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

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

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

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
