Boockmann will present their HELICORD® technology for wire and cable surface processing and welding wire finishing as well as HELILUB® technology for precision solvent-free lubrication of magnet wire. The HELICORD® principle is based on friction between a fast-moving wire and a textile cord wound around a wire, strand or insulated cable multiple times, moving rather slowly under push-pull-controlled conditions.

This creates a multiple 360° contact between a constantly renewed cleaning or coating medium (i. e. the cord) and the wire. Since friction energy per wire surface unit and thus the cleaning efficiency are independent of the wire speed HELICORD® can be run at drawing speeds. Successful industrial applications are misprint removal from cable, removal of drawing lubricants and metal particles from e.g. strands for high frequency and submarine cables before extrusion, and welding wire finishing with simultaneous coating and removal of particles and drawing lubricant residues.
