SUCCESS STORIES - Liebensteiner Kartonagenwerk
Precisely on edge at high speed
The areas of application for protective and outer packaging made of corrugated cardboard are almost unlimited. The customer list of Liebensteiner Kartonagenwerk GmbH in Plößberg in the Upper Palatinate is correspondingly long. The company relies on strapping machines from Mosca GmbH to secure its own products for transportation. The latest addition to the production hall is the brand new UATRI-2 high-performance machine.
"The strapping machines meet a wide range of requirements in terms of production speed and transport bundling."
Liebensteiner produces and supplies everything from the smallest boxes to large protective cardboard boxes for furniture. What began in 1968 as a two-man operation with very small quantities of ten to 20 boxes is now a large corrugated cardboard processing company that covers all the steps involved in the production of cardboard boxes.
The company's customers in Germany and beyond primarily include the automotive and supplier industry, personal care products production and mechanical and plant engineering. Bernhard Schön, the son of the company founder, has been running the family business for over 30 years. Today, 230 employees process around 60 million square meters of corrugated cardboard per year for around 1,200 customers, individually cut and printed in four colors as required, in batch sizes of up to 100,000. Ten cardboard production lines are now in daily operation.
Precise and clean strapping
From simple RO-MP plastic strapping machines, which are used for small orders and operated manually, to fully automatic UATRI inline machines and pallet packing presses, the entire Mosca range is in use at Liebensteiner.
The fully automatic UATRI-2 strapping machine was specially designed for automated lines with high production speeds. Liebensteiner acquired one of the first models as part of a major investment in 2009, which has now been in Plößberg since February 2010. This high-performance machine is characterized by increased productivity, simple operation and exceptional reliability.
The UATRI-2 straps up to 30 parcels per minute in single or double stacks that are precisely aligned. Compared to the predecessor model, the pneumatic drives have been replaced by more cost-effective electric motors, which not only work more accurately but also more quietly. The integrated alignment station ensures that incoming stacks are straightened and held in place from all sides with alignment plates from a press. The stacks therefore leave the machine with precise edges and neatly strapped, even at the highest production speeds.

Increased productivity
Thanks to the fully automatic process connection, set-up and downtimes are reduced to a minimum. With the help of an online data transfer from the upstream inline machine, the UATRI-2 adjusts to the dimensions of the packages of a new size during set-up. Two reel holders also eliminate the need to interrupt production to change reels manually. If one strap reel has run out, a new Strap is automatically welded on without interrupting the production process.
Company boss Schön is impressed by this user-friendliness: "In the past, you had to enter the exact dimensions of the package to be strapped into the computer for each new batch so that the machine could adjust to them. This is no longer necessary with the UATRI-2: as soon as the first package arrives, the machine automatically adjusts to the new dimensions."
Satisfied customer
Cooperation with perspective
Over the years, Liebensteiner and Mosca have developed a close working relationship. Konrad Haner, Head of Technology at Liebensteiner, particularly praises the reliability of Mosca GmbH, which also takes care of occasional problems. And to ensure that the machines run as smoothly as possible, the cardboard packaging plant and Mosca work together in a spirit of trust: Haner passes on its experience with new equipment and suggestions for improvement to Mosca and Mosca returns the favor with appropriate adaptations, which often go into series production. Haner and Mosca's engineers are also working together on the UATRI-2 to make the highly developed machine even better in the future through the finest adaptations.
"Set-up times for the machine can almost be ignored in the calculation"
