A roller drum (23) for finishing filter-tipped cigarettes by over-wrapping and connecting cigarettes and filter sections (42) by means of a connecting sheet (43) is, for the purposes of cleaning the corresponding roller surfaces (26), assigned a roller block (46) with a relatively short roller surface (47) which, during the operation of cleaning rolls the abovementioned components between two retaining troughs (53) receiving the components, or partially connects them to each other, and releases the abovementioned components or removes them from the roller drum before the subsequent retaining trough is reached, so that the cleaning operation can be undertaken without interruption. <IMAGE>
