Delisi Srl offers automatic wire straightening and cutting machines for smooth and
ribbed wires from 1mm to 20mm diameter.
Delisi machines are versatile and can be customised to suit the customer’s
requirements. Available features include the hydraulic flying shear cut.
Feeding speed is regulated by hand-wheel or electronically. Feeding rolls are never
changed; with the hand-wheel it is easy to select the grooves on the feeding rolls
for the diameter to work. The spinner has a pre-regulated set of straightening
jaws and it takes only one minute to change the wire diameter. The torsion is very
reduced and the wire, after the cut, is cold; the tolerance on the bar length is less
than ± 1m.
An electronic programmer and one or three lines of pneumatically tiltable arms can
be supplied with the rod collection bed; different lengths and different quantities
can be programmed and collected separately in one of the lines of tiltable arms,
without stopping the machine and giving the operator the opportunity to empty
the lower line of tilting arms.

Straightening and cutting
Decalub has developed a rod and wire
dry cleaning system, Smooth-Brush
(SB), which operates in-line with
a wiredrawing machine. The SB
system provides an extra-clean
product by transversal high-speed
ultra-fine brushing all around the wire
circumference with automatically
controlled brush pressure, and ensures
unchanged rod or wire physical
properties with no induced residual
stress.
Rod and wire SB cleaning system
eliminates the most costly parameters
in wire drawing process, including
elimination of acid and wet pre-coating
chemicals, providing downstream
benefits and substantial process
savings.
Suitable for use where the surface
finish is of great importance, the system
offers consistency and can be of benefit
in demanding applications such as
plating wire, CO 2 welding wire and H/C
wires where the ductility is a focus,
particularly in the production of spring
wire, bead wire and PC strand wire.
In rod applications, the system provides
transversal micro-roughing, ideal for
lubricant pick–up during drawing,
enabling even plastic deformation
and a uniform metal flow within
the die at all practical speeds. Brush
bristle penetration is adjustable
to automatically maintain surface
micro-roughness from 10 to 20 microns.
This facility eliminates the need for wet
pre-coating chemicals in the drawing
process, including 0.90%C rod.
In wire cleaning applications, the
system's smooth micro-brushing
capability is used to clean drawn
wire of residual lubricant, enabling
in-line polishing of wire for cold head
applications, metallic and plastic coating
or painting.
