| Depending
upon the application the specification
of the cone varies. The popular
sizes in the present Textile Industries
are 9 Deg 15', 5 Deg 57', 4 Deg
20', 3 Deg 30', etc.
In all yarn winding application,
tension at the traverse extremes
pulls yarn towards the cone
centre. So we have to provide
suitable surface finish to the
cones like Embossing, Velvet
Finishing, Flocking, etc.
Generally,
Embossing
is used for coarse and lively
yarns. This surface provides
extra resistance to yarn slippage.
However fine embossing surface
is provided for medium count
yarn and for the threads where
take off could be restricted
by the above bold embossing
surface.
This surface holds winding
to full traverse length, yet
permits free delivery to knitting
or sewing machine.
Velvet
Finish surface is ideal
for fine cotton yarns and prevents
damage to delicate filaments
of synthetic fibres. Yarn will
feed off smoothly without sloughing,
hanging or breaking. Velvet
surface can be provided according
to the requirement.
Flocked
Surface is found quite
suitable for winding Rayon,
Nylon and other low twist fine
filament yarns. This is a smooth
cone with flock finish provided
on either entire areas or bonded
at critical areas. The effect
of flock can be controlled according
to the twist, denier and number
of yarn filaments. This surface
also provides barrier to minimize
absorption of coning oil by
the paper.
A. 9
Deg 15' Cones - Regular,
Plain or Plain Point Nose -
This cone is used principally
for hosiery yarns on the universal
cone winders. The specifications,
colour, tip, surface finish
are all provided according to
the standard requirement.
B. 5
Deg 57' Cones - Regular,
Straight or Plain Point Nose
-This cone is mainly used for
winding single and multiple
and cotton thread, synthetic
yarns, twines, etc. In the latest
auto coner like Savio Italy,
these cones are widely used.
These cones will have either
embossed or velvetted or flocked
surface.
C. 4
Deg 20' Cones - Regular,
Nosed or Plain Point -These
cones are used in two-for-one
twisters, yarn doubling machine
and for some special purposes.
D. 3
Deg 30' Cones - Crimped
Nose -These cones are used to
wind rayon, nylon and other
filament yarns for knitting
or creeling. This can be either
velvetted or flocked surface.
Heavy weight cones are used
for constructive yarns and extra
large packages.
E. 3
Deg 51' Cones - Regular,
Plain or Straight Nose -These
cones are used in tyre-cord
tuffed and carpet yarns of a
heavy nature.
