roll outside diameterφ250 ・roll length under 6000mm elastic code type expander roll.
This is an elastic band type wrinkle removing roll. It can be used to remove wrinkles from cloth, non-woven fabric, plastic film, paper and glass fiber.
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 high-grade wrinkle removing roll uses highly refined parts such as sliding resin pieces with extremely low friction coefficient that are attached.
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
This is a wrinkle removing roll with a line speed of 600m/min or less and tension of 980N or less.
Rolls are manufactured with an outer diameter of φ250 (elastic band arrangement: 20 equally divided circumference) and a roll surface length in the range of 2000mm to 6000mm.
- The deployment amount can be adjusted
Adjustable to the optimal deployment amount by changing the tilt of the rings on both sides of the roll with the adjusting bolt. The adjustment status can be checked on the angle scale plate.
Standard deployment amount: 13.1 mm (3° ring tilt angle)
- 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.
