Legi-Air 2050

Low-Cost Print Apply System: easy to integrate - easy to operate!

The compact Legi-Air 2050 label print and apply system designed for automated print and apply processes in production lines. It can also be used in semi-automatic mode, where automatic label application is not required, the system can be used as a label print and dispense system, with label application by the operator manually.

Contactless labelling of varying heights

The robust system offers maximum performance with a small compact footprint with a highly efficient low energy tamp blow applicator for contactless labelling.

The variable stroke provides for automatic labelling of products of varying heights. The system permanently ensures that the labels are in the correct position before being blown onto the product.

Application rates of 25 labels per minute with a label format of 80 x 60 mm can be achieved without any problems. Higher dispenser speeds can be achieved, depending on the label material, format, and application.

Legi-Air 2050: a reliable work horse

The Legi-Air 2050 is a compact reliable work horse, its robust applicator with Festo pneumatics and recirculating ball bearing system provides a durable composite design and guarantees labelling accuracy during the print apply process. In order to reduce reel change times, the labeller comes out ahead of alternatives in the market: It handles larger label rolls – with an outer diameter of 218 mm – and therefore applies an average of 20 percent more labels therefore reducing reel change downtime.

The print ribbon length of 600 mtrs ensures that the labeller can perform continuous label printing over longer periods of time. If the ribbon or labels have to be changed, this is done quickly and easily due to the modular design and ease of access to the printer mechanism.

Printing without compromise

The printer used is a SATO of the CLNX series with 300 dpi resolution. The printer works with many programming languages such as ZPL, DPL, IPL, and TPL without having to change any settings. Printer Errors are easily diagnosed with the messaging system on the printer panel, the user can view a video on the printer display, showing how the error can be corrected. The labeller prints small labels from 40 x 30 mm up to labels in DIN A6 format and bigger and then applies them in their precise position.
