[0073] Figure 1 shows a prior art rotary printing machine 1, in particular a newspaper printing machine, with a folding unit 2 consisting of a newspaper folding unit 3 and a press for newspapers and selected commercial products. It is composed of 4 fixed and immovable folding triangles. The rotary printing press 1 consists of printing units 5-7, of which the printing unit 5 is used for printing selected commercial products and the printing units 6, 7 are used for printing newspaper products. All printing units 5 to 7 are newspaper printing units. The selected commercial product, ie the web printed in the selected commercial product quality, is conveyed to the folding unit 2 by means of a drying device 9 along the web path 8 (thermosetting-web path). The newspaper product, ie the web printed in newspaper quality, is conveyed along the web path 10 (coldset-web path) to the folding unit 2 . Both newspaper products and select commercial products pass through the same folding for...

Description

technical field [0001] The invention relates to a folding unit of a web offset press for combined newspaper and selected commercial product production as defined in claim 1 . Background technique [0002] Web offset printing is mainly divided into the following categories: web offset printing for newspaper printing (cold set), web offset printing for illustration printing (heat set) and web offset printing for semi-commercial product production. [0003] Semi-commercial products are also known as select commercial products. Only the concept of selecting commercial products is used below. Newspaper printing is characterized by printing with cold-set inks, while illustration printing is characterized by printing with heat-set inks. [0004] Semi-commercial products or select commercial products are included in the product area between newspaper printing and illustration printing. This relatively new concept is a new product among the printing products with continuously enri...
