June 2009, Frankfurt
- Italian yarn feeder manufacturer LGL Electronics showed its latest
developments at the recent Techtextil exhibition, including its new Spin
tension controlling device and Compact yarn feeder with reduced dimensions and
weight.
Compact
Speaking at Techtextil, LGL’s Enrico Guerinoni told
KnittingIndustry.com, “LGL has designed another new feeder called Compact for
large diameter circular knitting machines, which combines reduced dimensions,
user friendliness and other important recent technical innovations.”
The company says that
Compact is its response to the challenging requirements of today’s world
markets. Compact replaces an electro-mechanical system with an electronic system
to reduce variation and dimensions.
As the name suggests, Compact has very compact dimensions
and reduced weight which is important on machines with high numbers of feeders.
Energy consumption is minimized via a brushless motor and Compact can be fitted
with the same accessories as the company’s Primo, Attivo or Vector feeders.
Compact has a yarn consumption function which offers real time
electronic measuring of the yarn consumption to all feeds (up to 256 max.) at
the same time. Z and/ or S rotation can be selected as needed. Guerinoni
explains that Compact’s on-off switch is easily accessible and the signalling
lamp is visible from anywhere around the knitting machine. It can also be installed
in any desired position, whether vertical, inclined or horizontal.
Compact
characteristics
Yarn counts: from 5 to 600 denier
Speed: up to 700 m/min

Spin
LGL Electronics has also extended its range of feeders
dedicated to all kind of knitting and hosiery machines with a new tension
controlling device called Spin. Spin, which is used with covered and uncovered
elastane yarns has been on test with LGL customers and is now on sale. LGL says
that it answers all of their customers’ needs in the area of yarn measurement.
The precision of a new ceramic tension sensor, electronic
drive and the use of the best materials such as aluminium and the fully
dedicated development of mechanics and electronics give LGL the chance to open
up new horizons in the field of yarn tension control at any speed, the company
says.
According to LGL, Spin reacts quickly to speed changes
without producing tension peaks and has a maximum torque available over a large
speed range (in particular at low speeds). LGL says, it also offers low power
consumption via a brushless motor and is easy to install. Communication is via Serial
and CAN BUS and both flat and single cables can be used. Spin competes with BTSR’s
Ultra and Memminger-Iro’s EFS800.
