Whether it's because bottles are unstable or in other to optimize flexibility and speed in line format changes, some lines transport bottles inside pucks (also called godets).
The POSIPUCKS unscrabler perfectly inserts bottles into pucks and can also utilize any of POSIMAT's format change systems: manual or automatic.
The pucks enter empty from the end of the line and all of them exit the unscrambler with a bottle inside. No puck is sent to the filling line without a bottle.
