Adjusting for the correct tension during the slitter operation is critical for tension sensitive materials. The closed-loop rewind tension control option gives operators the optimum level of control over the rewinding process. This option is particularly helpful for converters running tension-sensitive materials such as light gauge, extensible films.
Load cells are used to take tension readings for closed-loop rewind tension control. The slitter control system automatically adjusts the air pressure in the rewind shafts. This adjusts the rewind tension to match the load cell readings. This maintains the desired tension based on the base tension setting, taper tension setting and current roll diameter.
Deacro’s slitter touch screen allows real-time monitoring of the rewinding process throughout the build up of the roll(s). A load cell roller is used to take incremental tension readings throughout the winding process. The data can then be compiled and output in a graph or chart format.
