Print-Apply Labeling System

Legi-E 4050AC

High-speed labeling - flexible, precise and completely electric

  • Electric operation - no compressed air required
  • Dispensing cycle rate up to 600 labels/min
  • Label liner buffer for uninterrupted work
  • Wipe-on dispensing process - gentle application in a throughfeed
  • Compact design, simple integration
  • Label size min. 14 x 20 mm, max. 148 x 210 mm

Faster labeling thanks to label liner buffer

The Legi-E 4050AC is the perfect solution for anyone who wants to combine maximum labeling speed with maximum precision. A label liner buffer allows printed labels to be stored temporarily so that they can be dispensed onto products at up to 50 m/min - regardless of the print module cycle. Various dispenser modules are available for the Legi-E 4050AC, with a pusher roller or brush on request. This ensures that all types of labels adhere securely. Perfect for labeling cartons and outer packaging on the top or side.

The Legi-E 4050AC works completely without compressed air, which saves operating costs and minimises maintenance. The compact design and easy handling make it ideal for a wide range of production environments. Thanks to the wipe-on dispensing process, labels are applied gently and accurately - even when conveyor speed change or the conveying system stops briefly. Automatic calibration to the relevant format saves time and prevents mislabeling.

Special features

Two speeds for maximum performance

The integrated label liner buffer allows the printing and dispensing processes to be decoupled and run at different speeds. This ensures smooth label application at all times, even when production cycle rates change. This principle provides maximum flexibility, prevents workflow jams, and guarantees consistently high process reliability under varying requirements.

100 % electric - without compressed air

The Legi-E 4050AC requires no compressed air, operating fully electrically. This significantly reduces ongoing operating costs, as no expensive compressed air systems are needed, while also making installation much easier. In addition, energy consumption in production is reduced, making overall processes not only more efficient but also more sustainable. This makes the device a future-proof solution.

Precise positioning for every cycle

An integrated shaft encoder ensures that labels are placed with absolute accuracy at every cycle, regardless of changing conveyor speeds or sudden line stoppages. Misalignments are reliably avoided, ensuring consistently high labeling quality. This precision not only guarantees a clean appearance but also process stability and reduced waste during operation.

Compact design and easy integration

Thanks to its compact and well-thought-out design, the Legi-E 4050AC requires very little space in the production environment. It can be easily integrated into existing lines without major conversions or adjustments. This makes it an ideal solution for modern, automated manufacturing processes where efficiency, space savings, and smooth interaction with other equipment are essential.

Touch display

The current device generation of the Legi-E 4050AC features a modern touch display that makes operation particularly simple and intuitive. Settings can be made, processes monitored, and error messages quickly identified via the user interface. This not only makes daily handling more convenient but also increases operational efficiency, as operators can react immediately and optimize production flow.
