A mail weighing and sorting machine directs mail in seriatim from a weighing station along segmented track portions of a main feed track. As each piece of mail is weighed a weight signal is delivered to a control circuit which is operative to cause a selected track segment to intercept the corresponding piece of mail as it travels along the main feed track. The control circuit includes a comparator which produces weight category signals from various stages thereof depending upon the weight of each piece of mail. Each computer output stage is connected to an associated delivery circuit. Each delivery circuit includes means for gating its various weight category signals to a corresponding actuator control, but some of the gated signals are delayed in a primary delay device which provides outputs to both the corresponding actuator control and an AND gate for gating a second weight category signal to a secondary delay device in the event the first delay device is already delaying a first weight category signal.
