Krones AG - packaging machines
In 2005, Krones faced a challenge with Variopac Pro, a fully automatic all-round packaging system: its performance had to be increased by 20 packs per minute. Hence, there was an urgent need for action during the deflection of the conveyor belts. Originally, metal rollers with needle roller bearings had been in use here, but they couldn't meet the higher performance requirements and were cost-intensive. Looking for an alternative, Krones Design Engineer Jürgen Werner came upon knife edge rollers from igus.
