Straightening, cutting & welding
Straightening and
cutting steel wire
The main features of Delisi’s straightening and cutting machines for steel wire are fast
set-up, easy change of diameter, high-speed production, and flexibility respond to
customer requirements.
Delisi machines can be supplied with a spinner for the rapid change of diameter or with
a roll straightening unit. The machine can be made ready to work a new diameter very
quickly and easily. The operator chooses the necessary groove for the required wire
diameter on the feeding rolls and puts the pre-regulated set of straightening jaws in
the spinner. The maximum feed speed is 200m per minute and the same machine can
be set up both for ribbed or smooth wires.
Customers can select mechanical cut or flying shear cut, and the size of rod collection
bed needed, with an electronic positioner or programmer. The rod collection bed
can be provided with the picker at one or three lines of tiltable arms. This system is
advantageous when the programmed rods finish and tiltable arms rise-up to hold the
new size of wire to be worked. The machine continues working while the operator
empties the container underneath.

Straightening expertise
For more than 35 years, Techna International has handled Witels-Albert products in
the UK. With over three hundred standard straighteners for wire, strip and flat-wire,
numerous straightening rolls and rollers, roller guides (for wire, strip, tube, cable and
rope), a range of pre-forming
heads, driven and manual
cable strippers and transpor-
tation drive-rolls and belts,
the range is available for
material diameters from
less than 0.3mm to 150mm
(model dependent) ranging
from small manually operated
units to semi-automated and
fully automated computerised
equipment.
Although the topic of
straightening has long been
considered as a ”hands on”
operation, Witels-Albert has
elevated the art of straighten-
ing away from the traditional
“trial and error” approach, into a more exact science. By researching and developing
a scientific approach to the subject, and with many years’ continuous involvement in
design evolution, the company is able to provide real expertise, including computer
software, to solve many of today’s complex straightening tasks whilst ensuring consis-
tently reliable straightening, thereby eliminating many of the uncertainties previously
associated with these operations.
This long association results in Techna being able to offer a combination of products,
spares and service, and the technical knowledge, expertise and experience to solve
most guiding, straightening and feeding applications.
Where standard units are unavailable because of unusual or exceptionally complex
operational demands or environments, customised processing equipment can often be
designed and commissioned to customers’ specific requirements.

Butt welding
Ideal-Werk manufactures wire butt-
welding machines for wire drawing mills,
cable factories and wire fabricators.
A wide range of machines, Ideal models
DSH 010 – DSH 180, is offered for welding
steel, copper, aluminium or brass wire.
The welders are said to produce constant
draw resistant welds and have a high
welding capacity as well as superior
reproducibility of welds in all material
grades within a wide welding range from
0.1mm to 18mm wire diameters.
The machine is designed for ease of
operation by unskilled labour with a
common setting of jaw distance.
The machine design is rigid and long
lasting for tough working conditions. Low
maintenance cost is combined with easy
access to all machine components.
Ideal-Werk also offers butt welding
machines for stranded copper and alumi-
nium conductors, Ideal models LSF 001 –
LS 1200, from 0.12mm up to 1,200mm2.
These machines are used by cable
manufacturers in continuous extruding
lines.
All Ideal butt welders are engineered
to weld wire and stranded conductors
as perfectly, as easily and as rapidly
as possible.
