a complete CLT cross-layer system with a new Z-press CL was assembled on time and on schedule at Stora Enso in Ybbs. This system is specially designed for the quick and easy production of cross-layer panels. There are very few interfaces, as the system was mostly implemented by Ledinek.

The newly developed Z-press CL is also used for assembly bonding of cross-layer laminations using hotmelt glue and optionally also with white glue. Multiple widths or single-layer panels are manufactured from laminations glued on the narrow side. Such pre-glued single-layer panels are indispensable for the advanced and high-performance cross laminated timber production and thus introduce a new quality of CLT production.

Company: Stora Enso
Location: Ybbs / Austria
Project manager CLT-QL Production: Peter Strasser, Kevin Hödl
Plant manager Standort Ybbs: Werner Hatteier
Operator CLT-QL Produktion: 1
Production capacity: 40 - 140 m³ / shift

The project was monitored and followed by Stora Enso by Peter Strasser and Kevin Hödl. Together with Ledinek team led by the project managers Milan Mendas and Patrick Kornherr, the interfaces, commissioning and performance tests were carried out duly and on time. Both companies are justifiably proud of their project teams and their achievements. Ledinek thanks for the innovative opportunity and for the very good cooperation.

Congratulations to both teams!
