Products (7, 8, 9) are advanced on at least one conveyor (1) towards a final position or stop (11) at a reception unit (3). In the area of the free end portion (2) of the conveyor (1) there is a restraining member (6) displaceable in a vertical direction towards the product flow, the member (6) being adapted such that in a stepwise advancement of the products by the conveyor (1) it can arrest or clamp products (7) of the right length and height, whereas faulty products (8) are removed with the aid of a lowerable hatch (4). The conveyor (1), hatch (4) and the products on the conveyor are arranged for displacement a short distance opposite to the advancing direction at the rejection operation, the product or products in the final position on the reception unit (3) being no longer urged by the following products and are removed, e.g. for further conveying to a packaging station. |
