As cables must meet ever more
demanding tasks, cable design is
continually becoming more and more
complex.
Maschinenfabrik Niehoff produces a
range of machines to meet exacting
requirements, for example the DSI double
twist stranding machines and the lever
arm rotary braiding machines of the BMV
series with their taping devices.
Niehoff developed both the data and
special cable stranding machines of the
DSI series with ancillary equipment and
the BMV type braiding machines. The
DSI stranding concept is based on the
successful design of Niehoff’s D series
double-twist bunching machines, which
represents a well-established experience
in the design of wire bunching and
cable stranding machines dating back to
the early 1970s. Similarly the BMV type
braiding system has been developed
by specialists with a long-standing
experience in building this type of
machinery.
The field proven double twist stranding
machines of the DSI series, DSI 631 and
DSI 1001, are designed to manufacture
insulated conductors into pairs or quads
or to strand conductor pairs into special
cables with or without foils. With diverse
components the DSI machines can be
configured into complete lines, perfectly
adapted to the requirements of the users.
Depending on the configuration, a DSI
stranding line can apply up to three foils
inline on a cable under controlled foil
tension in the multi taping process. One
of the several DSI application examples
is the manufacturing of instrumentation
cables for the petrochemical industry.
During the stranding process, the inner
part of the cable has to be covered with
three film layers.
All elements of the cable are assembled
in one process on a stranding line which
is composed by three tangential pay-offs
type ATP 630, three longitudinal tape
pay-offs type ALB 600, a pre-twister type
VVD 180, and a DSI 631 type double twist
stranding machine.
The 12, 16 and 24-carrier lever arm rotary
braiding machines of the BMV series
are mainly designed to apply an EMC
shielding onto cables. With an integrated
central taping device, the braiding and
the subsequent taping processes are
completed in one step under constant
and uniform haul-off tension. In this case,
considerable cost savings result from
eliminating intermediate rewinding and
WIP storage, from requiring less shop
floor space and from a higher product
quality. The applications of the BMV
machines include the manufacture of
data, control and coaxial cables, hollow
braids for battery cables, stranded braids,
and mechanical reinforcements for
pressure hoses and medical catheters.
The BMV braiders and the DSI machines
with their ancillary equipment are part
of the modular Niehoff machinery
programme which covers all operational
steps from rod wire drawing to fine wire
drawing and to data and special cables
manufacturing.
By means of several quality control
systems BMV braiders can work for a
long time unattended and without
operator intervention. With DSI lines all
types of the above-mentioned cables
– and even cables of future categories –
can be manufactured with high speeds
and the utmost precision and quality.
Another advantage for the users of
Niehoff systems is that Niehoff supports
customers with comprehensive process
knowledge, reliable technical assistance
and a worldwide customer service, which
is always ready for action. The users of
Niehoff technology therefore have the
ideal tools at hand to benefit from the
further development in the cable sector.

Beta LaserMike’s new three-axis
LN3015 Lump and Neckdown Detector
is designed to help wire and cable
manufacturers precisely detect
short-term faults in the diameter of cable.
The LN3015 offers a higher degree
of coverage around the product’s
circumference to instantly detect sudden
changes in the surface.
The LN Detector can measure products
up to 15mm (0.59") in diameter at line
speeds up to 3,000m/min (9,842 ft/min).
It can accept a range of inputs including
length encoder, tachometer, line start/stop,
and clear faults and can be connected to a
host PC or PLC using Ethernet IP, Devicenet,
Profibus and Profinet.
Data capture capabilities enable
reporting of critical process information
such as height, length, number and
location of the flaw.
