Abstract

A method and apparatus for separating at least two bridges, especially gripper bars, of a segmented transport system for printing materials, e.g. sheets of paper in a printing press, include a transport system having a segmented electric linear drive with first and second primary parts constructed as segmented long-stator. The drive has a plurality of secondary parts constructed as carriages. Each secondary part assigned to the first primary part and each secondary part assigned to the second primary part are coupled by a crossmember to form a movable bridge. Two bridges in the same segment are moved jointly. A first bridge, reaching into a further segment due to jointly controlled movement, is moved individually under closed-loop control and separated from a second bridge, for locating the two bridges in different segments during further movement. Electrical and mechanical collisions of the bridges or of the carriages can therefore be eliminated.
