The volumetric Miniblend V dosing and mixing unit offers
excellent mixing quality and consistently accurate dosing.
Mounted between the machine hopper and the feed throat
of the plastics processing machine, the unit requires very little
space.
Disc dosing with the Miniblend V
gives real volume dosing which
guarantees a very high dosing
accuracy – even for very small
dosing quantities.
Three different disc sizes as well as
dosing modules made of materials
such as stainless steel or glass,
and special wear-resistant discs
for hard and abrasive materials
are available. Module exchange is
quick and easy and thus allows fast
colour changes.
The Miniblend V is designed to
dose free and normal-flowing
materials and micro-batches.
The unit can be operated by motan’s
volumetric controls VOLU MC or
VOLUnet MC, which is equipped
with an Ethernet interface.

As cable products have to meet continuously increasing
demands, wire and cable manufacturers need machinery
which enables an energy-, raw materials- and cost-effective
manufacturing process. Furthermore, the machines must
be flexibly adaptable to new production requirements. The
machinery developed and built by Maschinenfabrik Niehoff
meets all these requirements. One example is the lever arm
rotary braiding machines of the BMV series, designed for 12, 16
or 24 spools in vertical operation.
The BMV machines feature an infinitely variable electronic
control of braiding speed and pitch as well as an automatic
central lubrication system. 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. As an option, an empty bobbin
detection system can be installed which ensures that a BMV
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 monitored by a monitoring system. The operator
can use this system for adjusting the lubrication frequency and
amount of lubricant to optimise lubricant consumption. As a
result of all these measures, BMV braiders can be operated for a
long time unattended and without an operator. The most recent
innovation in the field of the BMV braiders is the 24-carrier lever
arm rotary braiding machine BMI 124. A striking feature of the
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 combined with a caterpuller
haul-off, the machine can be used to manufacture cables with
diameters up to 40mm. The BMI 124 enables bundles of braiding
wire to be produced with maximum bundle cross-sections of
24 x 1.5mm².
The 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 when individual process steps are used.
The experience of many cable manufacturers has shown that
one BMV braider can be used to replace two to three older
types of braiding machine. Niehoff’s BMV braiding machines are
designed 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, braiding for battery
cables, strand braids and for mechanical reinforcement for
pressure hoses.
