The Legi-Air Twin from Bluhm Systeme, with its two series-connected printing modules, is the answer to meeting the legal requirements of the the European GHS regulation (EC) No. 1272/2008. It labels different sized pallets, folding boxes and especially barrels, in through feed mode, with small and large label sizes, multi-colored and at various customised positions on the containers. Integrated controls support the operator in handling the print modules. Both printing mechanisms are of similar design and intuitive to operate. The applicator systems may, if required, also be controlled and networked via Bluhmware.
Apart from the hazard statements “H” and the precautionary statements “P”, the 2-colored warning symbols are also printed in the required quantities and dimensions, as required. Product designations, quantity information, logos, barcodes (1- or 2-dimensional) are proven technology. In the Legi-Air product family, this basic system also can be combined with a range of standardised and customised applicators.
In developing the Twin, reliable handling of large size labels received particular attention. The Legi-Air Twin is based on the Legi-Air 4050, which is fitted with a special belt applicator adjacent to the second print unit. This is designed so that, with barrel labeling for instance, it adjusts to match the height and diameter of different container sizes automatically. This enables accurate, central labelling away from the seams.
The label is applied using the so-called wipe-on method. The finished label is evenly peeled off the backing paper, held by vacuum and transported to the barrel by conveyor belts. The processing speed can be high, since the printing process is separate from that of label dispensing. It is recommended to turn a cylindrical product during the labeling process if the length of the label exceeds 1/3 of the barrel diameter. The label width and -length depend on the data volume, but this can always be easily adjusted to suit specific customer requirements.
