Abstract: A sorting machine can include an output bin that includes a transport belt to transport a delivery item (e.g., a letter) from a distribution belt at a first speed. The output bin can include a braking roller to reduce the speed of the delivery item by operating at a second tangential speed that is slower than the first speed. The output bin can also include an auger assembly to apply a force to move at least the trailing portion of the item in a manner that clears the path to the braking roller for additional delivery items. The output bin can also include a bumper pad to stop the delivery item, where the delivery item is stopped against the bumper pad after being slowed down by contact with the braking roller. The slowed speed causes the delivery item to come to rest approximately in alignment with additional delivery items.
