Abstract
A printing press provides a pair of cylinders mounted for rotation about parallel axes. At least one of the cylinders carries a member wrapped thereon having circumferentially spaced edges defining a gutter. When the cylinders are rotated, an impact is generated when the gutter juxtaposes the adjacent cylinder thereby generating oscillatory movement in at least one of the cylinders. An impact damper mechanism is provided for minimizing the amplitude of all oscillations occurring after the gutter moves out of the nip and for rapidly degrading the following oscillations.
