<p>A cigarette filter assembly machine (1) wherein a rolling unit (8) is defined by a rolling drum (34) and a guide drum (21) coaxial with each other and connected to each other in angularly-fixed, axially-sliding manner; and wherein the rolling drum (34) has a number of suction rollers (54) rotated, with respect to the rolling drum (34), by respective independent drive units (49; 88); the guide drum (21) has a number of semicylindrical cavities (23), each coaxial, and defining a relative rolling channel (69), with a relative suction roller (54); the suction rollers receive, with a first spacing (P1), relative groups (4) of component parts (5, 6, 7) of a relative double cigarette (11); and each drive unit (49; 88) rotates the relative suction roller (54) to roll the relative group (4) inside the relative rolling channel (69) and to extract a relative double cigarette (11) from the relative rolling channel (69), and reverses the relative suction roller (54) to release the relative double cigarette (11) with a second spacing (P2) smaller than the first spacing (P1). <IMAGE></p> |
