The E+L Complete Paper Alignment System includes the TensionMaster Bridge Brake System to ensure optimum control of machine direction board shape, which is a key requirement for maximum conversion productivity. The TensionMaster features a closed loop tension control system to ensure that target tension values are achieved, regardless of influencing factors such as a change of bridge volume or a speed change. The TensionMaster can be configured with a pneumatic brake or a servo drive to ensure that various process and product factors which create excessive pre-tension do not impact the quality of the finished board. The servo drive also functions as a threading aid to assist the operators when threading up the corrugator.
