New generation of electrostatic powder
coating machines
Rolf Schlicht GmbH, Hamburg, has more than 30 years’ experience in the design and
manufacture of powder coating machines, especially for the cable
industry.
The electrostatic powder coating machines are
designed for an absolutely dust-free and fine
adjustable powdering of cables and wires from
1-150mm diameter at any speed.
The product is evenly covered with powder all
around the circumference. The electrostatic
charging not only generates a very even
distribution of the powder on the surface,
but also a strong adhesion on the product.
A special and maintenance-free filter system
provides a dust-free operation.
The machine can be adapted to all product
diameters, line speeds and costumers’
needs, and a reproducible and even
powdering at different line speeds and
diameters is achieved by the possibility
to adjust the powder quantity, dust cloud
speed and electrostatic height.
Machines can be provided with one, two or
three electrostatic powder guns, depending on
the speed and product to be powdered.
The company can also provide a free-
standing dust chamber with 3m long
connection hoses.

Wuxi City Yanqiao Cable Accessories Co Ltd, China, produces a range of products
for the wire and cable industry, including a hot-shrinkage cable sealing cap that
features a shrinkage ratio up to 50% (radial), and is air-tight, moisture preventing
and leak proof.
The company’s cable marking ink ribbon is suitable for printing all kinds of cable,
plastic pipe and wire with uniform coating, legible and durable print and three
colours – white, yellow and black. Its length and width can be cut according
to users’ needs, and the hot printing temperature is approximately 80ºC.
The company’s hot shrinkage cable core pipe is suitable for connecting
communication cable core with good insulation protection effect. It may also be
used in the electronics industry, household appliances and power companies,
due to its insulation and anti-flaming effect, and only requires an electric heating
dryer for shrinkage.
Other products from Wuxi City Yanqiao Cable Accessories include PE film, hot
shrinkage protection sleeve and cable branch sleeve, cable head iron protecting
cover, self-adhesive rubber strip, and a hot shrinkage wrapping tape designed for
sealing and remedying the connection and breakage of embedded or overhead
steel pipes and plastic pipes, and for the protection of weld joints, corrosion
prevention and insulated pipes.

Niehoff pointing
to the future
Maschinenfabrik Niehoff has
developed production equipment
which reliably covers most steps of
automotive, data, LAN and special
cables manufacturing.
An outstanding example are the BMV
type high-speed braiding machines
which are usually used to apply a
braided shield of fine and superfine
wires to data cables, coaxial cables and
conductor ropes.
The machines are designed for 12,
16 and 24 braiding bobbins respec-
tively and can process bare or coated
copper wire, aluminium wire and
stainless steel wire with diameters
ranging from 0.05-0.3mm, as well as
artificial yarn and fibres.
Among the characteristics is an
infinite variable electronic control
of the line speed and the braiding
pitch, and an automatic central
lubrication system. Optionally a
central taping device can be added
for the application of metallic, plastic
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 integrated in the
frame of the machine.
For reels with a flange diameter
bigger than 1,000mm, the machines
can be equipped with separate motor
driven take-ups and pay-offs.
The BMV machines can unfold their
full potential when using the semi-
automatic and automatic ‘Niehoff
winding machines system Hacoba’,
which transfer wire from larger
packages of single and multi-wire
spools onto the smaller braiding
bobbins.
The high quality package allows
these bobbins to be processed
into the braiding process at high
braiding speeds with no wire
break rates.
