Expand roller or banana roller whose appearance is similar to banana, is composed of an arc shaft and an abrasion-proof rubber sleeve. It is extensively used in textile machines like calendars, dyeing, bleaching machines and drying ranges and so on. It is used for wrinkle prevention by lengthening and reducing highly tensile fibers such as tire cord sheets.
Expander roller can be coated by Nitrile, EPDM and Teflon, all of which have excellent resistance against oil, abrasion, aging and ozone. Thanks to its outstanding insulating property and resistance to elevated temperature, Teflon is ideal for special coating equipment.
