An apparatus for weighing a first item in a series of items traveling on a conveyor in which a first item is downstream of a second item in the series of items. The apparatus may comprise: (1) a scale; (2) an item repositioning mechanism that is adapted to move (e.g., slide) the first item from the conveyor into weighing engagement with the scale; and (3) a braking mechanism that is adapted to limit the forward progress of the second item while the item repositioning mechanism moves the first item from the conveyor into weighing engagement with the scale, and to thereby prevent the second item from passing the first item while the first item is in weighing engagement with the scale. In other embodiments, the braking mechanism may release to allow the second item to pass the first item while the first item is in weighing engagement with the scale.
