US 2011/0209638 A1 · SUPERSTRUCTURE OF A PRINTING PRESS, AND METHODS FOR USING A PRINTING PRESS

Abstract

A superstructure of a printing press includes a turning tower with at least one turner bar that is usable to deflect a web section from a transport direction by 90°. A second turner bar, that is shorter than the first turner bar, is also used to deflect a web section from the transport direction by 90° in the same direction as the first web section. These first and second turner bars are offset vertically in relation to one another in the same turning tower. The first turner bar is supported at both ends on at least one first lateral support and at least one second lateral support. The second turner bar is supported only on one end on the lateral support in a floating manner. The second support side of the second turner bar is provided with access from that support side into the interior of the turning tower.

A superstructure of a printing press comprising a turning tower (07) with at least one first turning bar (17). which can be used to deflect a web ribbon 90° in its direction of transport, and with at least one second turning bar (16), which is shorter than the first turning bar (17), and which can be used to deflect a web ribbon 90° in its direction of transport, to the same direction as the first web ribbon, characterized in that the first and second turning bars (17;

16) are arranged in the same turning tower (07) offset vertically, in that the first turning bar (17) is at least supported at both ends on a first and a second side frame (12;
14) and the second turning bar (16) is mounted at only one end, cantilevered, on the first of the side frames (12), and in that the second frame side (14) is embodied with access (13) in this frame side (14) into the interior of the turning tower (07).

A printing press comprising at least one first printing unit (01) and one turning tower (07) disposed in the same machine alignment (F), through which a web (02;

02′), or a partial web (02,x:
02′,y) cut from said web, guided through the printing unit (01), can be deflected 90° out of the machine alignment (F) to a former structure (08;
08′), which is aligned with the turning tower and which is aligned, in terms of its direction of web travel of the entering web (02 02′) or partial web (02,x;
02′,y), rotated 90° from the machine alignment (F). and which has at least one former plane with at least two fold formers (09.1;
09.2) arranged side by side, characterized in that the usable widths of the two fold formers (09.1;
09.2) are different from one another, and in that at least one of the two fold formers (09.1;
09.2) is embodied as movable transversely to the direction of web travel,
