ABSTRACT:
A conveyor system for aligning objects includes three sequentially arranged conveyor belts. The first belt has a velocity v.sub.1 and delivers the objects to the second belt. The second belt runs intermittently, having a mean velocity at least equal to v.sub.1 and delivers the objects to the third belt. The third belt runs continuously at a velocity of at least 2v.sub.1. An alignment rail over the third belt is lowered to align the objects, and is periodically raised to let them pass. A periodically acting thrusting device over the third belt may be provided for urging rows of the objects closer together. A vertically movable product holder may be provided at the end of the second belt to inhibit passage of objects to the third belt except during determined intervals. A further alignment rail may be provided on the third belt after the thrusting device for realigning the objects, if necessary.
