Air Expanding Shaft, Key Type Air Shaft with Flange, for Printing Machine Rewinding

Outline:

The air (expanding) shaft is also known as air pressure reel. It is based on the principle of air compression: changes the outer diameter of the shaft, keep it closely combined with the coil tube, so as to facilitate the sending and coiling of the whole material coil. Promote the reasonable, simple, accurate and automatic operation of the production line.

Principle:

The parts (keys) in the shaft body are expanded and pressed out when inflation, which changes the outer diameter of the shaft body, so that the coil tube is fixed on the shaft body with full width and accuracy. And the expanded and extruded parts retract when the internal air is released, and the shaft can be easily taken out.

Usage:

It is widely used in printing, cutting, slitting, coating, compounding and other machineries' releasing and winding scroll.

Functions:

Expands instantaneously for fast roll mounting.

Grips cores securely without core or roll damage.

Used for unwind or rewind positions.

Manual or automatic rotary union air supply.

Positive collapse for quick roll removal.

Reliable performance.

Manufactured to your specifications to suit your equipment.

Ideal for plastic, aluminum or steel cores.

Urethane surface lugs are available to enhance gripping.
