Corrugated Media
Transfer of Starch and Glue
Today, corrugated packaging is seen everywhere. Corrugated media is light and at the same time stable. Its secret is the corrugations that lend the product very high stability. At the same time, the air-filled chambers created by the corrugations ensure its unique cushioning function. It is both appealing to the eye and structural.
The cardboard is produced by combining different layers of paper by means of starch that binds the board together. Fluted sheets and flat liner boards are glued to each other in several layers, so that the final result is a single, dual, or triple wall corrugated cardboard. The core manufacturing piece is the corrugator. This very long machine consists of several individual units which are separately and independently controlled. Thus there are many flute profiles as well. Inside, the individual layers of paper are heated, moistened, laminated and then dried. Afterwards the desired format is cut to size.
ABEL deliver a reliable and energy efficient electromechanical diaphragm pump for an 24/7 operating process. Due to the excellent performance, energy costs can be reduced significantly. Another feature of the EM is the nil-flow control which automatically allows to stop the pump under pressure and therefore increase process safety.
Advantages of ABEL Pumps
Production of Corrugated Cardboard in Europe
An important component in manufacturing corrugated cardboard is the glue that is used. Our customer uses glue that Electric diaphragm pumps made by ABEL are used to transport the glue at a temperature of 35 – 40°C to and from the flute lamination machine as well as for continuous circulation. These pumps are electrically driven, dual effective diaphragm pumps with mechanical membrane deflection. Unlike the previously used compressed air diaphragm pumps, they generate considerably less noise; the irritating ventilating noise when the control valve is triggered does not occur. In addition, the energy balance is impressive.
Complete Conversion to electric Pumps
The ABEL EM pumps offer high efficiency and consume far less energy than pumps operated with compressed air. Cost savings are especially significant during continuous operation. Energy conservation was one of the main reasons our customer selected these pumps. All installed pumps are frequency-regulated. Being true positive displacement pumps, EM pumps are very tolerant of changing degrees of viscosity of the pumped glue and therefore can deliver constant and consistent flow independent of counterpressure. The first ABEL EM pump was delivered and commissioned in the summer of 2011. Since then, another 7 identical EM pumps have been added. All of the glue pumps in the corrugated cardboard factory have been completely switched from compressed air drive to electric drive. The EM pumps provide reliability, efficiency and low operating costs to our customer. That’s the ABEL difference.
