The output of highly complex nappy production lines at Ontex Mayen has tripled over the past few years without any investment in new machines. This has been made possible by ensuring that the production line runs with virtually no downtime, as well as to continual improvements made on the production process. In addition, set-up times have been reduced significantly. The necessary flexibility when changing to different formats is guaranteed by various linear bearings from igus, which fulfil all manufacturing requirements. The drylin bearings are designed to operate in rough and dirty conditions, working 24 hours a day, 365 days per year.
