An apparatus and method for training a troughing conveyor belt are provided. The apparatus includes a training roller enclosing a concentric shaft. The training roller is rotatably connected to the shaft. In addition, the training roller is pivotable relative to the shaft about a pivot axis that is transverse the longitudinal axis of the shaft. The training roller engages the conveyor belt so that the conveyor belt rotates the training roller. When the conveyor belt is properly aligned, the force of the belt against the training roller is equally distributed on both sides of the pivot axis of the training roller. When the belt becomes misaligned, the training roller pivots in response to the unequal force of the conveyor belt on opposite sides of the pivot axis. The belt then travels down the pivoted roller, thereby realigning the belt. The shaft is rotatable between two positions. Rotating the shaft also rotates the pivot axis of the training roller. A pair of friction rings frictionally couples the training roller with the shaft so that reversing the direction of the conveyor belt that is in contact with the training roller rotates the shaft between the first and second positions, thereby rotating the pivot axis. Accordingly, reversing the direction of the conveyor belt rotates the pivot axis of the device so that the device continues to train the conveyor belt while the belt travels in the reverse direction.
