The invention relates to an arrangement to strip unwanted matter from belt bands (2) in conveyor belt installations in the region of a driving and/or direction-changing roller (3) of the belt band, comprising a systems support (4) which is attached to a supporting structure for the belt band and on which at least one stripping member (5) is arranged. Each stripping member comprising a scraper blade (17; 48) which is attached to a support (16; 49), which scraper blade, in the ready-to-operate position, abuts against the belt band (2) in a peeling fashion. The stripping member comprises a torsion spring joint (25) on which the blade support is guided in a spring-loaded manner and so as to pivot about a horizontal axis such that, when the scraper blade encounters obstacles which rigidly adhere to the belt band, it can pivot away and subsequently again pivot back into the working position on the belt band. In this regard, the blade support (16; 49) is pivotally supported by a pivot bearing (20a; 50) having a limited pivot angle, such that the scraper blade (17; 48) which abuts against the belt band (2) can adjust to changes in inclination of the belt band (2) in the immediate contact region of the scraper blade (17; 48) by pivoting automatically. The torsion spring joint (25) is attached to a plug-in means (26) which is arranged in a holding means (27a, 27b) which is attached to the systems support (4). The longitudinal axis (28) of the plug-in means (26) intersects the belt band (2) at a point which, in the direction of rotation of the roller (3), is disposed upstream of the contact line (S) of the scraper blade (17; 48).
