automated wire production

Field-proven high-speed braiders built by Niehoff

More than a century of experience Körting Nachf W Steeger has been manufacturing braiding machines for more than a century. Steeger has been working together with medical technology and microelectronics for more than 30 years – sectors where great importance is attached to precision and fineness. The constant co-operation with leading companies of this branch led to the development of exper- tise, which enables them to deal with nearly all braiding-related matters. It is possible to process wires from a diameter of 0.011mm on Steeger braiding machines. The design of the machine in horizontal or vertical construction enables braiding around of bending resistant components as is required. Steeger plaiting machines for the fine wire area are available with all saleable numbers of carriers of 3 - 4 - 6 - 8 etc up to 288 carriers.

More than five years ago, Niehoff started the construction of the BMV12, BMV16 and BMV24 high-speed braiding machines. The machines are designed for 12, 16 and 24 braiding bobbins respectively and can process bare or coated copper wire, alumi- nium wire and stainless steel wire with diameters ranging from 0.05-0.3mm, as well as artificial yarn and fibres. The main purpose usually is to apply a braided shield of fine and superfine wires to data cables, coaxial cables and conductor ropes, and to produce braided wires. Other applications include mechanical reinforce- ment for high-pressure hoses constructions and production of medical catheters. The BMV braider features an infinite variable electronic control of the line speed and the braiding pitch, freely adjusted, and an automatic central lubrication system. Optionally a taping device can be added for the application of metallic or fabric tape on the cable core after braiding. Another option is an integrated low wire on bobbin

detection device which automatically stops the machine before a bobbin gets empty. There are also motor-driven take-ups and pay-offs for space-saving installation under the machine. For bobbins with a flange diameter bigger than 1,000mm, the machines can be equipped with separate motor driven take-ups and pay-offs. Together with the Niehoff winding machines system Hacoba, which transfers wire from larger packages of single and multi-wire spools onto the smaller braiding bobbins, the BMV high-speed braiding machines complete the Niehoff machinery range.

Electronically driven looms The Trinca company has developed completely electronically driven looms for weaving technical fabrics. These looms are equipped with the Trinca patented bandrapier weft insertion system and the patented electronically controlled dobby. Trinca also currently makes electronically controlled shuttle looms featuring servomotor-driven shuttle picking systems, loom functions, synchronised and controlled via PC and up to 10 separately tension-controlled warp beams. Also offered by Trinca are pre-assembled, electronically driven conversion kits for rebuilding existing mechanically driven looms by converting them into electronically controlled machines. The Trinca manufacturing programme includes complete PC-controlled and servomotor-driven weaving looms for metal wire and synthetic yarn fabrics. The company’s loom line includes the type TNE/F for fine wires or yarns; the type TNE/M for middle heavy wire or yarns; the type TNE/P for heavy wires, yarns or fabrics; and the TN2E/PS for very heavy wires, yarns, fabrics and wire cloth. The weaving widths for these looms range from 300-13,000 mm (12" to 512"), with additional width available on request. Suitable for weaving stainless steel, high-tensile carbon steel, high-content alloys, copper, brass, aluminium and synthetic and monofilament yarns, these machines process wires in diameters ranging from 0.03 to over 8mm (0.001" to over 0.3") with warp tension range of 1,500 to 100,000 N/m (100 to 6,860lbf/ft). Specific applications for these machines include: high quality filters, metal wire fabrics for special applications, transport belts, architectural fabrics and external and internal decorative metal fabrics.
