  • the bracket 69 is pivoted into its locking position 114.
  • the first receptacle 84 and the second receptacle 88 are rotated and the second opening 110 is pivoted such that the corresponding first neck 98 and second neck 100 are positioned on it.
  • the wall 112 then acts as a blocking element.
  • the locking position 114 it is fundamentally possible for the locking position 114 to be additionally secured.
  • spring loading of the bracket 69 can be provided and a spring force must be overcome in order to bring the bracket 69 from the locking position 114 into the release position 118.
  • pivot bearing 92 it is also possible for the pivot bearing 92 to be “difficult to move” in such a way that an increased expenditure of force is necessary in order to reach the release position 118 from the locking position 114.
  • the cleaning roller 46 ' can be axially locked with a cover 120.
  • the cleaning machine is of the same design as the cleaning machine 10 and the same reference numerals are used for the same elements.
  • the cleaning roller 46 is basically of the same design as the cleaning roller 46. It additionally comprises a pin 122 on a side facing away from the counter element 60.
  • a slide 124 is arranged on the cover 120 and, together with the pin 122, forms a locking device 126 for axially locking the cover 120 with the cleaning roller 46 '.
  • the slide 124 has a recess 128 in which the pin 122 is immersed. In a locking position (see FIG. 16), the pin 122 is immersed in the recess 128. The slide 124 is in such a displacement position that the pin 122 is prevented from emerging 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 locking position can be released by moving the slide 124.
  • the lock is released and the pin 122 can emerge from the recess 128 on the cover 120.
  • the cleaning roller 46 ′ can be detached from the cover 120.
  • the cleaning roller 46 ' is not loosely mounted on the cover 120, but an axial locking is possible.
  • the cleaning roller 46' is first locked with the cover 120, in which 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 pivot bearing 130 is arranged on the cover 120.
  • 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 roller housing 14 (compare FIG. 14). After the cover 120 has been removed from the cleaning roller 46 ', it is then released from its locking position by a corresponding displacement of the slide 124. LIST OF REFERENCE NUMBERS
