Abstract: An improved stripping device effectively strips filter cake from the belt of a rotary belt filter while avoiding damage to the belt. A cross bar type body extends transversely to the filter belt and scrapers for the belt are fixed to the body and directed towards the belt. The cross bar type body is part of a tilting device which pivots about a transverse shaft arranged parallel to the cross bar type. The body is subjected to force in the form of a weight whose center of gravity is between the transverse shaft and the belt and which acts against the direction of movement of the belt. A acts against the direction of the force.
