Hank-to-cone and cone-to-cone winding
a) Fitting the hank
Beat the hank energetically before positioning it on the reel (1 fig.18). In order to
increase or decrease the diameter of the reel, pull the knob (2 fig.18) outward, rotate
it and press it in.
b) Threading (see diagram fig.11, 15, and 19)
The yarn should always come from the upper part of the hank, if the compensating lever
is used (3 fig.18).
Normally the yarn passes from the hank to the yarn guide 4 fig. 15, the upper overfeeder
2 fig. 15, the lower overfeeder 1 fig. 15 and the cone 12 fig. 15.
The yarn tensioners (6-11 fig.9), the slubcatcher (7 fig.9) and the waxer (9 fig.9) are
threaded automatically when the start key of the relevant head is pressed after the yarn
has been passed through the sensor (12 fig.9).
For tangled hanks the compensating lever (3 fig.18) should be used; this will prevent
yarn breakage by using the brake. The first two of the three passages over the
compensating lever 3 fig. 18 must always pass over the upper overfeeder (4 fig. 9)
through the yarn guide (see fig. 19).
c) During the winding operations the compensating lever (3 fig.18) should settle in a
position above the horizontal.
To achieve this, adjust the spring tightener knob (4 fig.7), remembering that for delicate
yarns the knob should be in the raised position, whereas for tougher yarns it should be
lower down. For large hanks and high running speeds it should be lowered.
d) Braking
To obtain more or less soft cones, use the yarn tensioner (11 fig. 9). Remember that
when the yarn tensioner is raised, the braking effect is reduced, and vice-versa. The
yarn tensioner can be cut out altogether by raising and turning the top plate, and can
be easily disassembled for cleaning operations. The same effects can be obtained
using the second yarn tensioner 6 fig.9; increasing the weights provides a firmer cone,
or reducing them gives a softer cone.
The machine kit includes a special larger-size spring to replace the one in the first yarn
brake (11 fig. 9) when especially firm cones are required. It is usually used in cone-to-
cone winding. Remember that the higher the speed, the firmer the cones. Note also that
over-waxing will brake the yarn.
e) Slubcatching
In order to regulate the slubcatcher (7 fig.9), turn the numbered dial (9 fig.9) to find the
best opening for the yarn count.
The machine is prefitted for installation of Uster slubcatchers.
f) Waxing
The amount of waxing can be increased by adding the weights supplied to the waxer
g) Cone-to-cone winding
For cone-to cone winding (see fig. 11) pass the yarn through the ring (3 fig.11) and the
into the cone: the yarn automatically passes underneath the 2 yarn tensioners and
underneath the waxing unit, ready for connection the yarn guide.
The recommended cross-over angle is the second (13°). Slow start-up ensures that the
yarn is not stretched.
