ABSTRACT:
The vertical cylinder screen in a cleaning machine is adapted to be given a rotary motion at oscillating angular velocity. This is obtained with this invention in that the cylinder screen is adapted to be given an oscillatory motion by means of a driven eccentric unit coupled to it and a rotary motion in that the eccentric unit is mounted on a carrier therefor which is adapted to rotate about the center shaft of the cylinder screen.
