A cleaner drive assembly used for driving a belt cleaning device such as a shower pipe unit provided in a papermaking apparatus having a sheet forming station including an endless belt to forwardly carry a wet web of paper thereon, the belt cleaning device being used to clean the endless belt by applying streams of liquid to the belt and being movable in opposite directions substantially parallel with the direction of width of the belt. The cleaner drive assembly is adapted to drive the belt cleaning device alternately in the aforesaid opposite directions and comprises a drive unit to produce rotary motions in alternately opposite directions, a rotary-to-axial motion converting unit to convert the rotary motions into reciprocating axial motions, the directions of the reciprocating axial motions being aligned with the opposite directions in which the belt cleaning device is movable. The rotary-to-axial motion converting unit is in driving engagement with the belt cleaning device for transmitting the reciprocating axial motions to the belt cleaning device.
