About Us

Masterwork Machinery GmbH in Neuss near Düsseldorf is a 100% subsidiary of Masterwork Group Co., Ltd. in Tianjin, China. We are a successor company of Jagenberg Diana GmbH and of the folding carton gluing division of Heidelberger Druckmaschinen AG.

Within the Masterwork Group, we are responsible for research and development of folder gluers and peripherals as well as handling robots. Nearly all of our employees have a technical qualification in the field of mechanical or electrical engineering. As a research and development site, we also have a large test facility with its own folder gluers and robots.

Our Diana folder gluers and robot grippers are produced in our factory in Nové Mesto nad Váhom in Slovakia.

Our Diana folder gluers are sold through the sales and service network of Heidelberger Druckmaschinen AG, except in China, where we operate our own sales and service companies. The handling robots are sold directly by us. 

A brief history recap!

A century of experience has been incorporated into our folder gluers, which have been sold under the Diana brand for more than 60 years.

The story of our folder gluers began at Jagenberg in Düsseldorf. More than 60 years ago, the Diana brand was introduced. Known throughout the world, this name stands for folder gluers of superior quality.

In 2003, Heidelberger Druckmaschinen AG took over the folder gluer division of Jagenberg and further developed the Diana folder gluers until 2015. 

At the end of 2015, the division was taken over by the Masterwork Group, China’s market leader for post-press machines. Over the years, the quality of the Diana folder gluers was consistently raised by these three leading engineering companies.
