<p>The invention relates to improvements in kneading machines of the type including a fixed support structure (2), a kneading vessel (3) which is circular in plan and is supported for rotation about a central vertical axis (X-X) by the fixed support structure (2), a kneading tool (4) mounted for rotation about a radial horizontal axis within the kneading vessel, and fixed counter members arranged to cooperate with the kneading tool. The main characteristic of the machine according to the invention lies in the fact that the side wall (3a) of the vessel (3), or at least the part (A, B) which cooperates with the kneading tool (4), has, in vertical section, a profile in the form of an arc of a circle with a radius (R) equal to that radius of the vessel which lies in a horizontal plane containing the axis (Y-Y) of the kneading tool, and in that the kneading tool includes at least one arm (6) having a curved end portion (7) located parallel to and adjacent the wall of the vessel.</p> |
