roll outside diameterφ50 ・roll length under 700mm elastic code type expander roll.
This is an elastic band type wrinkle removing roll. It can be used to remove wrinkles from plastic film.
Each time the roll rotates, numerous elastic bands repeatedly expand and contract. When a web is wound, it will spread open with the rubber’s stretching action. This will remove wrinkles from the web.
This is an elastic band type non-curved straight wrinkle removing roll. It can be used to remove wrinkles without straining the webs.
- Scope of application

- Mounting direction
The sheet pass line is compatible with any direction from horizontal to vertical.
The sheet winding angle around the roll is generally set in the range of 30° to 90°.
- Further improvement of service life
It is designed to minimize the frictional wear of the rotating/sliding parts to improve the service life of the roll.
