In the packaging sector, the production of sturdy cardboard boxes with an impeccable design is crucial to ensure the integrity of products. At the heart of the process is the folding-gluing machine, a highly automated system that must combine high speed with millimetre-level accuracy in the folding and glue application stages. Any geometric misalignment or variation in contact pressure compromises the stability of the box, leading to rejects or line stoppages.
To overcome this challenge, manufacturers rely on solutions that can ensure maximum smoothness and rigidity. The latest-generation bearing systems and linear solutions optimise rotary and translational movements. In folding-gluing machines, the use of profiled guideways controls the complex kinematic forces at play, translating the dynamics of the motors into stable and repeatable positioning over time.
Inside packaging machines, Schaeffler‘s profiled rail systems with recirculating ball or roller bearings perform an irreplaceable task. These linear guideways control the ultra-precise positioning of the folding stations, side barriers and gluing nozzles. Since box sizes often change, the machine must be able to be reconfigured extremely quickly.
The precision profiled guideways ensure smooth movement of the operating units and offer exceptional rigidity, eliminating mechanical play. This structural level prevents vibrations generated by very high speeds from being transmitted to the folding elements or glue applicators, ensuring consistently accurate geometric forming.
The integration of these linear guideways improves packaging quality and production speed. The reduction of internal friction minimises the energy consumption of the machinery. Furthermore, the intrinsic robustness of the advanced surface finishes and integrated sealing systems – which protect the tracks from cardboard dust and glue residues – extend the lubrication intervals. For continuous-cycle box-making plants, this means reducing downtime, optimising the overall efficiency of the plant and ensuring a streamlined production flow.
