Method and device for compensating vibrations of side frames in printing units of rotary presses

摘要

A method for damping lateral vibrations in a printing press, e.g. a newspaper press line, has a damping mass (3) sliding on a bar (4) linking the two side frames (1) of the press. The bar is braced between two springs (5) with similar spring characteristics. The spring tension is adjustable via thrust plates on a screw mounting on the support bar. The whole damping system is encased in a cylindrical shell (2) between the press frames.
