Insert construction
Spindles with HF inserts
Spindle Blade-Shaft
Compact Neck Roller Bearing
Centering Sleeve
Damping Spring / Oil Spool
Foot Step Bearing
Axial Spring
0 mm
2pointsupport
Well proven conical foot step
Axial buffer spring below the foot step bearing
Precision wound spiral coils of oil spool
Compact neck roller bearing
Steel bolster for better strength and heat
dissipation
In case of HF-100 inserts
Shorter spindle blade length
Reduced spindle oil content (by 20%)
14. 14
Damping effect
Spindles with HF inserts
The spindle is free to spin, but
its lateral movement is damped
Precision wound spiral coils of oil spool,
surround the flexible centering sleeve
and perform a dual task
Dampens vibrations all the way till the
axial spring below the foot step bearing
Facilitates uniform and continuous
lubrication of axial spring and foot step
bearing to neck bearing
15. 15
2-point contact
Spindles with HF inserts
Two point
contact
A point contact between spindle
blade tip and foot step bearing
ensures extremely low co-efficient
of friction and hence, lowest energy
consumption
Freely floating foot-step ensures
continuous alignment of spindle top
part axis with spindle insert axis with
two-point contact
Neck bearing
Foot step
bearing
16. 16
Axial spring below
foot-step bearing
Spindles with HF inserts
Calibrated axial compression spring below the foot
step bearing absorbs load on the spindle tip that may
arise during ring rail motion, doffing and donning
operations
This unique feature of the HF series inserts avoids
accidental damage due to vertical impact
17. 17
Spindles with HF inserts
Watch how oil flows and circulates in the
bolster cavity when a spindle starts
The difference in the cone angle of the foot-step bearing and
the spindle blade tip provides a very good hydro-dynamic
lubrication condition
Thin oil film between spindle blade tip and foot-step bearing
cone keeps the spindle blade tip floating, thus avoiding its
continuous contact with the footstep
Foot step
bearing
Lubrication of
foot-step bearing
18. 18
Spindles with HF inserts
Spindle bolster
Bolster housing made out of steel has following advantages:
No cracking of the bolster housing during the tightening of nut
No blow-holes and hence no oil leakage, which avoids spindle running dry
Excellent heat dissipation ensures retention of oil properties for a longer
period

Top rollers
Features
Each roller assembly is made with the most appropriate
sized balls, matching the ID of shell with OD of axle
Automatic selection of ball size in steps of 0.002mm
Through hardening of axle and outer shells
Effective U-type sealing
Lubricated with special TRG 5 grease
Benefits
Higher load bearing capacity
No ingress of foreign particles
Long re-lubrication intervals
Reduced maintenance
Consistent yarn quality and long life
22. 22
Cradles
Features
Metal and FRP cradles
Rigid and stable structure for use under mill conditions
Design ensures gentle nipping and effective fiber control
FRP cradles are lighter in weights compared to sheet metal
cradles
Clean surface for smooth rotation of top aprons
FRP cradles can easily replace existing metal cradles
Benefits
No deformation with FRP cradles ensuring high quality of
roving/yarn
Common spacers for both FRP and metal cradles
Consistent roving/yarn quality
Maintenance-free
23. 23
Customised drafting up-gradation kits for roving
frames as well as ring frames
Benefits:
Improved and consistent yarn quality
Increased spindle speed and productivity
Reduced energy consumption
Extended machine life
Conversion from cotton to synthetic and vice-versa
An economical option over investment in new
machines
Drafting up-gradation kits
24. 24
Top roller grease : TRG 5
Features
Barium based grease, specially suited for spinning mill
environment (high temperature and humidity)
Good metal affinity
Wider range of working temperature (–30oC to +140oC)
Benefits
Longer lubrication interval
High corrosion resistance
Extended service life
Reduced maintenance cost
26. 26
Smart cradles
Smart cradles for ring frames and roving
frames
Features
Minimum contact area minimises friction
during apron rotation
Unique design ensures a fixed radius and
hence a uniform distance between apron nip
and front roller nip
Accommodates variations in apron length
and maintains uniform apron tension
Benefits
Reduced yarn imperfections
Longer apron working life
Easy apron removal and mounting during
maintenance
27. 27
SYC addresses the drawbacks of a
conventional knurling and cutter
assembly, such as:
Accumulation of residual yarn on spindle
at the end of every doff
Waste of material (yarn)
Involves manual cleaning, entailing many
man-hours
Loss of production
Smart yarn catcher (SYC)
28. 28
Smart yarn catcher (SYC)
Features
Automatic opening and closing of clamping faces with change in spindle
speed
Clamping faces open at about 10500 rpm
Clamping faces close at about 4000 rpm
Firm grip of yarn between upper and lower clamping faces which can align
precisely with each other due to unique mechanism
Flat annular clamping faces enable the clamped yarn to move out of the
device easily by centrifugal forces after every doff
Special cutter for yarn cutting
Benefits
No accumulation of residual yarn
No cleaning of residual yarn – less labour hours
Reduced start-up breaks
Improved ring frame productivity
Very long service life
