At the quadrennial ITMA 2019 textile machinery exhibition, which was held 
last month in Barcelona, the new Steiger Vega 3.130 compact flat knitting 
machine for technical textiles was unveiled. The highly anticipated launch 
had been announced at a pre-ITMA 2019 press conference held by Swissmem 
in Lucerne in March.

Steiger, which is now part of the Cixing Group – the world’s largest 
manufacturer of flat knitting machines – is celebrating its 70th 
anniversary in 2019 and is still manufacturing at its plant in 
Vionnaz, Switzerland, as well as in China. The anniversary is one of a 
number being marked by Swissmem member companies, who between 
them can draw on a staggering 4011 years of combined textile machinery 
know-how.

Composites Successes.


According to Steiger CEO Pierre-Yves Bonvin, the company has 
recently had a number of successes in the field of knitted preforms 
for composites, and in one project with the Technical University of 
Dresden, it has successfully developed shaped truck component parts 
for Volvo. It is also working with a notable luggage brand on a
range of the first knitted composite suitcases.

Two other impressive projects in Switzerland have seen the development 
of 3D-knitted shells to support a five-ton concrete structure as part 
of the award winning KnitCandela project, and the design of composites 
parts for the cockpit and seat covers of the Solar Stratos, the world’s
first commercial two-seater solar plane.

Modular machine.


The Vega 3.130 is a modular machine dedicated to the production of 
technical textiles and can be equipped with warp and weft insertion 
for inlay applications involving high-performance yarns. It has a 
specific cam-box for semi-rigid yarns, as well as adapted sinker
kinetics.

“The Vega 3.130 is our ‘technical textiles machine’ and is supplied 
in a bespoke manner to clients, depending on the technical 
requirements of their textiles-based solutions,” says 
Sales Manager Carlo Corradi.

“The distance between the needle-beds can be specifically adjusted 
and set and other key features include a special take-down for 
3D products, a new system of clamp and scissors that can cut yarns 
like Kevlar, and a selectable carriage inversion ramp for optimised 
production.”

The machine can also be supplied in a special format to process 
carbon fibre preforms for use in automotive, aerospace and industrial
composite applications. Steiger also launched a new App aimed at 
remote machine control which was demonstrated live. The new App 
would allow for example, a Steiger machine user in say Brazil to 
live link to a Steiger technical expert in Europe for assistance.

The Vega 3.130 on show at ITMA was a 3 system, 10-gauge, 52 inch 
needle bed machine, equipped with direct overhead yarn feed, which 
has a maximum running speed of 1.6m/s.

Stitch Lab.


In addition to its success with these and other projects, Steiger is 
now also reaping the rewards of a business it launched in 2017 called 
Stitch Lab, where experts in knitting and programming work together 
with clients on developing their future applications.

In the Stitch Lab, Steiger technicians and their partners also work 
together on exploring Steiger’s MODEL+ 3D simulation software. 
Thanks to the virtual knitting machine function, the creation of the 
stitches, row by row is simulated and so the programmer can detect 
potential knitting problems early in the creation of the garment. 
They can also navigate into the product to inspect 
the sample. A wizard composed of three simple steps is designed 
to help users to easily program their knitwear.

“The Stitch Lab is a very powerful tool to develop future applications. 
In the Stitch Lab Steiger develops 3D articles for knitwear, for medical 
applications and for composite materials,” commented Pierre-Yves Bonvin. 
“In fact,” Mr Bonvin says: “Our new Steiger Vega 3.130 compact flat
knitting machine for technical textiles is a product of our Stitch Lab.


“We will use all our expertise and innovation capability to create new 
patterns and 3D parts using any kind of yarns. In the Stitch Lab 
we have put together the best experts, the best machines and the 
best framework to boost the innovation.”
