Print-Apply Labeling System

Legi-Air 4050I

Energy-efficient all-rounder with maximum protection and a wide range of expansion options

  • Protection from dust, heat and cold
  • Stop valve protects applicator
  • Label size min. 12.7 x 7 mm, max. 150 x 210 mm
  • Achieves print speeds of up to 400 mm/s
  • Dispensing cycle rate up to 75 labels/min
  • Reduced compressed air consumption and low wear

Extremely adaptable to harsh industrial environments

The Legi-Air 4050I label print applicator with stainless steel protective housing is particularly robust. It is housed in a sturdy protective cabinet that protects against dust, cold and heat and enables reliable labeling, especially in demanding industrial environments. Climate control solutions such as pressurisation kits, heating or cooling are optionally available. A stop valve, which prevents the applicator from dropping unintentionally, ensures maximum safety. Different applicators are available depending on the application.

Applications

2-colour hazardous substance label on metal drum
Label on paper sack
2-colour hazardous substance label on drum

Special features

Modular safety storage cabinet

The integrated protective cabinet reliably shields the labeling system from external influences such as dust, heat, and cold, ensuring consistent performance. This extends the system’s service life and significantly reduces the likelihood of failures, even under demanding production conditions.

Vision systems can be used flexibly

Scanners or vision systems can be flexibly and precisely deployed as needed. They can be mounted directly on the tamp pad to check labels immediately during application or installed statically on the conveyor to continuously monitor the process. This versatility makes it possible to meet different quality and safety requirements, detect errors at an early stage, and sustainably optimize the entire labeling process.

Dual compressed air supply.

The compressed air supply is intelligently divided to provide greater operational efficiency. The first inlet controls label handling, vacuum, air-assist function, and blow-off. The second inlet is dedicated to actuators, such as cylinder movements. This separation ensures a stable and powerful supply, enabling more precise control and longer component life.

Electric winders and unwinders

The electrically driven rewinders and unwinders play a key role in protecting the integrated print module by minimizing mechanical stress. Motorized operation ensures smoother label feed, resulting in exceptionally high print precision. At the same time, process reliability is improved by reducing fluctuations. This guarantees consistent print quality and overall higher reliability in ongoing production.
