Strander works at speed

The monobitorsion strander, based on a Cortinovis Machinery Patent, is a

high performance strander that combines the advantages of the single and

double twist stranding – the high quality of single twist with the high speed of

the double twist.

Its production range starts from 7 wires up to 61 wires unilay compacted or

compressed strands, with sections from 16 to 300mm

2

. It can handle

aluminium, aluminium alloy and copper wires with continuous pay off from

stem packs with automatic changeover or, if required, pay off from bobbins.

The tension of the wires is equalised in simple and efficient multiple

pneumatic brakes, making it possible to set up wire tension for each layer or

for each wire. A stationary die stand accommodates up to 61 wires, with 2, 3

or 4 lay plates and 1, 2 or 3 rotating driven or idle dies.

There is also the option of a rotating unit with 2, 3 or 4 pairs of compacting

rollers.

The rotating capstan, driven by an AC motor fitted in the rotating frame,

makes and precisely compacts the strand with its final lay and geometric

size. Every capstan turn gives one lay in the strand, as obtained with the

single twist process.

Double twist take up, that receives the strand already made in its final size

and lay, transfers it to the bobbin without giving any stress or variation in lay

and diameter. This is due to a patented system of driven rotating joints, at

inlet and outlet of the bows. On the bow the strand is guided with idle dies

that help to stabilise the strand.

The double twist take up includes the bobbin holding cradle, with feeding

capstan, traversing device, deviation pulleys and pneumatic pintles.

Ultrasonic welding on show

SpliceRite™ Ultrasonic Wire Splicer took centre stage on the Sonobond

Ultrasonics stand at May’s Electrical Wire Processing Technology Expo in

Milwaukee, USA.

SpliceRite is designed to create

perfect solid-state metallurgical

bonds using the lowest possible

voltage drop and minimum energy

consumption. The unit eliminates the

need for clipping, soldering, crimping,

or dipping, quickly splicing wire

bundles without producing arcs,

sparks, or fumes, or melting the wires

and can accommodate tinned or

heavily oxidized wires.

The unit features a microprocessor

controller that can store and recall up

to 250 jobs by height, by energy, or

by time while producing welds.

Ultrasonic welding is environmentally

friendly, produces no waste, and is

economical to use.
