ery speed of 250m/min and the max-
imum delivery speed of the drafting
unit is 10 times faster than in ring
spinning.
Among the other machines on dis-
play was Relanit 4.0. The latest ver-
sion is said to achieve 70 rpm for a
30 inch machine during the produc-
tion of plain single jersey fabric with
a speed factor of 2,100, facilitating
production quantities of more than
1,500 kg per day, according to the
company.
The belt drive is controlled over
special servo motors which can be
operated from the machine display.
This is said to guarantee precise
yarn supply, avoiding fuctuations
which can occur due to lint and oil
accumulation when working with
belt drives with quality wheels.
In order to further increase the ma-
chine effciency, the Relanit 4.0 has
a computer-controlled knit-on aid
which increases yarn tension for the
knit-on process automatically for a
short time, improving effciency, ac-
cording to Mayer & Cie.
Mayer & Cie’s S4-3.2 II R striper
was also on display. It is said to be
the frst striper machine in the world
to facilitate production of single jer-
sey striped fabrics with three - or by
combination of individual feeders
also with more colours - at 3.2 knit-
ting feeders per inch.
While most striped fabrics are
generally produced with 1.6 knit-
ting feeders per inch (corresponding
to 48 knitting feeders at 30in diam-
eter), the absolute limit for three col-
ours was a maximum of 2.4 knitting
feeders per inch.
The new model offers 3.2 knitting
feeders per inch (corresponding to
96 knitting feeders at 30 in diam-
eter) and up to four needle tracks
and full plating of elastomeric yarns
on every knitting feeder. This is said
to raise productivity by up to 70 per
cent compared with current pro-
duction levels for 6-colour striping
fabrics, as well as offering the pos-
sibility to use this machine as a ful-
