Abstract
A product section is produced in a printing machine that has at least one former. A web or a partial web of material is guided over the former. At least one web or one partial web is initially guided over a plow fold device and then over one, or another odd number of turning bars. This at least one web or partial web is then united, without passing through the former, and on a side that has been folded in by the plow fold device, over at least one guide roller as a partial strand with a partial strand that was guided over the former as a strand bundle before this partial strand is cut transversely in a transverse cutting direction into product sections.
Claims24
A method for producing a product section in a printing press including:
- providing one of a first web and a first partial web;
- providing at least one fold former in said printing press;
- guiding said first one of said first web and said first partial web over said at least one fold former and forming a first partial ribbon;
- providing one of a second web and a second partial web;
- providing a plough folding apparatus in said printing press;
- guiding said one of said second web and said second partial web over said plough folding apparatus;
- using said plough folding apparatus and folding at least one side of said one of said second web and said second partial web in, and forming a second partial ribbon;
- providing an uneven number of turning bars and directing said second partial ribbon over said turning bars;
- providing at least one guide roller in said printing press;
- combining said first partial ribbon, after being guided over said at least one fold former, with said second partial ribbon guided by said guide roller, and without being guided by said at least one fold former, and forming a ribbon bundle;
- providing a cross-cutting device;
- and
- using said cross-cutting device and cross-cutting said ribbon bundle into said product sections.
A method for producing a product section in a printing press including:
- providing a first partial web printed with printed pages having a width of a first format;
- providing at least one fold former;
- guiding said first printed web over said at least one fold former;
- providing a second partial web printed in tabloid configuration and having one of a one and two part printed page in a second format, said second format being larger, by a projection, than said first format;
- providing an uneven number of turning bars;
- guiding said second partial web, printed in said second, larger format, over said uneven number of turning bars and without passing through said fold former;
- providing at least one guide roller;
- locating said at least one guide roller downstream, in a direction of web travel, of said uneven number of turning bars;
- directing said second partial web over said at least one guide roller and combining said second partial web with said first partial web which has been guided over said at least one fold former and which contains said printed pages in said first format, smaller than said second format, and forming a ribbon bundle;
- providing a cross-cutting device;
- and
- cross-cutting said ribbon bundle using said cross-cutting device after combining said first partial web and said second partial web and forming said product sections.
A device for producing a product section in a printing press comprising:
- at least one printing unit;
- at least one former assembly including at least one fold former, said at least one former assembly forming at least one first partial ribbon having one of a first web and a first partial web, said at least one first partial ribbon being guided over said fold former;
- at least one plough folding apparatus and at least one turning bar located in a web path of travel of a second partial ribbon including one of a second web and a second partial web which passes through said plough folding apparatus;
- and
- an output of said former assembly, said first partial ribbon, which is guiding over said fold former, and said second partial ribbon, which passes through said plough folding apparatus without passing through a fold former, being combined at said outlet of said former assembly to form a ribbon bundle.
