Abstract

See full text

A printing press with crop mark setting device and process is provided. A printing couple for printing on a web is used with a lengthwise cutting device for cutting the printed web lengthwise into a first web strand and at least one second web strand. A convergence device converges the web strands or for converging the web strands with at least one other web strand each to provide one or more converged web strands, the convergence device including a turning bar device. A cross-cutting device cross-cuts the converged web strands. A crop mark sets a crop mark of the web strands that is related to the cross cutting. The crop mark setting device has a first deflecting device for deflecting the first web strand around a first deflection axis and a second deflecting device for deflecting the second web strand around a second deflection axis. The second deflecting device is mounted movably in relation to the first deflecting device in a frame such that a length of a path of the second web strand in relation to the length of the path of the first web strand can be changed by a movement of the second deflecting device in relation to the first deflecting device. The crop mark setting device is arranged in front of the turning bar device with respect to a direction of delivery of the web.
