The filter tipping machine 10 is represented in section, wherein for reasons of clarity of the drawing, further unit(s) or respectively devices, are omitted. The backside of the filter tipping machine 10 can be seen in FIG. 1. Further, the filter tipping machine 10 has a (not visible) machine frame in which conveyor drums and further devices necessary for the operation are arranged.

(8) The laser supply unit 20, established separately here, is arranged behind the backside of the filter tipping machine 10 and has its own supply frame (not represented here). The laser supply unit 20 is designed having a closed housing.

(9) A laser device 30 is arranged on the top side of the filter tipping machine 10 using an adapter unit (not shown in detail), so that the laser device 30, for example a CO.sub.2 laser, can be releasably arranged for generating laser beams on the machine so that with use of the laser beams perforations are created in the filter cigarettes or the components thereof produced with the filter tipping machine 10. The laser device 30 is arranged above the machine frame of the filter tipping machine 10 and connected thereto with the interposition of the adapter device.

(10) For operating the laser device 30, the externally, or respectively separately, arranged laser supply unit 20 is connected via a connection channel 25 to the laser device 30 in order to appropriately control and operate the laser, or respectively the laser device 30. The supply units or supply modules necessary for the operation of the laser device 30 are arranged, or respectively housed, here in the laser supply unit 20.

(11) FIG. 2 shows a perspective view in section of a further example embodiment of an arrangement of a filter tipping machine 10 and a separately arranged laser supply unit 20. The laser supply unit 20 is arranged here behind the backside of the filter tipping machine 10, wherein a laser device 30 is arranged in the laser supply unit 20. The laser device is not visible due to the protection, or respectively the closed housing of the laser supply unit 20.

(12) A compact design is attained due to the arrangement of the operating devices for the laser device and the arrangement of the laser device in the laser supply unit 20. For connecting and for guiding the laser beams generated in the laser supply unit 20 via the laser device 30, a beam guidance device 27 is provided in the form of a duct or the like, in order to guide the laser beams from the laser supply unit 20 to the processing sites on the filter tipping machine 10 for processing, or respectively for perforating, rod-like articles and/or the components there of (not shown here).
