On Print and Apply Systems it is often the print module which determines the working rate. This is not the case with the new Legi-Air 4050 AC Shuttle.

 

A loop device ensures a ready supply of labels which are custom-printed before being dispensed at unusually high speeds onto the passing products. The capacity of this storage device means that even higher cycle speeds of short duration can be achieved. A check is kept on the loop by a dancer roller to ensure there is a supply of labels present. The benefits of this variant are

ease of use and the compact system design. Labelling capacity may be up to 20 times greater than printing capacity. Print speeds of up to 16 m per minute and conveyor speeds of up to 70 m per minute can be achieved.

Typical applications are labelling of identical products or products of continuous height. Compressed air is not required unlike most systems in the market today as the Print Apply System is completely electric and virtually Plug and Play. The result is a high level of cost-efficiency.

For partial printing on the label, print modules with automatic Ribbon Saver systems are available, resulting in further cost savings.
