1. A machine for producing unit dose articles, comprising:
a forming unit including a forming surface having a plurality of cavities, continuously movable in a machine direction,
first feeding means for feeding a first continuous water-soluble film on said forming surface at a first position,
a dosing apparatus located downstream of said first position and configured for dispensing dosed quantities of at least one fluid composition into said plurality of cavities;
second feeding means for feeding a second continuous water-soluble film on said forming surface at a second position located downstream of said dosing apparatus and joining said second continuous water-soluble film onto said first continuous water-soluble film so as to enclose said dosed quantities of fluid composition between said first continuous water-soluble film and said second continuous water-soluble film, and
a wetting unit for wetting a surface of one of said first continuous water-soluble film and said second continuous water-soluble film upstream of said second position,
wherein said wetting unit is configured to wet only surface areas of said one of said first continuous water-soluble film and said second continuous water-soluble film which are to be joined to the other of said first continuous water-soluble film and said second continuous water-soluble film, and
wherein said wetting unit comprises a wet roller contacting on said first water-soluble film over said forming surface upstream of said dosing apparatus.
