Industry 4.0 concept with braider for medical technology applications

technology products. Via the WTC (wire tension control) system, the machine regulates the braiding wire tension of the braiding bobbins, from full to empty condition. Consequently, all braiding wires are applied under uniform tension to the product to be braided. The braider also keeps the braiding coverage ratio constantly at the pre-set value. With only the necessary braiding wire being applied, Niehoff states that up to 15 per cent of material can be saved, in comparison with conventional braiding machines. The braider can automatically accel- erate the bobbin rotational speed from 175 rpm to 200 rpm while reducing the frequency of the lubrication intervals, resulting in increased braiding output and braids that are less contaminated with oil.

With Niehoff Digital Assistant+, Niehoff’s Industry 4.0 offering, machine, production and process data can be recorded, making continuous process monitoring and machine condition analysis possible. The MSM 83 compact rod breakdown machine with electronic controls is designed to draw rod wire made of copper and copper alloys to a finished diameter range of 1.38 to 4.56mm (0.054" to 0.179"), equipped with 11 drafts. The MSM 83 can operate at speeds up to 38m/s (7,480 fpm) and is available with 11, 13 and 15 drafts. As the drawing capstans are placed on two levels, the MSM 83 is short and can fit into tight spaces. The company’s BMV 16.S vertical lever arm rotary braiding machine is designed for the production of medical

Fillers, ripcords, binders and fibreglass strength elements

Ripcords are twisted, in various colours, from polyester, polyamide, aramid or Vectran. Binder yarns are mainly produced from low-shrink polyester or other fibres. Glass roving, as a strength element for optical cables, is the company’s latest product. All yarns can be applied with water-blocking or non-wicking coatings. The main products of Max Süss are twisted cable fillers. Textile fillers – mostly from polypropylene, cotton,

Founded in 1860 in Germany, the company Max Süss GmbH is looking back on 160 years of history and experience in the production of yarns, twines and ropes. The company is focused on producing industrial yarns for the wire and cable industry. With new investments in machines and equipment during recent years, Max Süss offers a complete portfolio of textile products required by cable manufacturers.

paper or polyester – will be twisted (round or flat shape) to the exact required diameter (±0.1mm) in a range from 0.5 to 8mm. In addition to twisted filler yarns, Max Süss offers multi-ply ropes in diameters from 1.5 to 16mm. Such ropes are mainly used in drag-chain cables and charging cables as fillers and flexible strength elements. All yarns can be supplied on large bobbins, or even on cable drums, without knots or splices. This allows high running lengths and decreases the downtime in production for changing the material. All PP fillers are available in flame-retardant and halogen-free versions. Max Süss GmbH & Co KG www.max-suess.de
