Braider for medium heavy and heavy cables

One of the most popular machines is the medium heavy braider type Dratex 2450 for cables up to 45mm diameter and copper and steel wires up to 0.4mm diameter. The Dratex 2450 is suited for high-speed production in short and medium run lengths. It also provides the flexibility to move easily from wire applications to textile applications for both cables and hoses. Its smaller space-saving footprint makes it well-suited for multi-product, quick response producers who need flexibility. This braider can handle spools with a maximum flange diameter of 110mm with a capacity of 780cm 3 . Spirka Schnellflechter GmbH – Germany Website : www.spirka-schnellflechter.com
