Patented in the German Empire on December 22, 1911.

It has already been proposed to set up printing presses in such a way that they combine the properties of rotary machines and high-speed presses. Further it has been suggested that some of these presses should print both forms on the same side of the sheet and on other presses the imprint of each shape one per. Side of the bow to be made,

ίο so in the first case one-sided two-color printing, in the latter case to produce the so-called single-color front and back printing.

The former type of press enables one to produce rotary printing. place, i.e. to print on one side without the involvement of the flat shape. None of these Presses, however, it is possible to use the same press either as a combined rotary and high-speed press or alternately as a rotary press or only as a high-speed press to be able to.

The purpose of the present invention is now essentially to provide a press to create, in which both the above named printing work as well as various other working methods are to be carried out. In addition, one should be at the same be able to be reprinted from a typographical or lithographic flat shape as well as typographic or lithographic to be able to produce cylindrical shape.

In particular, the invention relates to a two-turn machine that either can only be used as a high-speed press or a rotary press or as a high-speed press and a rotary press at the same time. So she can z. B. as a high-speed press for the production of single-color printing, as a direct printing lithographic Press for single-color printing, 'as a direct printing press for single-color printing, as a lithographic or typographic original printing press for the production of monochrome printing, as lithographic or typographic or combined lithographic and typographic Press for two-color printing, as a press for printing with two colors, of one of which is used for direct printing and the other for transfer printing, or as lithographic or typographical or as lithographical and typographical straight and reverse or transfer printing in use be taken. The invention is described below with reference to the drawings illustrated schematic view will be described, which an embodiment of the new press with the in application different organs to be brought in illustrated.

The main parts of the press are as follows:

A flat shape for letterpress or lithographic printing i.

A cylinder 2, which can act as a printing cylinder and as an OR as a transfer or transfer cylinder. This cylinder (hereinafter referred to as the pressure cylinder) is equipped with two different pressure surfaces 3, 4. Each of these surfaces has its own gripper set "3" or "4" as well as a clamping device 5 for a printing or transfer blanket . Can be placed out of print position with relation to the printing cylinder 2. A transfer or transfer printing cylinder 8, which is arranged above the printing cylinder 2 and is equipped with a device in order to be able to be brought into or out of printing division with relation to the printing cylinder 2. Moistening devices i ^a , 2 ^a and inking devices ι ⁶ , 2 ^δ for the flat printing forme 1 and the forme cylinder 6. The usual device by which the printing cylinder 2 can be set in and out of the printing position with relation to the flat printing forme 1 and the device through which the drive device the flat shape can be placed.
