Process for making a fibrous water soluble product

A method of manufacturing a fibrous water soluble product comprising particles, comprising:

• a) providing a first continuous water soluble fibrous substrate comprising a first side and moving in a first direction;
• b) providing a discretizing unit comprising one or more pockets comprising an opening and a rotor;
• c) providing a stator;
• d) providing a continuous feed of first particles through a plane of the stator to at least one of the one or more pockets of the discretizing unit through the pocket opening at least partially filling the at least one of the one or more pockets;
• e) delivering the first particles from the pocket through the pocket opening and through an opening in the stator onto a portion of the first side of the first continuous water soluble fibrous substrate, by gravity, without the discretizing unit contacting the continuous water soluble fibrous substrate, such that the final portion of the particles exiting the stator outlet have a trajectory that is not predominantly downward, but is in the machine direction of the first continuous water soluble fibrous substrate;
• and
• f) at least partially covering the first side of the first continuous water soluble fibrous substrate with a second continuous water soluble fibrous substrate;
• g) cutting the first continuous water soluble fibrous substrate and the second continuous water soluble fibrous substrate using a die.
