Breast Roll & Fourdrinier Wire Showers

Pick Constant Flow

The breast roll supports the fourdrinier wire at the headbox end of the paper machine. Both the breast roll and machine wire tend to accumulate stock fiber. A series of showers serve to clean fiber buildup, improving drainage and runability of the paper machine. Accurately controlled water temperature is crucial to this application.
