Non-equant roll calender´s structure design and analysis

On the basis of equant roll calender, we have designed non-equant isometric roll calender which applied in macromolecule material. This kind of calender can be realized by decreasing the diameter of one or two rolls properly. And a pair of non-equant roll calender can be constructed by means of one big roll and one small roll. During the process of design, we have built the corresponding mathematical model. And we have calculated the non-equant roll calender´s key problems in accordance with this mathematical model. By comparing with traditional calender, non-equant roll calender has such advantages as high precision, low pressure load, low power consumption and rapid speed.
