WTM’S innovations through the years

Dancers are also eliminated from these lines with the aim of reducing the quantity of surfaces in contact with the cable, and even devices that help to avoid curving the cables through the production process are employed.

Since forming, WTM has always had customer satisfaction as its main target. This has meant listening and understanding the different production needs and designing the equipment with the aim of offering the best and the most advanced technological solution. Together with the evolution of the cable industry, WTM has achieved a very high technical and technological level with its machines, in different fields of tape application and treatment. The taping lines for the insulation with polyimide and PTFE tapes have been integrated with sintering (sealing) systems developing the technology of salt bath ovens in addition to the traditional IR light and resistors ovens. The taping machines, in particular those with horizontal layout, are put in line with induction pre-heaters, if requested, then ovens, with fully automatic opening and closing movements during start-stop phases. Subsequently, the layer is consolidated by compacting units and cooling equipment. WTM offers the treatment of multiple wires, including with different diameters, to obtain final products of very high quality. Knowing all the problems and criticality of coaxial cables, WTM has designed lines that treat such cables with extreme delicacy, through the elimination of vibration sources and of repetitive errors/noises. Competitive advantage through radio-based wire tension control With its radio-based RTM X42-series and a wide range of force measuring rollers, FMS offers innovative, trend-setting systems for wire tension control in stranding machines. Since its first introduction two years ago, RTM X42 has evolved from a pure tension monitoring device to a multi-purpose control and analysis system. Its ingenious interface concept has been expanded to now provide recipe controlled operation and the processing of encoder signals. The product family is offered in four different basic versions. A sensible combination of these versions is possible. • RTM X42.IO: With analogue outputs for controlling capability via a PLC • RTM X42.PC: Tension monitoring with data processing and analysis capability • RTM X42.MODBUS: Provides a flexible interface concept adapting to any bus system used in the machine. It allows real-time control of breaks or drives • RTM X42.MP: Processing of encoder signals eg for close loop control of drives and the control of the traverse guide in individual bobbins RTM X42 utilises force measurement rollers to capture the tension value of individual wires or strands, and then securely transmits this data from the rotating to the static portion of the machine. This all happens over a radio link and without troublesome slip rings.

The results are cables suitable for extremely high frequencies having good signal transmission and reduced stationery waves.

In the field of the machines for testing cables, WTM produces lines that allows the testing of cables through torsions and bending movements so to submit the production at the most severe international norms. WTM test machines are multi-position, and have the widest possibility of setting: times, rotation angles, speed, cycle numbers, etc. One of the latest and most advanced solutions is the Visio System which has been created for helping cable production with several overlapped tapes wrapped in the same direction with constant displacement. It is now available for many different measurements and for quality control procedures, even on the whole surface of the taped cable.
