Differential Shaft is
a sophisticated winding shaft for slitter re-winder
machine, used as duplex shaft winder (centre winding
It is capable of compensating speed variation due to gauge variation
with multi cores.
Minimum 20 mm core width is possible.
Reel holding is possible at any position across the width.
No-time lost in re-positioning cores since no distance pieces are
Shaft can run at very high speed.
shaft consists of slotted shaft, rubber bladders, hard and
ground steel cage with ball type gripper.
Suitable for core ID. 3" and 6"
Length as per requirement.
Load up to 2 tons
Suitable for Core l. D. dia 3", 4", 6", 8" (metric size and special
sizes also produced)
Length as required
Speed up to 1000 Mtrs/min
Suitable for core materials: Paper, Steel, Thermoplastics
Minimum core width 20 mm
General Materials of Construction
Pipe - Steel
End Generals - Steel - simple or hardened
Cam - Brass
Lugs - Hardened Steel / Rubber
MECHANICAL SHAFT (BLADDER LESS SHAFT)
This is a lug type
shaft but core holding is initiated mechanically and not
pneumatically. This shaft mainly consists of slotted pipe,
steel lugs, brass cam, ratchet etc. The shaft is capable of
taking any challenge arising out of heavy load and speed.
It is possible only because of positive gripping and core
centering achieved without any extra efforts with the help
of cam/lug design. It is very much advantageous with cores
having uneven inside diameter. Key and alien-cap bolt
prevent any shearing of journals - pipe assembly. we also manufacturer all type of Air Shafts like, , mechanical shaft, quick look shaft, multi tube shaft, leaf type air expandable shaft, lug shaft, ball shaft, mechanical expanding shaft, bottom knife holding shaft, multi bladder shaft, spare parts of air shaft, differential shaft, clutch shaft and many more.
Suitable for Core ID. 3" and 6"
Length as per requirement
QUICK LOCK SHAFT
Economic model for
Re-winder shaft having all the advantages like slippage,
accommodating gauge variation, smaller core width etc. With
only limitation of time needed for repositioning of the
core. This shaft is suitable for Paper Cores.
Suitable for core I.D. 3", 4" & 6"
Length as per requirement
Individual Quick Locks are also available having width of 50 mm, 75 mm,
100 mm and 300 mm. The bore of Quick Lock is tailor made.
This is a very
commonly used shaft. It mainly consists of slotted pipe,
journals to suite users machine, lugs, rubber bladder and
non-return valve. These types of shafts are suitable for
both unwinding and winding stages. It can accommodate
single core, multi cores of the width more than 150 mm.
Type of pipe material, lug material are decided based on
duty conditions like load, speed and core material. The
limitations are, it cannot take care of gauge variation or
individual core speed variation since slippage is not
achieved and core width less than 1 50 mm.
Suitable for Core ID. dia 3", 4", 6", 8" (metric size and special sizes
Lengths as per customers requirement
LEAF TYPE AIR EXPANDABLE SHAFT
This type of shaft
mainly consists of slotted base pipe, metal leaves with
knurling/serration, rubber bladder, non-return valve and
This type of shaft can
be used at unwind station, but mainly used at rewind stage
for advantages like:
Narrow width of core
To prevent damage to thin cores (100 % support available to the core
At times core-less winding is also possible
This also has a
limitation to accommodate gauge and speed variation.
Suitable for core ID. 3, 4 and 6 (metric size and special sizes also
