Taping and cable production. WTM’s technological innovations through the years

Since its creation, WTM has always had customer satisfaction as main target; this has always 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 cable industry, WTM's experience has been improving, achieving 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/curing) 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 high speed solutions, with possibility of multiple wires treating, also with different diameters, obtaining final products of very high quality.

Knowing all the problems and critical points of coaxial cables, WTM has designed lines that treat such cables with extreme delicacy, through the elimination of vibration sources and repetitive errors/noises. Dancers for cable tension control are also eliminated from this lines, aiming to reduce the quantity of surfaces in contact with the cable; even devices that help avoidind curving the cables through the production process are used. The results are cables suitable for extremely high frequencies having good signal transmission and reduced stationary waves.

One of the latest and most advanced solution is WTM’s VISIO SYSTEM: created to help the 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.
