Process for cutting a water-soluble web

A process for cutting a water-soluble web comprising the steps of:

• a. providing an anvil;
• b. providing a rotating knife roll, wherein said rotating knife roll comprises between one and ten knives mounted on said rotating knife roll, and wherein each individual knife comprises a cutting edge wherein said cutting edge extends outwards from said rotating knife roll;
• c. providing a water-soluble web, wherein the water-soluble web comprises:
• i. flat areas wherein the flat areas comprise a first side and a second side, wherein the first side contacts the anvil and the knife contacts the second side during cutting, and wherein the flat areas have a thickness of between 50 microns and 400 microns;
• and
• ii. filled capsules formed within the water-soluble web, wherein the capsules are connected to and separated from one another by the flat areas and wherein the capsules protrude outwards from the second side;
• and wherein said water-soluble web is moving in a machine direction at a constant speed V1;
• d. passing said water-soluble web between said anvil and said rotating knife roll, wherein the first side of the water-soluble web is in contact with the anvil;
• e. cutting said water-soluble web with said knives as said water-soluble web passes between said anvil and said rotating knife roll;
• wherein, the rotating knife roll rotates at variable speeds, and wherein a single complete rotation of the rotating knife roll consists of a number of cutting cycles, wherein the number of cutting cycles is equal to the number of knives on the rotating knife roll and
• wherein during a single cutting cycle, said rotating knife roll rotates at least at a first rotational speed R1 and a second rotational speed R2;
• wherein R1 equals V1, and R2 is at least 15% faster than R1 and wherein the rotating knife roll is rotating at R1 when each individual knife cuts said water-soluble web in a cross-machine direction, and wherein each cut of the water-soluble web is performed by only one of the knives at a time.
