Abstract

995,891. Printing apparatus. DRUCKMASCHINENWERK PLANETA VEB. Aug. 31, 1962, No. 33508/62. Heading B6C. In the offset cylinder 2, Fig. 1, of an offset rotary printing machine that edge, 12A, Fig. 2, which first comes into contact with the impression cylinder 1 at the commencement of a printing operation is set back from the periphery of the cylinder towards its axis by an amount S equal to the distance which the cylinders move apart during the printing operation due to the play in the bearings 15, 16, 17, 18, of the offset and impression cylinders. The surface area of the offset cylinder from said leading edge 12A to a cylindrical generatrix 13A of the cylinder where the cylinders no longer move apart, is formed as a curved run-on surface which merges into the outer periphery 10 of the offset cylinder. The run-on surface, which may be parabolic, is so curved that the pressure between the cylinders is the same at any position when the curve is in contact with the impression cylinder as it is at any other time during the printing operation.
