THE most recent innovation of
Niehoff’s BMV type series of rotary
braiding machines is the BMI 124
model. The striking feature of this
24-spool machine is its inclined
braiding rotor. The inclination means a
cable deflection of just 45° (instead of
90°) on each deflection pulley,
resulting in reduced cable deformation
and improved braiding quality.
If a caterpillar haul-off is used, the
machine can be applied to
manufacture cables with diameters up
to 40mm. Like the other four models in
the BMV series, which are designed for
12, 16 or 24 spools in vertical
operation, the BMI 124 also offers
infinitely variable electronic control of
the braiding speed and pitch and an
automatic central lubrication system.
The BMI 124 also features fully
automatic electrohydraulic slideway
lubrication. The BMI 124 enables
bundles of braiding wire to be
produced with maximum bundle
cross-sections of 24 x 1.5mm².
All process steps, from the pay-off of
the cable to be braided to the
individual wires and bundles of wires
and the final take-up of the braided
cable, are monitored by a quality
control system. An empty bobbin
detection system can also be installed
which ensures that the machine is
stopped automatically before a
braiding bobbin is completely empty.
This system minimises waste and the
amount of residual wire left on the
bobbin. For greater operational safety
and reliability, the temperature of
slideways is overseen by a monitoring
system. The operator can use this
system for adjusting the lubrication
frequency and amount of lubricant to
optimise lubricant consumption. BMV
machines can be operated for a long
time without an operator.
The vertical BMV machines can be
combined with different types of taping
systems so that braiding and taping
can be performed in a single operation.
This simplifies the manufacturing
process, reduces the amount of space
required and increases the product
quality compared with using individual
process steps.
The experience of many cable
manufacturers has shown that one
BMV machine can replace two or three
older types of braiding machine. The
mentioned braiders can be used for
the processing of bare or coated round
and flat wire made of copper,
aluminium and stainless steel with
single-wire diameters of 0.05 to
0.3mm, as well as yarns and fibres
made of plastic.
The machines can be used for the
production of data cables, control
cables and coaxial cables as well as
for braiding for battery cables, strand
braids and for mechanical
reinforcement for pressure hoses.
