ABSTRACT:
A conveyor handling system is described for separating into discrete batches a stream of articles arriving at regular intervals. The system includes two endless belts extending between first and second locations and arranged to be driven at the same predetermined speed in the same sense. A movable carriage between the first and second locations constrains the intermediate portions of the said endless belts so that one belt forms the upper run of an intermediate portion of the conveyor system and the other belt forms the upper run of the conveyor system both upstream and downstream of the intermediate portion. The carriage is arranged to be reciprocated at a speed greater than the predetermined speed between a first position where the intermediate portion lies adjacent a loading position and a second position where the upstream portion of the conveyor lies adjacent the loading position. When the carriage performs its forward stroke from the first to the second position, the one belt is locked to the carriage so as to be accelerated. When the carriage performs its return stroke the belt is allowed to move freely relative to the carriage and therefore the one belt moves at its predetermined speed.
