A machine for inspecting objects such as containers comprises a conveyor, a rejector for removing rejected objects from the conveyor, an inspection device for inspecting the objects upstream of the rejector and for producing a continuous stream of input data including a tracking signal, and a control for randomly evaluating the input data stream and converting it into an output data stream for operating the rejector at a predetermined number of cycles after a transition in the input data indicates that an object should be rejected. Thus two data streams that are not related real-time are operated on so that the input stream can be processed real time vis-a-vis the output stream. Both streams are clocked by the same encoder, and a random tracking signal is imposed on both streams. A reject signal on the input stream can accordingly be placed at the correct location on the output stream.
