Krishna Engineering Works India, offers a comprehensive range of Expandable Shaft for different industries. we have been manufacturing Expandable Shaft, Air Pneumatic Shaft from last 25 years with premium quality to meet international standard.

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.
The shaft can run at very high speed.

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.

Sizes:
Suitable for Core ID. 3″ and 6″
Length as per requirement

QUICK LOCK SHAFT:
The Economic model for Re-winder shaft having all the advantages like slippage, accommodating gauge variation, smaller core width etc. With the only limitation of time needed for repositioning of the core. This shaft is suitable for Paper Cores. Doctoring Rewinding Machine

Sizes:
Suitable for core I.D. 3″, 4″ & 6″
Length as per requirement
Individual Quick Locks are also available having a width of 50 mm, 75 mm, 100 mm and 300 mm. The bore of Quick Lock is tailor made.

MULTI-TUBE SHAFT:
In case of failure of the bladder, though having least chance, the shaft can hold the core till the process complete.
The damaged bladder can be changed easily, even on the machine.
Expanded area is available almost all over the length of the pipe body. A Very small width of the cores is possible to hold.

Specifications:

Low down time high productivity
Thickness tolerances made, extra precision parallelism and flatness
Suitable for slitting non-ferrous metal like aluminum & brass as well as stainless steel
Optimum hardness for wear resistance.

Krishna Engineering Works India, Load Cells manufacturer, exporter and supplier with international quality standard. We have been manufacturing load cells from last 25 years India. Premium quality of Load Cells to meet client’s requirement for different machinery all over the world. For ratings beyond 150 Kg, Up to 1000 Kg, these are manufactured in compression& tension-type constructions, cater to most of the popular sizes load cells & applications. All Load Cells are excellent in linearity and repeatability with a nominal output of 1mV/V or 2V/V depending on applications. Load Cells meet international standards and high quality for longer durability.

 LOAD CELLS:
1) Edge Guiding

The most popular type of web position control includes achieving the desired edge alignment of the film at various stages of the process. Such a system is especially useful for flexo printing, gravure printing, extruders blown film plant, extrusion laminate, slitting machine etc.

2) Chaser Guiding

One another type of web position control includes chasing one or two webs to a reference web to achieve the desired edge alignment of multiple layers. This is done by either mechanically or electronically slaving two or more sensors. Such a setup is useful for Lamination Machine process.

3) Center Guiding

Center guiding application may involve either fixed or moving sensor system. The Web Guide System keeps the center line of the web in an exact position. In case of Moving sensor center guiding the sensors continuously reposition themselves automatically to detect both web edges and maintain the center line of the web in an exact position irrespective of any width variation.

4) Line Guiding

This system uses a printed line or continuous patch or any pattern on the web. The system maintains the chosen mark (printed line or pattern) in exact lateral position irrespective of the web edge position. This system is widely used in slitting machine.

Instruction:

• Normally, Pneumo – Hydraulic Web Guiding System is used for any winding & unwinding application for guiding the web to reduce the wastages of the material & to get high production output with minimum manpower.
• Now, seeing the emerging demand of the market & few limitations of Pneumo-Hydro Web Guiding System, we have introduced Microprocessor based fully Electronic Line/Edge Guiding System with Photo-Cell Feed Back.
• This has specially application on Slitter Rewinder Machine to slit any material like Laminates, Plain or Printed Polyester or other material. Photo-Cell will sense the color, Line or Edge Guide according to your requirement & you will get the uniform slitting.
• PMDC Motor is used for forward-reverse movement of the trolley and it is coupled with Ball Screw arrangement for better accuracy. Trolly (Guiding Assembly) is provided on unwinder of slitting machine & it is guided by Linear Bearing Arrangement.
• On our Controller Two Digital Settings are provided for light & dark color settings. Auto / Manual mode is also provided along with left & right movement of the material. Servo Center is provided through Limit Switch.
• Photo-Cell will sense the line or edge of the material & accordingly, it will give reference to the motor for forward or reverse movement.

ELECTRONIC CONTROL FEATURES:

• Position Control System.
• Adjustable track control with deviation display.
• The LED emission sensing offering the possibility of operating on all contrast & backgrounds, presenting different surface treatments.
• Ultra sonic edge sensing or op to electronic sensing.
• High response motor powered actuator.
• Proximity switch provided for automatic end travel limits.
