Description

The The invention relates to a folding unit for web-fed rotary printing machines with combined newspaper and selected commercial production according to the generic term of claim 1.

• – Rollenoffsetdruck für den Zeitungsdruck (Coldset)
• – Rollenoffsetdruck für den Illustrationsdruck (Heatset)
• – Rollenoffsetdruck für die Semicommercial-Produktion

Web offset printing can be subdivided into the following main groups:

• - web offset printing for newspaper printing (coldset)
• - web offset printing for commercial printing (heatset)
• - web offset printing for the semicommercial production

Of the Term "Selected Commercial "or" Semicommercial "means in the Printing Technology: Production area of web offset printing, the quality between newspaper printing and commercial printing. For this Task area are the newspaper roll offset printing machines with additional Equipment and facilities equipped. "Selected Commercial" is thus a technical term the particular already in the textbooks

• 2. Helmut Teschner, "Offsetdrucktechnik", 10th edition 1997, Pages 10/68 to 10/71

precipitation has found.

Of the Term semicommercial production is also under the synonymous term Selected commercial production known. In the following will only the term used Selected Commercial.

During the Newspaper printing can be characterized by the printing of Coldset colors, the feature of illustration printing is the processing heatset colors.

The Semicommercial production or Selected Commercial production should the production area between newspaper and commercial printing shut down. The still relatively new term has emerged from the ever-expanding Range of printed products and their diverse quality requirements. It but there is also a connection between it constantly expanding range of both sides coated or pigmented Papers and the Selected Commercial production. In pure newspaper printing (Coldset) are absorbent, processed quickly wegschlagende natural papers, which the printing ink only physically let dry, no thermal drying support is needed.

As soon as but papers come for processing that have some streak, or papers that have been densified by calenderage is often already a thermal support the drying necessary to prevent greasing or depositing and the web at all to process in the folder. The Selected Commercial production is characterized above all through the processing of heatset colors and corresponding papers on the one hand, and on the other hand, a greater variety of possibilities for the production of various printed products as a result of possible Fold variants for processing heatset and / or coldset printed paper webs.

Selected Commercial production means but also a combination of coldset and heatset printing, where the possibility a merge the printed in coldset or heatset webs to a printed product exists, but only coldset - or Heatset productions can be planned.

At Newspaper printing machines with the possibility additionally for newspaper production (preferably in coldset), in other types of production Produce printed products, such as Selected Commercials (preferably in heatset, but also in coldset or in combined Coldset / heatset production) usually comes in for newspaper production typical folding unit for use.

The options for the production of folded products depend heavily on the execution of the folder used, d. H. that for typical newspaper folders the possibilities for production in different types of folds and fold variants due to the technical characteristics of a newspaper folder are limited.

To In the prior art, the above-mentioned newspaper folders are used Realization of both newspaper and selected commercial productions consuming provided with facilities, which in particular for the Selected Commercial productions Improvements in folding possibilities and the folding quality to reach. Disadvantage is that above facilities for Improvement of the folding quality at Selected Commercial production disadvantageous in pure newspaper productions impact and the conversion of the folding unit during production change difficult.

In a further embodiment according to the prior art, at least two newspaper presses with the possibility of producing selected commercials are used Folders are used with the goal to use one folding unit each for a corresponding production (one folder for heatset, another for coldset productions). Disadvantage is that in this case two folders are needed, one folder is used especially for newspaper production and the other only for Selected Commercial production. This requires a number of folders corresponding to the number of folders as well as higher costs for web guiding devices and, moreover, more installation space for the entire printing system.

Of the Invention is the object of the above-mentioned disadvantages eliminate and one for changing Productions easy to convert folding unit with little space creating by means of which newspaper and selected commercial products manufactured can be.
