  • the cleaning roller 46' is basically of the same design as the cleaning roller 46. It also includes a pin 122 on a side facing away from the counter-element 60.
  • a slide 124 is arranged on the cover 120, which together with the pin 122 forms a locking device 126 for the axial locking of the cover 120 with the cleaning roller 46'.
  • the slider 124 has a recess 128 into which the pin 122 is immersed. In a locking position (cf figure 16 ) the pin 122 is immersed in the recess 128. The slider 124 is in such a displacement position that it is blocked for the pin 122 to emerge from the recess 128 . As a result, the cleaning roller 46' is axially fixed (in a direction parallel to the axis of rotation 50) to the cover 120.
  • This locked position can be released by moving the slide 124 .
  • the lock is then released and the pin 122 can emerge from the recess 128 on the cover 120 . This allows the cleaning roller 46' to be detached from the cover 120.
  • this embodiment functions in the same way as described above.
  • the cleaning roller 46' is not mounted loosely on the cover 120, but an axial locking is possible.
  • the cleaning roller 46' In order to insert the cleaning roller 46' into the corresponding roller receptacle 42, the cleaning roller 46' is first locked to the cover 120 by the pin 122 is brought into the recess 128 and the slide 124 is then brought into its locking position.
  • This axial connection is such that the cleaning roller 46 ′ can be rotated relative to the cover 120 .
  • a corresponding rotary bearing 130 is arranged on the cover 120 for this purpose.
  • the cleaning roller 46' can then be pushed into the roller receptacle 42 in this combination.
  • the corresponding bracket 69 on the cover 120 is in its release position 118 and the holding bodies 86, 90 can then be immersed in their respective receiving spaces 102. Locking is achieved by pivoting the bracket 69 into its locking position 114 .
  • cover 120 and cleaning roller 46' which are axially connected to one another, is removed from the roller housing 14 (cf figure 14 ). After the cover 120 has been removed from the cleaning roller 46', it is then released by corresponding displacement of the slide 124 from its locking position.
