Claim 3:
4. A method for producing unit dose articles, comprising:
providing a forming surface having a plurality of cavities, continuously movable in a machine direction,
feeding a first continuous water-soluble film on said forming surface at a first position,
retaining said first continuous water-soluble film on said forming surface as it moves in said machine direction and forming a plurality of recesses in said first continuous water-soluble film by keeping said first continuous water-soluble film adherent to said plurality of cavities,
delivering dosed quantities of fluid products into said plurality of recesses,
applying a second continuous water-soluble film on said first water-soluble film at a second position located downstream of the first position and joining said first and second water-soluble films to each other by water-sealing around said plurality of recesses so as to enclose said dosed quantities of fluid composition between said first continuous water-soluble film and said second continuous water-soluble film,
wherein water sealing is carried out by wetting 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 the wetting is performed by a wet sponge touching on said first water-soluble film over said forming surface upstream of said second position.
