❍ ❍ Stranding machine

Planetary strander upgrade Leoni elocab GmbH in Georgensgmünd, Germany, in cooperation with Baremo, Switzerland, recently required an upgrade of a planetary strander with variable reverse rotation. As a part of the upgrade project, an RTM X42 telemetry system for continuous wire tension measurement and control was installed on the machine. The basic module measures the tension of up to 42 individual wires. The control centre monitors limit values, recipe management and quality protocols, and the brake control provides continuous, fully automatic wire tension.

The machine is an 18-spool Niehaus planetary strander with two cages of six and 12 payoffs each. Leoni elocab 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 in small production lots (from 100m in length). Klaus Falkenberg, a process engineer at Leoni elocab GmbH, commented, “The project went to our entire satisfaction ... the cooperation with Baremo as well as FMS was target-oriented and professional. We are very satisfied with the results and the set goals of the project have been achieved.”

The project increased plant productivity and process reliability through continuous production without manual intervention in the control of the strand tension. It also provided efficient measuring and control for very small wire tensions in the range from 2N to 20N, with recipe management for reduced set-up times. Measurement data is captured for quality control, and machine safety is increased by monitoring the locks on all cradles. FMS Force Measuring Systems AG www.fms-ag.ch
