The MM840 FanFold is the logical further development of proven Müller Martini technology. As a modern retrofit system, it transforms a Müller Martini 840 into a powerful, highly flexible FanFold system for demanding production processes.
With the ability to efficiently combine two paper webs and process them into high-quality continuous stacks, the MM840 FanFold opens up new production potential. Whether high-stack or low-stack, switching is conveniently performed by key switch. An integrated flexographic printing unit and a powerful gluing station enable single- or double-layer web processing – with no conversion effort.
Two transverse and two longitudinal perforation stations, precise web tension and web edge controllers, and a linear-meter counter with mark applicator guarantee maximum precision and quality. Thanks to a retrofit based on a Müller Martini 840, the MM840 FanFold combines a robust base design with state-of-the-art technology and excellent cost-effectiveness.
Technical Highlights:
- Web width up to 840 mm
- Speed up to 600 m/min
- High-stack and low-stack operation conveniently switchable by key switch
- Unwind diameter 200-1500 mm
- Stack height up to 1000 mm
