Machine and method for making segmented cigarette filters (2; 2a, 2b), according to which segments (3, 4) of several types are combined in various manners to obtain given successions of filter groups (16) of different compositions, applying to the segments (3, 4) given speeds and phases during their push-advancement along a combining device (15), which is provided with an inlet (44) for each type of segment (3; 4) and with an outlet (41) for the filter groups (16) and presents a succession of annular tracks (37-40) suitable to be followed in part by the segments (3, 4) and in part by the filter groups (16) and extending on a flat horizontal plate (17) for supporting and resting, in use, the segments (3, 4) and the filter groups (16); an initial distribution of the filter groups (16) at the outlet (41) being changed by imparting a controlled braking to the filter groups (16) during their transfer from the combining device (15) to a forming beam (55) of a continuous worm (60). |
