A printing machine for printing on a printing substrate web includes a plurality of inline flexographic printing units which are disposed in a plane accessible to an operator of the machine. Each one of the two flexographic printing units of a respective duplex printing station includes a respective impression cylinder and a dryer disposed between the two impression cylinders along a path of web travel of the web of printing substrate. A method of operating the printing machine is also provided.

Printing machine with a twin printing unit and method of operating such a printing machine

In a method for operating a rotary printing press, preferably a flexographic printing press that processes webs, disturbances of a rotating printing cylinder are detected and reduced by changing the printing speed. Here, the disturbances are detected at an actuating drive of the printing cylinder. This leads to a cost-efficient way of printing without disturbances.

A method for feeding a web of printing material in a manufacturing system for producing packages, includes feeding the web from a web-fed printing press to a flat-bed machine for die-cutting or embossing while the printing press is in operation. An inserting device is used for winding the web onto an auxiliary wind-up device, moving a web-guiding element having a roller in a compensatory manner to achieve a temporary standstill of the web by converting a continuous movement of the web into an iterative movement by changing a speed of the web through changes of position of the roller, clamping the web while being cut by using a clamping unit, cross-cutting the web creating a cross cut edge by using a cutting unit adjacent the clamping unit, and inserting the web, cross cut edge first, into the flat-bed machine for at least one of die-cutting or embossing.

A device for inserting a web of printing material into a flat-bed die-cutting and/or embossing machine includes a compensator for converting a continuous movement of the web of printing material into an iterative movement of the web of printing material. A clamping unit clamps the web of printing material, a cutting unit carries out a cross cut through the web of printing material, and an inserting unit transports the web of printing material into the flat-bed die-cutting and/or embossing machine. The device advantageously allows the web of printing material to be automatically clamped, cut and fed to the flat-bed die-cutting and/or embossing machine. As a result, no further stopping of an upstream printing press is required and the amount of waste is reduced. A manufacturing system for producing packages and a method for feeding a web of printing material are also provided.

A flatbed punching module for punching a printing material includes an upper platen and a lower platen which can be moved by a drive relative to the upper platen that is fixed to a frame, in order to perform a punching stroke for punching the printing material passing between the upper platen and the lower platen, resulting in the lower platen engaging with or being thrown onto the upper platen. As a result, the printing material can be processed through the use of at least one punching die. At least one printing material transport device for guiding the printing material, is held fixedly on the movable lower platen. The flatbed punching module can advantageously be used in a flatbed punch for processing a printing material web.
