When air is injected, numerous lugs (claws) protrude from inside the shaft, allowing it to clamp the core.
A special roller unit is embedded in the outer circumference of the main body.

Features

• When inserting or removing the raw material, the core slides along the rollers, allowing for smooth and snag-free attachment and detachment.
• This is used to prevent dust generation when inserting or removing the core.
