An extraction unit (10) for extracting cartridges (1a; 1b) of two different heights (ha;hb) comprises a cartridge receiving seat (14,20) which is delimited by a first part (20, 21, 22) and a second part (14,15,16) that are relatively movable between a cartridge extraction position and a cartridge loading and/or ejection position The first delimiting part (20,21,22) has a locking device (30), a first cavity part (21) and a second cavity part (22). The cavity parts (21,22) are relatively movable into first and second cavity positions for defining a cartridge cavity (21') having selectively: a first depth (Ha) for receiving a cartridge (la) having a first height (ha); and a second depth (Hb) greater than said first depth (Ha) for receiving a cartridge (lb) having a second height (hb) greater than said first height (ha). The locking device (30) is configured to lock the first and second cavity parts (21,22) into at least one of the first and second cavity positions when the first and second delimiting parts (14,20) are in the cartridge loading and/or ejection position or close thereto. |
