Core clamp with leaf-type surface contact. It enables reliable torque transmission without damaging the core, even with thin-walled paper tubes, and is also compatible with direct winding clamps!
The characteristics of the leaf-type shaft are that, unlike a typical shaft where a long, slender rod called a "lug" expands and contracts to grip the core, a semi-circular plate called a "leaf" expands and contracts to hold the core. This results in a larger surface contact area compared to the lug, allowing for the gripping of thin-walled paper tubes without damaging the core. 1. Compatible with thin-walled paper tubes The leaf clamps the core with surface contact, ensuring reliable torque transmission. The leaf does not damage the core even with thin-walled paper tubes due to surface contact. 2. With the direct winding clamp function, the raw material can be clamped with one touch There is also a version with a direct winding clamp function that allows for one-touch clamping of the raw material. 3. You can choose the drive method. It can be manufactured in either air-operated or mechanical types.
