Verseilmaschinenbau’s
products
embrace a wide range of machines and
equipment for the manufacture of electric
cable and steel wire rope. In addition to
high-speed tubular stranding machines,
cage-type stranding machines and central
stranders, and drum twisters for the cable
industry are also included.
In German, drum twisters are referred to
as universal stranding machines, and this
is a better description of the role for these
machines – all-purpose machines which
can be used universally. Drum twisters
are usually to be found wherever cable is
produced.
More specifically, the main areas of
application for these machines are to be
found in:
•
the
manufacture/production
of
energy cables out of round or sector
shaped conductors (aluminium or
copper)
•
the
manufacture/production
of
telephone cables, control cables and
special cable
•
the screening of medium and high
voltage cables
•
the armouring of energy cables with
round or flat steel wires
•
the production of Milliken conductors
for high voltage and super high
voltage cables
•
the manufacture of offshore energy
cables
Sket has been manufacturing and
supplying drum twisters – a relatively
recent machine addition – for over 50
years. The machines are tailored to the
product-specific requirements of the
user.
Right from the planning stage the
requirement priorities of the customer
are taken on board and solutions are
proposed which, after acceptance by the
user, are developed through to fruition.
The equipment is in consequence tailored
to the specific needs of the end product,
resulting in a machine design which meets
with all technical and technological require-
ments.
As with other systems, this machine
system also follows the trend towards the
development of ever-bigger diameters
and cable lengths.
Pay-off and take-up bobbin diameters are
typically in the range 1,000 to 5,000mm.
The throughput weights can be more
than 50 tonnes.
In this way the tendency in the cable
industry for ever-longer production lengths
is taken into account and the suitability of
the drum twister for the manufacture of
offshore energy cables is facilitated.

Embracing a wide range of machines
E-FLEX is BLM’s completely electric single-head wire-bending
machine.
The scope of wire is expanding globally. The BLM wire line
includes both single-head and double-head solutions to meet all
production needs.
E-FLEX is designed to process diameters up to 8mm. It has two
bending turrets with clockwise/anticlockwise rotation and is
suitable for 3D bending.
It also enables several bending technologies to be used
simultaneously (flexure, blows, variable radius).
Supplying the wire from a coil ensures automatic operation.
The workpiece is straightened in a single forward movement, at
constant speed, without intermediate stops, ensuring precise
straightening and bending repeatability.
The 3D visual graphic programming (VGP3D) and the continuous
visual support of the processing zone make the machine
extremely easy, comfortable and safe to use.
The machine can correct the program automatically and safely
by searching its database for previous bending experiences that
ensure that the first product to be processed is correct.
