FIELD: mechanical working of natural fibrous materials. SUBSTANCE: calender mechanism has a number of interacting rolls, each having many teeth arranged round hub surface. Each tooth, at least, in its extreme external part is made in form of plate with side located at angle to hub radius. Rolls are installed on a bearing structure of open framework type on brackets so that trajectory of material movement through them is arranged at an angle to horizontal, preferably, amounting to 45 deg. EFFECT: higher quality. |
