Battenfeld-Cincinnati USA (formerly American Maplan Corp.), McPherson, Kans., has developed a highly efficient roll-stack concept to complement its line of single-screw extruders for sheet. With the new Multi-Touch roll-stack system, which makes its debut at this month’s NPE2012 show in Orlando, the sheet passes through more than just the usual two polishing nips. The first two rolls have a larger diameter for low deflection; the following rolls are smaller, with quicker cooling-side changes, in order to produce a uniform, stress-free sheet. Nip pressure between the rolls ensures that no air will be trapped between the rolls and the sheet, even at higher line speeds. This, in turn, leads to an optimal heat transmission and quick cooling for higher transparency and gloss, particularly for PP.

Due to its modular design, the Multi-Touch roll stack can be adapted for a desired throughput by adding more rolls. A conventional post-cooling unit ensures a low temperature for coiling.
