Offset printing press - Import export

The POWERTACK electrostatic ribbon tacking system is used in the folders of heatset web offset and publication gravure printing presses. Their task is to electrostatically block the incoming paper ribbons to prevent dog ears. This is a standard feature for new presses and available for retrofitting on all common heatset presses of the world. High voltage generators generate positive and negative high voltage which is passed on to the charging bars mounted in the folder. The positive and negative bars are arranged opposite each other. The ribbons pass between them. The resulting force causes the paper ribbons to attract each other, the air in between is displaced and the ribbons are pressed against each other. As a result, the press can run at a higher speed with better folder accuracy.

In the past, Eltex Remoistening systems have guaranteed high quality printed products mainly on fastrunning and wide machines. The WEBMOISTER 3000 ensures high-quality products in all heatset web offset machines. Using a new nozzle concept, both lighter and heavier grammages can be remoistened at all web speeds with ultimate precision and homogeneity. The new pneumatic atomizing nozzles are capable of applying smallest water quantities without developing waste water. The modular structure of the nozzle bar allows the WEBMOISTER 3000 to remoisten paper webs in widths of as much as 3 meters. In heatset web offset printing, paper loses moisture during drying. The WEBMOISTER 3000 remoistening system increases the water content in the paper after drying, returning to the level required and thus guarantees high quality in all heatset web offset products.
