Print-Apply Labeling System

Legi-Air 4050E

Energy-efficient all-rounder for high-speed applications with a wide range of expansion options

  • Reduced compressed air consumption and low wear
  • Large selection of applicators, tamps and print modules
  • Industry 4.0-capable
  • Dispensing cycle rate up to 240 labels/min
  • Achieves print speeds of up to 400 mm/s
  • Label size min. 12.5 x 7 mm, max. 160 x 210 mm

1,500 applicator variants for all positions and formats

The Legi-Air 4050E is a rugged, compact print-&-apply labeler with a wide range of expansion options. Thanks to a consistently modular design and more than 1,500 applicator variants, the system can be tailored to your specific application. The many available and very robust applicators support any labeling position and speed. Print engines from all leading manufacturers are available for printing the labels.

The print-&-apply system is designed with no scheduled-wear maintenance parts. Components are replaced only as needed. The installed print engine must be serviced in accordance with the respective manufacturer’s specifications.

If required, a bad-tag reject arm is available to automatically eject faulty labels and remove them from the conveyor line. A protective enclosure for integration into production environments with high dust loads, moisture, and/or low temperatures is also available.

Special features

Legi-Air 4050E reduced compressed air consumption

Reduced compressed air consumption and low wear

The modulated vacuum reduces compressed air consumption by up to 80 % and integrated sensors permanently measure the pressure. If necessary, the valve technology adjusts. The pneumatics are easily accessible outside the system and the two compressed air circuits are colour-coded for better differentiation. The motorised operation of the winder and unwinder means that the integrated print module wears less, while at the same time the prints are extremely precise.

Legi-Air 4050E applicators

Over 1500 applicators for every label size and position

Whether single-sided, double-sided or corner wrap application - a wide range of applicators and tamps are available for applying labels to products, packaging and pallets. Single-sided pallet labeling with an extra-long dispensing stroke or the labeling of uneven product surfaces is also possible. The Quick Change option is available for a very quick change to a different label size.

Legi-Air 4050 display

Convenient handling via touch display

The Legi-Air 4050E is easy to operate via the multilingual 7" LCD touch display. Fault diagnostics, productivity, maintenance status and events can also be viewed.

Legi-Air 4050E print modules

Modular print module concept including RFID

The print & apply labeling system can be combined in all variants with a wide range of print modules from well-known manufacturers. Replacing one print module with another is possible at any time without difficulty. For programming and printing smart labels, an RFID print module is available. This supports all current RFID standards (UHF).

Industry 4.0 capability

Legi-Air 4050E is optionally available with an additional N-Controller. This is OPC UA-capable (Open Platform Communications United Architecture). This Industry 4.0 interface enables an extended connection with other devices and the exchange of information that goes beyond simple signals.
