  • Achieves print speeds of up to 400 mm/s
  • Label size min. 50 x 40 mm, max. 120 x 200 mm

Energy-saving, high-performance label print applicator

With up to 2,400 products per hour, the Legi-Air 6000 high-speed labeler labels cartons of different heights on the conveyor belt that throughfeeds particularly quickly. Product height differences of up to 500 mm are possible. Once a sensor has determined the height of the product to be labeled, the electric applicator moves into the correct position. As a result, the travel distance during the labeling process is shorter, while at the same time the label print applicator dispenses labels more accurately and up to 50 percent faster than a labeler with a pneumatically operated cylinder. This is supported by the consistent lightweight construction with carbon fibre components for the moving parts. The applicator is around 80 per cent lighter than a conventional model.

Control is optimised in terms of cost and space by a microprocessor controller. There is no need for a separate control cabinet, so the compact device can be easily integrated into production environments. The modular design allows a high degree of customisation and easy integration into existing production lines.

Special features

High range, low maintenance

The Legi-Air 6000 is designed for use with large rolls up to 350 mm in diameter. This size corresponds to a label supply of about 600 meters, allowing long operating times without interruption. The high capacity significantly increases system availability, as roll changes are required less frequently. At the same time, maintenance times are reduced, and the entire production benefits from a more reliable process.

Electric applicator reduces compressed air consumption

The applicator of the Legi-Air 6000 operates servo-electrically and does not require permanent compressed air. This not only lowers operating costs but also saves energy and reduces the maintenance effort often associated with compressed air systems. Only during the tamp-blow process, i.e., when applying the label onto the product, is a small amount of compressed air used, maintaining the overall efficiency of the system.

Simplified maintenance

For particularly user-friendly operation, all relevant system components are easily accessible. This makes routine tasks such as cleaning, foil, or label changes much easier. In case of a malfunction, the applicator automatically moves into a service position above the print head. This allows the operating staff to intervene without great effort, minimizing downtime and ensuring the system’s productivity.
