Print-Apply Labeling System

Legi-Air 4050CWB

Efficient corner wrap application - flexible, compact and tool-free changeover

  • Cross-corner labeling & single-sided labeling without modification
  • Compact design, flexible integration
  • Print speed up to 400 mm/s
  • Print quality up to 600 dpi
  • Tool-free change of label formats
  • Label size min. 50 x 50 mm, max. 150 x 360 mm

Over-corner labeling without modification for maximum flexibility

The CE-compliant Legi-Air 4050CWB is the perfect solution for corner labeling. This is particularly advantageous in block-stored warehouses, as commonly found in the pharmaceutical, food, and drugstore industries. Thanks to its innovative application concept, the system labels cartons across two sides with a single label produced in one printing process – maximum data security included. By using electric linear axes and multi-flex tampers, the labels are gently and precisely applied. Particularly practical: switching to single-side labeling or other corner modes can be done tool-free and without conversion. Even varying product heights and different label formats are handled effortlessly by the 4050CWB. With a printing speed of up to 400 mm/s, positioning accuracy of up to 1.5 mm, and CE compliance without additional protective measures, it offers maximum efficiency, flexibility, and safety – even with challenging label qualities.

Special features

Legi-Air 4050CWB 2-side labeling

Labeling on two sides with one print set

The Legi-Air 4050CWB applies a single label in such a way that it extends across two sides of the product. As a result, the marking remains readable even when only one carton surface is visible. This process ensures absolute information security and is particularly suitable for warehousing and logistics processes where cartons are tightly stacked or only partially visible. In this way, reliable traceability is guaranteed throughout the entire material flow.

Legi-Air 4050CWB electric applicators

Gentle application thanks to EL applicators

The electric strokes of the two EL applicators ensure controlled, gentle pressing of the label onto the product surface. This significantly reduces air turbulence and achieves uniform adhesion. Especially with sensitive or lightweight packaging, this technology ensures gentle handling without damaging the products. At the same time, process reliability is increased and a consistently clean labeling result is guaranteed – even at high cycle rates.

Legi-Air 4050CWB tool-free changeover

Tool-free customisation of label size

With the innovative quick-change adapter, label formats and pitch ratios can be changed in the shortest possible time without additional tools. This not only saves setup time but also increases flexibility in production lines with frequently changing requirements. In this way, different products can be labeled efficiently without having to accept long downtimes. The fast and simple change ensures maximum productivity and smooth processes in operation.

Legi-Air 4050CWB module changeover

No mechanical modification when changing mode

The changeover between different corner labeling combinations, such as front/side or rear/side, as well as to single-side labeling, is carried out completely without mechanical adjustments. This allows production processes to be adapted much more quickly to changing requirements. The tool-free changeover saves valuable setup time, reduces downtime, and at the same time increases flexibility in variable manufacturing environments. In this way, the system always remains efficient and productive in operation.

Legi-Air 4050CWB compact design

Compact design - maximum integration

The Legi-Air 4050CWB stands out for its particularly space-saving design and can be integrated into almost any existing production or packaging line with minimal effort. No additional space or separate safety guards are required, which greatly simplifies installation. This makes the system ideal for environments with limited space and enables smooth integration into existing processes without compromising safety or efficiency.
