Apparatus for cleaning a curved surface by employing the cloth principle, the apparatus having a roll for unsoiled cloth with unused cleaning cloth thereon, a roll for soiled cloth for taking up used soiled cloth, a pressing element for pulling unsoiled cleaning cloth off the roll for unoiled cloth and to bring it in contact with a surface to be cleaned by a movement of the element toward the surface, and means for pulling cleaning cloth off the roll for unsoiled cloth and for rolling soiled cloth up on the roll for soiled cloth by rolling up a part of the cleaning cloth that is longer or equal to the part thereof that is removed by the pressing element from the roll for unsoiled cloth independently of the respective diameters of the rolls for soiled and unsoiled cloth.

Apparatus for cleaning of curved surfaces employing the cloth principle

A method for driving a printing press having, (i) an impression cylinder, (ii) at least one cylinder group having (a) a blanket cylinder, (b) a printing form cylinder, and (1) an imaging device, (2) an inking unit, and (3) an inherent drive system, all for said printing form cylinder, (iii) a sheet feeding device, (iv) a sheet delivering device, (v) a drive wheel train connecting the cylinders and the inking unit, and (vi) optionally a main motor drive, the method comprising detaching the printing form cylinder from the drive wheel train, driving the printing form cylinder by the inherent drive system at imaging speed during image formation, and re-attaching the printing form cylinder after image formation to the drive wheel train in an operating phase position.

Method and device for driving a printing press with an integrated imaging device

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.
