It is now a decade since Wetzlardruck started to use a Muller Martini NewsLiner to include inserts in the daily newspaper “Wetzlarer Neue Zeitung” (four issues/total circulation of 76,000 copies) and the Sunday newspaper “Guter Sonntag” (three issues/total circulation of 160,000 copies). The newspaper manufacturer in Hesse is so pleased with this machine that when investing in a second, older inserting line from a different manufacturer, it - together with its consultant Reinhard Krick from the engineering firm Ingenieurbüro Krick - again opted in favor of a solution from Muller Martini.

The new inserting system, to be commissioned this coming May, was pushed for not least because both papers are including increasing numbers of inserts and featuring pre-printed sections to a greater extent. The number of inserts in a single issue can be as high as 20.

Buffering, Inserting, Film Wrapping, Strapping
Using a folder delivery on the printing press, products are automatically led to the new FlexiRoll buffer on a NewsGrip A newspaper conveyor. The main product and any pre-printed sections are then fed via rollers into the nine stations on the extensive ProLiner, where up to eight inserts can be added using four long and short stream feeders. This provides Wetzlardruck with the ideal way of separating print press and mailroom operations.

Following this, products are transported on a gripper conveyor from the ProLiner into two NewsStack stackers. The finished standard and key bundles are then labeled, film wrapped and strapped using two TABA F (thermal print) top sheet applicators. To accommodate particularly high production volumes, one of three CN80 systems belonging to the NewsLiner line can also be deployed. This stacker is installed in such a way that it can be used flexibly, either with the NewLiner or the ProLiner.
