Abstract
A device and a method for folding a print substrate web is disclosed. The device has devices for quarter folding and for cross-cutting the print substrate web for severing individual products as well as devices for cross folding. As viewed in the transport direction of the products, an arrangement for dividing the product stream is provided after a second quarter folding device, the arrangement conveying the successive products to a first and a second conveyor belt in an alternating manner.
Claims9
A device for printing and folding a print substrate web, comprising:
- a web-fed rotary printing press having double circumference plate cylinders, wherein the print substrate web is printable by the web-fed rotary printing press;
- a first quarter fold device;
- a cross cutting device, wherein the cross cutting device is disposed downstream in a transport direction from the first quarter fold device;
- a cross fold device, wherein the cross fold device is disposed downstream in the transport direction from the cross cutting device;
- only one second quarter fold device, wherein the only one second quarter fold device is disposed downstream in the transport direction from the cross fold device;
- a splitter, wherein the splitter is disposed downstream in the transport direction from the only one second quarter fold device;
- and
- a first conveyor and a second conveyor;
- wherein successive printed products severed from the print substrate web by the cross cutting device are conveyable by the splitter to the first conveyor and the second conveyor in an alternating manner;
- wherein the first conveyor and the second conveyor convey respective printed products to a first fan wheel and a second fan wheel, respectively;
- wherein a common drive drives the splitter and the first fan wheel and the second fan wheel and wherein the common drive does not drive other devices.
A method for printing and folding a print substrate web, comprising the steps of:
- printing the print substrate web by a web-fed rotary printing press having double circumference plate cylinders;
- folding the print substrate web with a first quarter fold parallel to a transport direction of the print substrate web by a first quarter fold device;
- severing the print substrate web to form individual print products by cross-cutting the print substrate web;
- cross folding the individual print products;
- folding the individual print products with a second quarter fold by only one second quarter fold device;
- and
- conveying successive individual print products to a first conveyor and a second conveyor in an alternating manner by a splitter following the step of folding the individual print products with the second quarter fold;
- wherein the first conveyor and the second conveyor convey the respective successive individual print products to a first fan wheel and a second fan wheel, respectively;
- wherein a common drive drives the splitter and the first fan wheel and the second fan wheel and wherein the common drive does not drive other devices.
