Cleaning in-line

Boockmann’s Helicord technology, based on a push-pull controlled textile cord wrapped around a wire or cable, has been successful in various applications in cleaning round wire, strands and insulated cables as well as in applying different types of additives, such as corrosion inhibitors, strip aids and adhesion enhancers.

Helicord cleaning in operation ❍ ❍

The cord is continuously fed into the process area of the machine, with the cord speed being adjusted to the speed of the production line, thus wiping off impurities or distributing liquids evenly on the surface. Cleaning can be done by a dry cord, or supported by solvents or other cleaning liquids. A frequent application is cleaning the copper tube used for power supply in optical cables after welding and final drawing, in order to remove drawing lubricant residues and metal particles, and to improve adhesion between the copper and insulation. The main advantages of Helicord, compared to other cleaning technologies, are: Multiple 360° contact between the cable and cleaning medium • The cleaning medium is constantly refreshed • The process is independent from production speed • Standard Helicord machines are currently capable of treating diameters up to 20mm; larger diameters require customised modifications of the machine.
