Improved anti-patterning control
package for rotor spinning units
technology
as the special belt and the mechani-
cal anti-patterning gear are also dis-
pensed with in the new system. This
reduces maintenance effort. The
new system completely eliminates
the cost of purchasing or replacing
these mechanical parts.
Perfect package build is the re-
sult of optimal anti-patterning. This
prevents first-order pattern winding
(1:1 pattern winding) and uncon-
trolled package winding. A separate
motor with an electronic random-
check generator ensures optimal
anti-patterning. The rotation speed
of the traversing gear can be finely
controlled. The independent, motor-
powered drive of the traversing gear
also reduces the load on the winding
cylinder drive.
The rotation speed of the winding
cylinder shaft is picked up by a mo-
tion sensor (initiator). The necessary
rotation speed for the motor is calcu-
lated by the controller and transmit-
ted to the inverter. The motor speed
at power take-off is then checked
and regulated. Thus processed, these
Frequency-controlled and motor-
driven, the anti-patterning control
(APC) upgrade package for rotor
spinning machines optimizes pack-
age build. The conversion kit is
available for R 1, R 20 and R 40
(version 1 to 3) rotor spinning ma-
chines.
Higher draw-off speeds in weav-
ing and knitting make optimal pack-
age build increasingly important.
Preventing pattern winding results
in improved take-off behavior in
downstream processing. Electronic
anti-patterning such as that in use
since the R 40 rotor spin-
ning machine (version 4)
has demonstrated its out-
standing qualities in the
field. Customers with R
1, R 20 and R 40 (version
1 to 3) rotor spinning ma-
chines can now also ben-
efit from this innovation.
The APC upgrade pack-
age has been developed
for this purpose. The me-
chanical regulating wheel
has been replaced here by
a frequency-controlled,
motor-powered anti-pat-
terning.
In addition to the me-
chanical
regulating
wheel, the other parts
susceptible to wear such
