A first number of stacks of objects is placed on a first number of carriers on a first side of the frame and a second number of stacks are removed from a second number of carriers on a second side of the frame where the first number can be greater than, less than or equal to the first number. The carriers clamp onto a continuously moving drive belt in a manner that allow the drive belt to slip through the carrier clamps when motion of the carriers is obstructed.
