1. A machine for fiberizing mineral wool by free centrifugation, the machine extending along a longitudinal direction and comprising:
a drive unit positioned at a first location along the longitudinal direction and including an output rod that extends along the longitudinal direction;
a frame positioned at a second location along the longitudinal direction and on which is mounted at least one centrifugation wheel, said at least one centrifugation wheel being connected to a transmission shaft extending parallel to said longitudinal direction and adapted to rotate the at least one centrifugation wheel by transmitting a movement of rotation of the output rod of the drive unit, and
at least one intermediary transmission box connected at least by one input to the output rod of the drive unit and by at least one output to the transmission shaft, said at least one intermediary transmission box being arranged at an intermediate location along the longitudinal direction that is between the first location and the second location and between the output rod and the transmission shaft such as to transmit the movement of rotation of the output rod of the drive unit to the transmission shaft,
wherein the output rod is connected to the at least one intermediary transmission box using a first belt and at least one first pulley,
wherein the belt is coupled to a separate rod arranged in the at least one intermediary transmission box,
wherein the separate rod is coupled to the transmission shaft via a second belt and a second pulley, and
wherein the second belt and the second pulley are arranged between the at least one intermediary transmission box and the at least one centrifugation wheel.
