Abstract: A method for applying adhesive on a wrapping band of a smoking article includes moving the band along a feed direction, the band has a longitudinal direction of extension, opposing first and second surfaces, a first plurality of portions having a first thickness and a second plurality of portions having a second thickness greater than the first thickness, the portions of the first and second pluralities being disposed alternately along the direction of extension. A nozzle having a delivery end, and the band are moved towards/away from each other between a first position, where the delivery end and the second surface are at a first distance which is less than or equal to the second thickness, and a second position, where the delivery end and the second surface are at a second distance greater than the second thickness. An adhesive is delivered on the first surface through the nozzle.

Abstract: A wrapping device 1 for wrapping a sheet 3 around a group 5 of segments comprises a wrapping conveyor 7 and a contact element 25. The wrapping conveyor 7 comprises a conveyor surface 9 for receiving the group 5 of segments. The contact element 25 provides a counter surface 31. The counter surface 31 is arranged at a distance to the conveyor surface 9 of the wrapping conveyor 7. The counter surface 31 faces the conveyor surface 9 of the wrapping conveyor 7. The counter surface 31 is configured to engage the group 5 of segments and the sheet 3 when the group 5 of segments is moved along the counter surface 31 by the wrapping conveyor 7 to cause rotation of the group 5 of segments to wrap the group 5 of segments with the sheet 3. At least a first portion 41 of the contact element 25 comprising at least a first part 35 of the counter surface 31 is formed by a first material being an elastic material having a shore hardness between 30 A and 70 A.

Abstract: The invention relates to a conveying system comprising a conveyor rail configured for conveying heat sources for aerosol-generating articles. The system further comprises a heat source detector configured to detect heat sources conveyed by the conveyor rail. The system further comprises a moving actuator. The moving actuator is configured to move the conveyor rail in a direction perpendicular to the conveying direction. The moving actuator is configured to move the conveyor rail if the heat source detector detects absence of heat sources for a predetermined time.

Abstract: A device for combining filter segments with cigarette rod segments includes a first feed device for feeding a succession of gummed connecting strips and a second feed device for feeding a succession of groups, each including at least one cigarette rod segment and one filter segment, abutted end to end. A combining conveyor receives the groups in a first receiving station and the succession of strips in a second receiving station downstream of the first receiving station so that each gummed connecting strip is applied in flag-like manner on a respective group to connect the cigarette rod segment to the filter segment. A rolling drum receives the group with strip and rolls the strip round the group. A compression device downstream of the second receiving station and upstream of the release station produces compression between each group and the respective strip.

An adhesive is delivered on the first surface through the nozzle.

Abstract: A transfer or feed drum for filter or cigarette portions, the drum having: a central body mounted to rotate about a first axis of rotation; a number of movable assemblies, each of which is fitted to the central body to rotate, with respect to the central body, about a respective second axis of rotation parallel to the first axis of rotation, and supports a pickup or feed head having at least one seat with a U-shaped cross section and for engaging at least one filter or cigarette portion; and an actuating system, which controls the angular position of each movable assembly about the respective second axis of rotation as a function of the angular position of the central body about the first axis of rotation.
