Atromaxx felt. Accordingly, all further felts were delivered in the same design. With the mill completely converted to New- Tech felts, machine productivity continued to increase. The values determined one year after the change of type were impressive across the board: Steam savings: Close to 70 per cent
Electricity consumption: Reduced by two thirds Productivity: Eleven hours additional production time due to reduced breaks Savings: €200,000 per year
Modern production technologies in combination As the recognised specialist in non-woven and multiaxial clothing, Heimbach has gone on to successfully further develop these proven production techniques. So Atrojet combines woven modules with a multiaxial non-woven structure. This new technology has now also entered the market,
January/February 2020
proving its strengths on a daily basis.
Multiaxial non-woven press felts Advantages and gains. • Excellent start-up and drainage behaviour • High uniformity of paper profiles • Minimised hydraulic disturbances in the paper
• High residual strengths for given surface dimensions
• Very robust (e.g. very resistant to intensive treatment from HP showers)
Case study 3 Successful as a set of 3 The operator of a high speed LWC machine (1,800 m/min) runs with three New-Tech generation designs: Atrojet in the pick-up
position, Atrocross+ in the first press and Atromaxx in the second press. Atrojet started up with excellent dewatering values. Atrocross+, the crossless felt with intermediate batt, worked without suction boxes. Nip dewatering occurred immediately and start- up speed could be increased by 100 m/min. The so-called ‘cost triangle’ could be eliminated right from the off.
