Printing press including a mechanism for exchanging cylinders

Abstract

A printing press consists of several printing units arranged in a row, each having one inking unit, and cylinders exchangeable for diverse print runs, the bearings of the exchangeable cylinder being arranged on a carriage displaceable in the printing press frame. An impression cylinder is mounted in the printing press frame. The printing press includes means for lifting out and removing the exchangeable cylinders. The conveyance means has a trolley displaceable on a rail. To allow the cylinders to be easily and rapidly exchanged the carriages are displaceable on at least one horizontal guide means of each printing press frame. Lifting jacks are assigned to the shaft journals projecting outwardly from the bearings. The trolley is displaceable on a rail approximately parallel to the carriages of all the printing units, extends over the length of all the printing units, and has assigned to each printing unit pairs of freely projecting arms which are substantially parallel to the carriage guide means, with receiving means for the shaft journals of the exchangeable cylinders. The lifting jacks can be lifted above the arms.
