Abstract: An arrangement and method for conveying rod-shaped articles of the tobacco-processing industry. The arrangement conveys article segments of first and second rows disposed side by side in pairs in a transverse axial direction. In a conveying inspection section, at least one conveying member conveys a first row of article segments disposed transversely axially behind each other and conveys a second row of article segments disposed transversely axially behind each other. Moreover, one or two head end inspection devices, preferably optical, are provided for inspecting one or both head ends of the first row of article segments along a conveyor path for the first row of article segments of the first row, and one or two head end inspection device, preferably optical, are provided for inspecting one or both head ends of the second row of article segments along a conveyor path for the second row of article segments.

Abstract: A roller for a device for processing a filter material ribbon in the tobacco-processing industry. The roller comprises a roller core and a covering for the roller core. The roller has at least one wear indicator operatively arranged for indicating wear of the covering.

Abstract: Conveyor drum, machine, and process of the tobacco-processing industry. The conveyor drum includes seats structured and arranged for rod-shaped articles of the tobacco-processing industry, displacement devices, composed of mechanically operable and moveable pushers, structured and arranged for longitudinal axial displacement of the rod-shaped articles in the seats, and a region structured and arranged to receive a cutting device. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.

Abstract: Staggering drum for conveying rod-shaped articles of the tobacco processing industry arranged in at least two rows next to one another. The staggering drum includes at least one conveyor disk with seats for a row of articles, and at least one of the seats includes at least two suction bores structured and arranged to be coupled to a vacuum. At least one of the at least two suction bores being not disconnectable from the vacuum in a transport area of the articles. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.

Abstract: Rod-shaped articles of the tobacco processing industry are advanced lengthwise in a conduit by a first air flow. Blasts of compressed air are admitted into the conduit behind successive articles to promote their advancement in a larger-diameter arcuate section of the conduit, particularly from a lower level to a higher level. The admission of successive blasts of compressed air is carried out by an open-and-shut valve which receives signals from an article detector located downstream of the valve.
