ABSTRACT:
A device for transferring and verifying batches of cigarettes, placed transversely with respect to the direction in which they move forward and in superposed layers. Miniaturized reflection photocells in a number identical to the number of layers composing the cigarette batches are provided for checking cigarette ends. As each batch passes, each of the elements emits a signal in response to the performed check. These signals, converted into logical form by a first circuit block, pass into a second circuit block which, synchronized with cyclic signals indicative of the checking elements examining the central areas of the ends of the cigarettes, constitutes means for operating an ejector device.
