Abstract
To distribute loading, and reduce wear, on filler inserts upon roll-off of printing machine cylinders formed with axial grooves, such as rubber blanket cylinders in offset printing machines, the filler insert is formed with an axially curved edge or surface (9, 10; 16, 18) which, either, is provided at the engagement surface of the respective filler insert element with the bottom wall (23, 24) of the groove (3, 4) or, alternatively, at the outer or top surface. The degree of curvature is such that, with respect to a flat surface tangent to the curved surface, a spacing or gap of, at the most, 0.2 mm, and preferably only about 0.1 mm, will result.
