The Legi-Air 4050 CWS label applicator with corner-wrap stamp is suitable for the processing and clean application of labels made of extremely flexible, soft material, for example PE labels. The labeller attaches the labels, which can be up to 400 mm long, to the packaging precisely and cleanly without creating folds. Even around corners. Thanks to the special applicator, the labels can be placed around corners with different length ratios, e.g. 1:1, 1:3 or 2:3. Labels of different lengths can be processed without tools, and without format-dependent interchangeable parts.
