Operating Principle
Pressurisation of the rubber sleeve alters the angles within parallelogram modules, thereby providing precise and uniform blade pressure on the belt surface. The system automatically compensates for scraper blade wear. The constant blade/belt angle and even blade/belt pressure over the full belt width are other unique features of the design.
