A transfer unit for transferring articles having a first orientation from a first line, to a perpendicular second line along which the articles advance with a second orientation, rotated in the horizontal plane relative to the first orientation, includes a carousel having a set of pickup devices carried by rotatably supported arms driven in counter-rotation and phase relationship with the rotation direction of the carousel. Counter-rotation is obtained by idler gears meshing with a crown wheel coaxial with and fixed to the carousel and with gears acting on the arms. The gripping devices are driven in counter-rotation relative to rotation of the arms to keep their orientation constant in the horizontal plane while free ends of the arms rotate. Counter-rotation of the pickup devices is obtained by a first pinion connected by a belt to a second, smaller pinion fixed on the axis of rotation of the arm.

Transfer unit for transferring articles between two lines angularly disposed to each other

A manufacturing machine includes a group-forming unit for forming filter portion groups, each group having at least two different filter portions aligned axially and contacting at the ends; a winding unit that receives a succession of groups from the group-forming unit, winds a strip of wrapping material about the groups to form a continuous filter rod, and cuts combination filters off the rod by cyclically cutting the rod transversely; and a transfer unit that transfers the groups from the group-forming unit, in which the groups travel transversely, to the winding unit, in which the groups travel axially. The transfer unit has at least one spider that feeds the groups successively into a forming beam of the winding unit, and at least one release drum that releases the groups successively to the spider. The release drum is mounted to move between a work position and a maintenance position.

Manufacturing machine for producing combination cigarette filters

A manufacturing machine for producing tobacco industry articles, and having at least one station having a number of drums cooperating with one another to convey and process filter portions; and a supporting structure fitted to a frame and supporting the drums at the station. The station has a vertical front panel supporting at least some of the drums at the station and fixed removably to the supporting structure for replacement, together with the respective drums, when making a brand change.

Manufacturing machine for producing tobacco industry articles

A filter for a cigarette has an organic filtering portion defined by granules or fibres of active carbon and housed inside a cylindrical shell of plastic material; the shell is located between a portion of cellulose acetate, which is engaged orally by a user, and a cigarette portion, and has a bottom, contacting the portion of cellulose acetate and hermetically supporting a particulate trap for retaining fine particulate, and an end contacting the cigarette portion and closed by a plug of cellulose acetate.
