Abstract

An apparatus for developing a cylindrical surface in a printing press that has a device for writing and/or imaging on a rotatable printing form cylinder, the cylinder having a silicon-containing operating surface, the apparatus comprising a rotatable cleaning roller, an elastic cover and a fabric blanket over the cleaning roller, the cleaning roller having an optionally wettable cleaning surface, means for rotating the cleaning roller synchronously with or in opposition to the rotation of the printing form cylinder, means for selectively establishing and breaking contact between the cleaning roller and the printing form cylinder, whereby silicon particles created on the operating surface during writing and/or imaging are removed by contact between the operating surface and the cleaning cylinder.
