ACTION! The camera pans across a 1 m x 60 cm Lego landscape. The ‘furnace’, which in a real plant would be used to cure the filter paper, is made from yellow Lego bricks. Motor-driven tracks from a toy digger are used for the production line while green and yellow Lego men ‘operate’ the spin-on filter line. Filter housings are pressed in the miniature transfer press ‘Corina’.

Some years ago, my sons Vitus and Johannes built their own Lego versions of some of the production facilities at the Marklkofen filter plant, and they did such a great job that we decided to film it. The video would probably have been forgotten about entirely had Vitus not recently rediscovered his old digital camera. I decided to show the video to my colleague Heinz Adams, Head of the Production Area (pressing plant/stamping shop) and said: “Look at this Heinz, there’s your Corina”. Later on, he showed the video to his employees and it became a huge hit here at the plant:

Lego experts

The idea for the Lego project came about in the summer of 2006. Vitus, my eldest son, had been on a factory tour as part of a holiday programme at MANN+HUMMEL and was really impressed by the production plants. After this, both of my sons shut themselves away in their room for a whole afternoon and reconstructed the facilities in Lego. The mechanics of the pressing plant alone required a considerable amount of work.


My sons are real experts when it comes to Lego. They have built almost everything, from a medieval castle to a digger. Playmobil and Lego were always a firm favourite when birthdays came around. When children give their creativity free rein, sometimes you even end up with something like a production line. They had so much fun with the project that a few weeks later we had six pressing plants and at least ten of these production lines in the house. And being a long-standing MANN+HUMMEL stalwart, this was a great experience for me.
