Multi drive unit for propelling a modular conveyor belt, where the conveyor belt is made from a plurality of substantially identical belt links, where each link has a top and bottom surface, two side faces and a front and rear edge, where eye parts projects from said front and rear edges, where the eye parts are separated by openings, such that the eye parts along the front edge of one belt link may intermesh in the openings provided between the eye parts along the rear edge of an adjacent belt link, and that apertures provided in the eye parts perpendicular to the intended travelling direction are superposed and a hinge pin may be inserted in order to hingely connect the overlapping eye parts and thereby adjacent belt links, wherein the unit comprises a plurality of parallely arranged axles, where each axle are provided with a plurality of sprocket wheels, each sprocket wheel having a number of projecting teeth distributed along its circumference, where the sprocket wheels on the same axle are spaced along the axle by means of spacing members, and where at least one axle is coupled to drive means able to rotate said at least one axle, and that a belt is arranged around at least two sprocket wheels on at least two adjacent axles, such that rotation of a first axle by means of the belt causes the adjacent axle to rotate, such that all the plurality of axles are connected two and two by one or more belts, where the propulsion force is transmitted either via the teeth engaging the conveyor belt, or the belts engaging the underside of the conveyor belt.
