Abstract (en)

[origin: EP0790125A1] The cleaning device cleans the surfaces of cylinders (1). A cleaning cloth (4) extends over the length of the cylinder. A pressing element acts on the cloth to press it to the cylinder. The pressing element consists of an elastically deformable hollow body (5). When internal pressure is applied to the hollow body, it expands elastically, increasing the spacing towards the cylinder surface. Air is supplied to the hollow body via a two-way valve (8). The two-way valve can be switched from excess pressure to negative pressure, so that the hollow body can pass from an outward position via a neutral rest position to a position stretched inwards.
