Weighting arms for worsted ring frames
eraSpin weighting arms are characterised by their robust
Tdesign and corrosion resistant nish. These weighting arms
are built to last the lifetime of the ring frame. The loading
springs used on TeraSpin weighting arms are pre-calibrated for
specied loads and also last a lifetime. Each weighting arm exerts
the same load on the top rollers irrespective of how long it is in use
or at what position in the machine it is fastened.
Application/s
Machine : Worsted ring frames with 3-roller-
double apron drafting system
Process : Spinning
Raw material/s: Wool and its blends with man-made
bres and dry-spun bast bres
Features
§ Reliable loading through leveraged force of helical
coil springs
§ Choice of load selection on each top roller
§ Partial load release
Benets
§ Consistent quality of yarn
§ No height gauge setting required after cot bufng
within the specied range of the cot diameters
§ Free from vagaries of pneumatic pressure loss or
pressure variations
§ Suitable for a wide variety of bres and yarn counts
§ Virtually maintenance-free
§ Long service life
Models:
PK 1601-01 YB : Yellow passivation with black knob
PK 1601-01 SB : Silver passivation with black knob

Worsted ring frame top rollers
LP 314-000075 LP 314-000825
LP 316-000075 LP 316-000825
op rollers consist of a pair of anti-friction, double row
Tball bearings with a common axle. Each top roller is
manufactured such that the clearance between the
hardened arbour and shell is perfectly matched with
appropriately sized double row steel balls. The top rollers
made for ring frames and speed frames are injected with just
the right amount of a special grease – TRG 5. The ends are
tted with a uniquely designed seal to prevent leaks while in
operation.

Spindles for worsted drafting
T
eraSpin is one of the few spindle manufacturers who make
complete spindles including inserts that enable ring frames to
attain speeds up to 25,000 rpm (mechanical).
Spindles are available with many different design combinations:
§ Aluminium plug type
§ For manual dofng ring frames
§ For auto-dofng ring frames
p – with knurling and cutters
p – with seal-band and cutters
§ Suitable for
p – 4-spindle tape drives
p – tangential belt drives
§ Equipped with
p – self-locking inserts or external locking hooks
p – spring type buttons or centrifugal type buttons
TeraSpin high performance HF series spindle inserts are well proven
in design and widely accepted by spinning mills and spindle
manufacturers.
Features
§ Reduced blade length to 100 mm (HF 100)
§ Only two point contact (at footstep and neck
bearing)
§ Spring support for axial load
§ Well proven conical foot step design
§ Flexible centering sleeve
Benets
§ Self centering ensures concentric running
§ Low coefcient of friction
§ Very steady even at high spindle speeds
§ Spindle oil requirement reduced by up to 20%
(HF 100)
Distance clips (spacers) for worsted drafting
7
he opening between the lower edge of the cradle and
Tthe nose bar in the drafting zone of a ring frame needs
to be maintained at an optimum level to get the best
quality yarn. If the opening is too wide, it results in poor yarn
quality, whereas if the opening is too narrow, it leads to
undrafted sliver/roving which then causes more end breaks.
TeraSpin distance clips (spacers) are designed to maintain a
precise opening between the lower edge of the cradle and the
nose bar, thus ensuring the best quality yarn. TeraSpin
provides various types of distance clips and each type of
distance clip is customised to ensure a precise opening when
xed on the different cradles as shown in the table.
Application/s
Machine : Worsted ring frame
Process : Spinning

Each top roller is manufactured such that the clearance between the hardened arbour and shell is perfectly matched with appropriately sized double row steel balls. The top rollers made for ring frames and speed frames are injected with just the right amount of a special grease – TRG 5. The ends are tted with a uniquely designed seal to prevent leaks while in operation.

Spindles are available with many different design combinations: § Aluminium plug type § For manual dofng ring frames § For auto-dofng ring frames p – with knurling and cutters p – with seal-band and cutters § Suitable for p – 4-spindle tape drives p – tangential belt drives § Equipped with p – self-locking inserts or external locking hooks p – spring type buttons or centrifugal type buttons TeraSpin high performance HF series spindle inserts are well proven in design and widely accepted by spinning mills and spindle manufacturers. Features § Reduced blade length to 100 mm (HF 100) § Only two point contact (at footstep and neck bearing) § Spring support for axial load § Well proven conical foot step design § Flexible centering sleeve Benets § Self centering ensures concentric running § Low coefcient of friction § Very steady even at high spindle speeds § Spindle oil requirement reduced by up to 20% (HF 100)
  • 7. Distance clips (spacers) for worsted drafting 7 he opening between the lower edge of the cradle and Tthe nose bar in the drafting zone of a ring frame needs to be maintained at an optimum level to get the best quality yarn. If the opening is too wide, it results in poor yarn quality, whereas if the opening is too narrow, it leads to undrafted sliver/roving which then causes more end breaks. TeraSpin distance clips (spacers) are designed to maintain a precise opening between the lower edge of the cradle and the nose bar, thus ensuring the best quality yarn. TeraSpin provides various types of distance clips and each type of distance clip is customised to ensure a precise opening when xed on the different cradles as shown in the table.
