For fully automatic cut-to-length and stripping
of cables up to 240mm²

At the start of a large project for high-speed trains, an Chinese manufacutrer was looking for a solution for automatic cable processing. As well as high length accuracy, the company needed a machine that could withstand the demands of processing particularly hard copper cables of up to 240mm² in continuous industrial production.

To increase production and processing quality, the automatic infeed of the cable to the processing machine is a significant element. The cable drums, weighing up to 1000 kg, had to be unwound at high speed but at the same time subjected to low tension to avoid damage to the material. This requirement is handled by the electrically driven „Metzner DR 12.1000“. All the functions, such as for example, the unwinding of the cable, the tensioning of the cable rolls or the raising of the cable rolls are motorised. Most of all, the electrical handling of the heavy cable drums make the whole process more easy.

Precise cut-to-length and processing
The best results in processing the particularly hard copper cables of up to 240mm² were produced by the „Metzner 5300 HD“. With the „Heavy Duty“ version and its related hardened knives, even the thickest copper cables could be cut to length and multi-staged stripped. The required production controls were provided, thanks to the standard system supervision by the machine. Using a series of sensors, the machine monitors the material infeed, stops the production when there is a material blockage and informs the operator about locating the fault.

Winding
For the onward transport of the processed cables, Metzner integrated an automatic cable winder for rapid and effective winding of the cables. With a weight of up to 80 kg per wound spool and an internal diameter of 250-600 mm, the „Metzner CRC 750“ was the right solution.

Marking
For identification of the cables, Metzner integrated a thermal transfer labeller, capable of producing all types of print ( texts, graphics, barcodes) in very high print quality ( 300dpi). The label with all the relevant production data is attached to each cable ring at the end of the winding process, allowing the cable ring to be easily identified during subsequent processing.
