ABSTRACT:
A conveyor installation has a principal line of conveyance from which products are removed at a plurality of spaced locations. Between each removal location, the principal line of conveyance comprises a haltable, two-speed accumulation conveyor and a step-advance conveyor advanceable at two different frequencies. The installation is arranged to monitor the presence of products at the loading and discharge ends of each accumulation conveyor and at the loading end of each step-advance conveyor, whereby to appropriately control the conveyors to compensate for the randomness of product distribution on the principal line of conveyance resulting from random product removal therefrom.
