Main characteristics

High-precision taping and sealing machines specifically designed for the production of TWINAXIAL CABLES with low-loss and high transmission speed rate. These wire wrapping lines meet the requirements for the production of cables used in Data link layer, SFP+, Ethernet, SATA, Display- Port, etc.

The wire taping modules, linked electrically with the double wheel capstan and served by high precision cable pay-off units, assure the perfect wrapping of the cores, also coupled with the drain wire, with the application of the screening and the sealing tapes.
The precision and the consistency of the final cable are obtained thanks to the fully electronic wrapping heads equipped with WTM’s patented DYNAMIC dancer. The equipment has been designed for guaranteeing  the most accurate tension control of both wires and tapes, despite the non-regular shape of the cable.

These cable taping machines are equipped with in-line ovens to be placed and set according the final product requests. Moreover, a longitudinal taper can be added.
A comprehensive quality control system by means of lasergauges, VISIO SYSTEM® (by camera) and load cells can be integrated in the line, adding the possibility of data collecting in order to manage a complete final product certification.

WTM supports the Customers in the choice of the correct solutions, according to their specific production needs, in the wide range of different TWINAXIAL cable constructions.
