The machine is an 18-spool Niehaus planetary strander with two cages of 6 and 12 payoffs each. Leoni elocab GmbH had previously updated various areas of the machine, and in particular equipped it with a modern control system. The machine is used for the production of highly flexible special cables, some of them of small production lots (from 100m in length).

As a part of the upgrade project, an RTM X42 telemetry system for continuous wire tension measurement and control was installed to the machine.

  • Basic module: Measurement of the wire tension of up to 42 individual wires.
  • Control center: Display, monitoring of limit values, recipe management, quality protocols.
  • Brake control: Continuous, fully automatic wire tension control.

Herewith the objectives of the upgrade were fully achieved:

  • Increased plant productivity and process reliability through continuous production without manual intervention in the control of the strand tension.
  • Efficient measuring and control system for very small wire tensions in the range from 2N to 20N
  • Recipe management for reduced set-up times
  • Measurement data acquisition for quality data acquisition and control
  • Increased machine safety by monitoring the cradle locks on all cradles
  • Simple operation for machine operators and auxiliary staff
