ABSTRACT:
An apparatus for cleaning cylinders of a rotating drum printing machine has a cleaning cloth, which can be unwound, and a contacting body. The cleaning, which otherwise is carried in fixed time regions, for which precisely dimensioned cloth sections can be made available, is changed to a measure, which is carried out with an alternating contacting pressure of the contacting body and a quasi continuous advance of the cloth. In the contacting zone, the cloth is taken hold of directly and pulled. An oscillating mechanism, which is preferably realized pneumatically, is provided for the alternating contacting pressure.
