производить материал в форме плёнки(листа или пласта; Сalendering is used to produce a variety of sheet-like polymer products. In particular it is the leading method for processing vinyl. Calenders work by forcing a heat-softened material between two to five counter-rotating rollers that compact the sheet as it passes through. The thickness of the product film is determined by the gap between the two cylinders, called the nip region. The product sheet is then passed over cooling rollers and then may be spooled as a finished product. umich.eduСпиридонов Н.В.)
