Sket

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.
