METHOD AND APPARATUS FOR PRODUCING A CAPSULE, AND THE RELATED CAPSULE

摘要

A method for producing an element (1 ) of a capsule, the capsule being intended to contain a product having at least one component that can be extracted by means of an extraction fluid, comprises the step of obtaining at least one preparatory zone (6) intended to define, during use of the capsule, a passage for the extraction fluid, so that the extraction fluid can pass through the capsule in order to extract said component. The preparatory zone (6) is obtained by means of a cutting operation carried out before the capsule is filled with the product and after the capsule element (1 ) has been formed. The cutting operation is carried out by means of a blade element (28; 228; 328; 428; 528; 628; 728; 828).
