Method of manufacturing a detergent water-soluble pouch

A continuous method of manufacturing a detergent water-soluble pouch, wherein the pouch comprises a first compartment that is enclosed by a first water-soluble film and a second water-soluble film, wherein the first water-soluble film is sealed to the second water-soluble film, wherein the first compartment comprises detergent composition, wherein the detergent composition comprises first detergent particles and optionally second detergent ingredients,

• wherein the method comprises the steps of:
• (a) providing the first water-soluble film moving in a first direction, and forming a cavity in the first water-soluble film;
• (b) providing a feed of first detergent particles to a rotating discretizing element comprising at least one pocket, wherein the rotating discretizing element rotates through a rotating arc, wherein the rotating arc has a first portion and a second portion, wherein the first detergent particles are dosed into the pocket when the pocket is in a position within the first portion of the rotating arc, to form a loaded pocket;
• (c) rotating the loaded pocket of the rotating discretizing element from the first portion of the rotating arc to the second portion of the rotating arc,
• (d) dosing the first detergent particles from the loaded pocket to the cavity of the first water-soluble film when the loaded pocket is in a position within the second portion of the rotating arc, to form a loaded cavity;
• (e) dosing second detergent ingredients to the cavity of the first water-soluble film;
• (f) providing the second water-soluble film moving in the first direction, and placing the second water-soluble film over the cavity of the first water-soluble film and contacting the second water-soluble film to the first water-soluble film;
• (g) sealing the first water-soluble film to the second water-soluble film and entrapping the first detergent particles and optionally the second detergent ingredients to form the first compartment;
• and
• (h) repeating steps (a) to (g);
• wherein the rotating discretizing element rotates at variable speeds,
• wherein a rotating speed of the rotating discretizing element when the pocket is not in a position within the first portion of the rotating arc is controlled so that the dosing of the first detergent particles into the cavity during step (d) is matched to the frequency at which the cavity passes through the position from which it can be filled with first detergent particles.
