FEATURE Coding, Labelling & Marking
Labelling cables
Human beings have been wiring the world since the late 19th century. Cables, whether installed on a permanent basis or in flexible use, regulate electrical goods and electronics, telecommunication services, and industrial and home technology, among others. By marking them reliably with labels, data streams, network and voice communication are assured. Handwritten notes have long since ceased to meet the highest standards. Regulations require, for example, data readable by machines, encoding, resistances and protection from manipulation. Guntram Stadelmann, Technical Editor, Cab Marketing, explains

ables can be labelled in many ways, depending on the application, with the labels indicating types
or performance, flagging or shrink tubing. Particularly in the automotive, chemical and pharmaceutical industries, liquids, where solvents and chemicals are widely used and mechanical wear is a major factor, markings are exposed to varying and often abrasive conditions. Here, customers benefit from Cab’s long-term experience. Its thermal transfer printers offer printable resolutions to 600dpi, and high-contrast and sharp-edge print images even in marginal areas. So, even tiny fonts can easily be read and micro barcodes verified by scanners. Provided that proper labels and ribbon materials have been used, thermal print images remain legible during processing, testing, storage and transport.

tolerance systems are required. Devices of the HERMES Q series are capable of this with labels as small as 3 x 4 mm. Labels intended to be processed automatically by a Cab flag applicator are then optimised. Serial numbers or barcodes can be printed on labels, which are then folded around cables.
Sealing labels are protected from manipulation, from tearing or removal, by leaving emblems on a surface, being no longer fully transferable.
Wrap-around labels
In addition to identification, such labels also perform protective tasks. Instructions for use or other short texts on a label can be preserved with the help of a protective foil. Cab is currently developing a special applicator, to be assembled to a SQUIX label printer in case of applying wrap-around labels onto cylindrical items such as single wires, strands, cables, hoses and round rods.
Shrink tubes Shrink tubes are widely used in electrical cabinets and automation. The plastic tubes contract under heat, and the objects wrapped by shrink-tubes are electrically insulated. Labelling allows reliable identification and classification. Cab provides printers designed for shrink-tube labelling with centred material guidance. The XD4T printer model has been designed for double- sided printing, with two print heads being assembled head-to-head on the device. Electrostatic charge is derived after printing, using a brush. When printing at high heating energy, a separator enables reliable processes by preventing the thermal transfer ribbon from sticking to the material. An additional roller keeps the material tensile.
