This type of machine has a disc that rotates, and arms that guide the rotated bottles or other packaging containers. The arms guide the containers to the outside of the disc, and then the containers are guided off the unscrambler, usually onto a conveyor. This ensures that the containers will be in a single file line. In some cases, containers are already upright when they go into the disc unscrambler. In other cases, containers are randomly assorted when they enter the unscrambler, and they are deployed on their side, using a secondary orienter to set them upright.
