Toyota’s experience in building
weaving machinery with special
servo motor technology is reflected
in the comber. As with weaving
machinery, there are also many
elements here that require a reversal
of rotation several hundred times
per minute. In the past, this was
solved with complex oil bath gears.
This conventional technology has
reached its limit of performance.
Toyota uses individual motors to
synchronously drive the combing
elements on both sides. This mini-
mises the torsion of the elements
and the vibration of the machine.
The significantly reduced combing
condition variance of the 8 comb
heads improves sliver quality. The
performance potential of this ma-
chine by far exceeds the previous
state-of-the-art.
Trützschler’s contribution to the
project is a new head stock with
draw box and can changer. This
includes the experiences gained in
building draw frames with indi-
vidual drives, equipped with highly
dynamic levelling. Disc Moni-
tor, the latest draw frame quality
sensor, has also been integrated.
This permanent quality monitoring
provides the data for automatic self-
optimisation of the machine. Due to
the individual drive technology of
the combing elements, the piec-
ing process, for instance, is auto-
matically optimised. Furthermore,
deviations in lap weight no longer
present a problem, since the sliver
count is permanently monitored and
corrected when necessary.
This leap in technology was only
made possible by simultaneously
integrating the knowhow of Tru-
etzschler and Toyota.
