Technical data
Winder motor: 450W DC 200V
Hollow spindle motor: 450W DC 200V
Winding speed: variable from 200 to 720 m/min.
Twisting speed: min 10m\min with twisting ratio = 1, max 250m\min with twisting ratio = 10
Z or S twisting set by means of selector switch (6 fi g.7)
Winding cone stroke 6” (152mm) 5°57’
Mechanical slub catcher with micrometric control (6 fi g.8)
Waxing: counter-rotating motion with square-holed paraffi n wax ring (10 fi g.8).
Yarn tensioner: two per head (2-4 fi g.8) plus one for each of the two rear creel cones
(1-2 fi g.4).
Threading: automatic yarn threading of waxing assembly
Yarn sensor for each of the two rear creel cones.
Operating instructions
Twister operation
Set the selector switch (6 fi g.7) on - S - if the twisting cone turns clockwise, or on - Z - if
it turns anti-clockwise.
The machine must be halted whenever the switch is operated.
Adjust the twisting ratio with the 10-turn potentiometer located on the right above the
master power switch, marked TWIST MASTER (7 fi g.7).
10 ratios are available, and the ratio can be read off the graduated scale located
directly above the potentiometer itself. Each turn of the potentiometer increases the
ratio by 1, passing though the intermediate values.
The highest number of twists (185/m) is obtained with the smallest ratio (0), while the
smallest number of twists (20/m) is obtained with the highest ratio (10).
The potentiometer located to the left of the TWIST MASTER potentiometer sets the
winding speed; adjusting this latter potentiometer does not affect the twisting ratio
(5 fi g.7).
Threading the Hollow spindle
A yarn can be twisted onto 1 or 2 central yarns spooled off two rear cone holders
located directly below the hollow spindle (3-4 fi g.4), passed through the yarn sensors
and yarn brake directly above, run through the yarn guide and into the hollow spindle,
through the two pulleys underneath the machine, passed to the front, and through
the feeder, after which they follow the traditional threading through the waxer as for a
normal winder.
The cone with the yarn to be twisted into the two yarns whose route is described
above is placed on the hollow spindle inside the plastic basket (5 fi g.4); the yarn guide
can be rotated over the hollow spindle to facilitate positioning the cone (6 fi g.4).
The yarn is then bound to the other two yarns and follows the same route as them.
To start the machine, use the mechanical feeler as on traditional winders (9 fi g.8).
When using the machine in twister mode, bear in mind that the feeder roller and hol-
low spindle do not start and stop together, so a small amount of yarn collects close to
the cone inside the hollow spindle.
The amount of yarn which collects here is proportional to the difference in speed be-
tween the hollow spindle and the feeder roller.
