Abstract: A labeling machine that is provided with a rotating carousel supporting at a peripheral region a plurality of pans and with an input star conveyor for conveying bottles to be labeled to the rotating carousel. Each pan is adapted to receive and support a bottle when it is located in a specific position following to the rotation of the carousel. A toothed belt actuated by a driving pulley is wound around the carousel for driving the pans in rotation while they travel, along a path extending along the peripheral region of the carousel, between a rotation start position and a rotation end position. The rotation start position is located upstream, in the direction of rotation of the carousel, with respect to the specific bottle receiving position.
