Abstract

L’invention concerne une extrudeuse (1) comprenant une première vis (2) et une seconde vis (3) coniques, montées contrarotatives dans un fourreau (4) et qui définissent un étage volumétrique (11) au sein duquel les filetages (5, 6) sont interpénétrés et conjugués l’un par rapport à l’autre de sorte à former, entre le fourreau (4) et les vis (2, 3) une succession de chambres (7, 8) fermées en forme de C afin de conférer à l’extrudeuse (1) un fonctionnement volumétrique, et en ce, dans une partie au moins de l’étage volumétrique, le pas (P5, P6) du filetage desdites vis (2, 3) augmente selon une loi de compensation (LP5_11, LP6_11) prédéterminée, de préférence quadratique, afin que les chambres (7, 8) fermées successives présentent chacune un volume individuel qui reste égal à un volume (V2, V3) constant prédéterminé formant la cylindrée de la vis considérée (2, 3).
