battenfeld-cincinnati USA (formerly American Maplan Corp.) will showcase its extrusion of high quality sheet for packaging (booth 911). In addition, the company will also introduce its new multi-touch roll stack. battenfeld-cincinnati’s 75-mm (3-inch) single screw extruder series has more than 150 lines installed worldwide. The extruders offer energy savings of up to 30%, shorter start-up and reversal times. Due to short residence times, higher material melt quality can be realized. Output ranges from 400-2000 kg/hr depending on material and application, with higher outputs possible by adapting motor power and screw speeds.

battenfeld-cincinnati multi-touch roll stackDue to short residence times, higher material melt quality can be realized. Output ranges from 400-2000 kg/hr depending on material and application, with higher outputs possible by adapting motor power and screw speeds. In North America, most extruders are in the middle output range and used for direct feeding of thermoforming machines, the company stated. Common materials processed are PP, PS and A-PET, but the battenfeld-cincinnati extruder series can also be used for ABS, PLA and other polymers.

battenfeld-cincinnati will introduce the new multi-touch roll stack system at NPE. Here, the sheet passes through a number of polishing nips. The first two rolls have a larger diameter for low deflection; the following rolls are smaller in order to enable the production of an even, stress-free sheet with quicker cooling side changes. The 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 surface gloss, particularly in PP applications.

Due to its modular design, the multi-touch roll stack can be adapted to the expected throughput by adding more rolls. A conventional post-cooling unit is installed to ensure a low temperature for coiling. The first multi-touch roll stack has been in use in the field for a few months.
