Screening machines for coaxial cables

High-precision taping lines, specifically designed for the production of flexible microwave coaxial cables with low-loss and high phase stability.
The machine covers the requirement for the production of low-loss microwave assemblies used at high frequencies in different applications: aerospace industry, telecommunication technology, aircraft applications, video and computer systems, military equipment, medical systems, etc.
The wrapping module, electrically linked to the combined pulling unit, guarantees the perfect application of the silverplated strip over the insulated core. All this can be achieved thanks to the unique taping process, by means of the fully electronic wrapping head provided with WTM’s patented DYNAMIC dancer.

The line was designed for the most accurate tension control of the wire, keeping it in the correct position and avoiding any bending and stressing of the core during the process.
The control system is fully digital, by electrical axis and field-bus communication. The machine is easily managed by a color touch-screen panel. WTM supports the Customers in the choice of the correct solution according to the specific production need, in the wide range of high frequency coaxial cables.

Details:

• absolute wrapping accuracy with possibility of cable calibration;
