ABSTRACT:
An apparatus and method for selectively removing articles, such as cigarettes, from a transfer conveyor system in which the transfer of the selected articles to a receiver conveyor from a transfer conveyor is rejected within a transfer zone. Vacuum suction retaining articles on the transfer conveyor is blocked in the transfer zone as articles pass to the receiver conveyor. Transfer of selected articles is rejected by application of an air pulse responsive to a reject signal. The selected articles are returned to the transfer conveyor, from which they are removed.
