The 4-roll calender offers the advantage of working air out of the rubber more thoroughly and gets uniform thickness of film or sheet. It can also be used to coat the rubber film with single or both sides of textile operation.
In the calendering process, fabric and rubber or plastic material is passed through a series of rollers to flatten, smooth and commingle the two or more materials. The more rollers are, the more rolling, and more effective.
It is kind of precise and durable rolling equipment with simple operation, high precision, and good effect.
