Machine and method for making capsules for beverages

A machine for making capsules that contain a product for preparing a beverage, the machine comprising:

• a forming station for forming at least a casing of a capsule in a sheet that is made of thermoformable plastic material and is movable along an advancing direction, where the casing has a cavity and projects from a first side of the sheet, and the cavity is open on a second side of the sheet;
• a shearing station provided with a punch and a die that oppose each other and are movable to approach each other, during a cutting operation, for cutting the sheet so as to separate the capsule along an edge of the capsule and creating a through opening in the sheet;
• and
• a filling station for dosing the product inside the cavity,
• wherein said punch during the cutting operation is movable so as to abut the first side of the sheet, cut the sheet in cooperation with said die, and then lift and detach the capsule from the sheet,
• wherein said punch and said die in a detaching operation are movable away from each other for placing the capsule on the second side of the sheet, and
• wherein the through opening is created in the sheet by separating the capsule, the through opening having a passage section that is smaller than external dimensions of the edge in order to allow the sheet to support and move the capsule along the advancing direction.
