Narrow Web Differential Air Shafts

Product Description
Narrow Web Differential Air Shafts

 Differential Air ShaftDifferential Shaft is a sophisticated winding shaft for slitter re-winder machine, used as duplex shaft winder (centre winding type).

 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 required. Shaft can run at very high speed.

 
This shaft consists of slotted shaft, rubber bladders, hard and ground steel cage with ball type gripper.
Sizes

 Suitable for core ID. 3″ and 6″ Length as per requirement.

Capabilities

 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

Air Shaft ManufacturerHuiyuan SHAFTQUICK 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.
Sizes

 Suitable for core I.D. 3″ & 6″ Length as per requirement Individual Quick Locks are also available having width of 50 mm, 36 mm, 25 mm and 20 mm. The bore of Quick Lock is tailor made.

MULTI-TUBE SHAFT
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 50 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 50 mm.
Sizes

 Suitable for Core ID. dia 3″, 6″, 8″ (metric size and special sizes also produced) 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 suitable journals.
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 ID.) At times core-less winding is also possible

This also has a limitation to accommodate gauge and speed variation.
Sizes

 Suitable for core ID. 3, 4 and 6 (metric size and special sizes also produced) Lengths as required

Lug Shaft:
Grippers are slit through the metal pipe & the pneumatic bladder is used for inflating. The grippers give positive holding of the core.
> These shafts are strong & ridged
> Standardized design allows us to manufacture the shaft in any size diameter
> The same design can be offered for heavy duty to light capability shaft
> Simple design ensuring a long service
> Staggered lug design makes it best in winding application
> Each gripper offers a designed chamfer for easy core insertion
> Dimensional tolerance of journal is very tight for better fitting & rigidity during operation
Material:
> Pipe: Steel or aluminum
> Lug: Steel, Rubber or Plastic
Available Size:
> Core ID from 2″ to 12''
> Length up to 4000mm
Option:
> Cantilever shaft
> Various size of lug (Gripper)
Ball Shaft:
A Shaft specially designed for slitters to handle constant tension on multiple slit. The base steel shaft has multiple bladders, mounted with Ball Locks for reel holding.
> Small width winging possible at very low web tension -A solution for Sensitive Material.
> Each slit material can slip at a different speed and same tension.
> Ball lock with spring design minimizing side movement while setting and running.
> Automatic tension controlling through rotary union in dynamic condition by signals from machine drive.
Available Size:
> 25mm
> 3″, 4″, 5″, 6″ any size possible
> Minimum ball lock width 24 mm onwards

Multi Bladder Shaft:
The Multi Bladder Shaft is made of Aluminum Extrusion with steel journals shrink-fitted for High Torque capability. It is assembled with a PU tube for longevity.
> the Multi bladder is very light and allows easy handling.
> Easy and quick in-house maintenance.
> One can mount core of any width as small as 4mm for slitter rewind.
Material:
> Pipe: Normally Aluminum extrusion. We use steel pipes in case of heavy requirement
> Lugs: Rubber, plastic, and Aluminum
Available Size:
> Core ID: 3″ to 12″ Length up to 3,000 mm (120″)
Option:
> Grapples can be offered as per holding requirements.
> I.E. rubbers, Engineering Plastic, and aluminum.
> We offer one piece steel Body for heavy torque.
