Auma KraussMaffei’s Auma rotary presses can produce composite roofing sheets and floor coverings from plastics and fabric reinforcement and also are suited for continuous rubber sheet vulcanization. Additionally, the continuously operating presses can weld, emboss and laminate plastic film and sheet. In contrast to discontinuously operating platen presses, Auma machines ensure constant temperature, pressure and residence times, preventing product quality variations, unevenness or transition marks. Appropriate for processing materials 0.5mm to 20mm thick, the presses feature a heating drum, three reversing rolls and a pressure belt that is wrapped around a large part of the drum circumference and presses the material against the heating drum.
What’s new? Four new machines with heating drum diameters measuring 2 feet, 3.3 feet, 4.9 feet and 6.6 feet. All four sizes are available in three working widths, ranging from 4.3 feet to 8.2 feet. Two belt designs are available: steel belts that are suited for a wide variety of applications; and rubberized steel mesh belts for use with materials that are very thin or extremely pressure-sensitive. The new machines have a standard operating temperature range from 176 to 428 degrees Fahrenheit; the series also includes a special version designed for temperatures as high as 644 degrees Fahrenheit. Data recording, quality management and connection to the interfaces of upstream and downstream equipment are standard features.
Benefits Enhanced productivity and easy maintenance. The versatile machines provide stable operation with long service intervals and have reasonably priced spare parts for maximum cost- effectiveness for the life of the press. Worn pressure belts can be replaced quickly because it is easy to access the heating drum and reversing rolls.
