Increasing accuracy of web tension systems

A combination of EBU brakes and EKU hysteresis clutches managed by ZF's ERM controllers has proven to have the accuracy and reliability to successfully replace DC drive based tension control systems in three high precision presses at Day International (UK). The company manufactures rubber sheeting used for producing newspapers and banknotes in high-speed printing presses - a process which primarily involves attaching a layer of rubber to a fabric backing. After considering a manual clutch system to replace increasingly high maintenance inverters, the company's engineers rejected the idea due to risks of contamination from dust particles, a problem conveniently avoided by the magnetic non-contact operation of the hysteresis units. After twelve months of faultless use, Day International fitted a similar system to accurately control a three-way web of materials as they were joined and fed through an adhesive curing oven. After continued success, the third main operation was also upgraded which involved feeding the sheets extremely slowly through the equipment that grinds the surfaces of the cured rubber sheets flat to tolerances of 10 microns. By using such a versatile system engineers could reduce wastage and downtime, but also standardise spares, easily expand the systems to control new webs and integrate the complete set up with their current PLC.
