Drop wires – Construma

Drop wires are a vital and important part of the weaving process. They make it possible to easy detect yarn rupture.

Our dropwires are made from hardened high grade steel. To ensure high resistance against wear and improved sliding qualities the dropwires are zinc or nickel plated. Every single drop wire goes thorough an inspection to make sure that the drop wire’s edges are well rounded and its surface is smoothly dressed cut.
