The FlexDoc water scraper ensures optimal and targeted dewatering in the press sleeve. Cleanliness in the press section is thus increased, and the total storage volume in the nip is utilized.
FlexDoc consists of an outside water scraper and an inside pneumatic support strip. During operation, the inside support strip moves toward a defined limit stop and is thus placed against the press sleeve. The support strip stabilizes the sleeve in this area and ensures a more even running of the sleeve. The flexible water scraper is then applied with a predefined force. It ensures that the entire open volume of the press sleeve is available to absorb the water in the nip, thereby achieving the highest level of dewatering performance.
FlexDoc is successfully used with NipcoFlex rolls as well as with shoe presses from other manufacturers.
