Abstract

Calender comprises two nearly touching parallel cylinders driven in opposite directions. The mix is transferred up to one end of the mixer by at least one oblique scraper, the blade of which can rest on the surface of the cylinder which carries the layer of material. Specifically the active blade of the scraper may have a profile corresponding with the intersection of the surfaces of the cylinder and scraper. There may be at least two parallel scrapers spaced between one end of the mixer and the peeler.
