Abstract
Apparatus (1) for removing detected tramp material (TM) in a flow of material (M) moving along a primary flow path (P). The tramp material is deflected into one of two deflection paths (P1, P2) which are located of opposite sides of the material flow path. A scoop (29) is responsive to the detection of tramp material to deflect it into one of the deflection paths. The scoop is transported over rails (45, 47) between the deflection paths and across the primary flow path by a carriage (43) driven by a penumatic cylinder and rope and pulley unit (65). An actuator unit (91) repositions the scoop after each traversal of the flow path so it can deflect tramp material on its next traverse of the primary flow path.
