Abstract: The invention relates to a kneading machine which comprises a substantially cylindrical bowl for containing a mass to be kneaded and a pair of kneading tools rotatable within the bowl with the same direction of rotation, around two axes parallel to the axis of the bowl, so as to define two theoretical cylinders which are substantially tangent both to each other and to the circumferential wall of bowl. Each kneading tool comprises at least one arm which extends substantially on the periphery of the respective theoretical cylinder, so that each arm has an orbital movement around the respective axis of rotation. Each kneading arm is substantially straight for at least one part of its length and is parallel or slightly incline with respect to a generatrix of the respective theoretical cylinder. Preferably the rotations of the two arms are synchronize with each other so that the two arms pass substantially simultaneously at the area where the two respectively theoretical cylinders are tangent to each other.
