A screw extruder-calender assemblage consists of a screw extruder and a pair of calender rolls disposed adjacent to the discharge end of the extruder and normal to the lengthwise axis thereof. An equalization chamber between the extruder discharge end and the input side of the calender rolls is formed by the discharge crosswise end of the extruder, peripheral positions of the calender rolls and two side walls; the crosswise width of the chamber adjacent to the calender being equal to the length of the working gap. The quantity of material in this chamber during operation varies with variations in the output of the extruder but always provides a quantity of material sufficient to assure uniform output from the calender rolls.
