2006: International trade fair „Draht und Kabel“ in Duesseldorf April 24th to 28th


New at this exhibition: flat Helicords for treating stranded and large-core wire

The flat Helicords have been developed to avoid convergence of loops, and to meet extremely high surface purity requirements, e. g. for welding wire, stranded wire and cables by giving a bigger contact area. They are also applicable for copper clad optical fibers.

The composition of Helicords can be customized to meet different needs.

Demonstration of multi-stage abrasive treatment:

Solid impurities on the wire surface, e. g. powdery drawing agents like calcium stearate or graphite, can easily be removed by abrasive treatment. It requires several Helicord models NB55 and NB56 to be arranged in line.
The demonstration unit was set up of two NB55 devices, the first one using abrasive Helicord, the second one using an absorbing type of cord. Both devices were supplied with a fluid with low surface tension, so that formation of dust was minimized and the cleaning performance was maximized.
