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.

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.

Field-proven high-speed braiders
built by Niehoff
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.
