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.

What is claimed is: 1. A labeling machine, comprising: a rotating carousel; an input star conveyor for conveying bottles to said rotating carousel; a plurality of pans supported at a peripheral region of the rotating carousel so that each pan of said plurality of pans is rotatable about an axis thereof and is further adapted to receive and support a bottle that is conveyed by said input star conveyor when, as a consequence of a rotary motion of the carousel, the pan is in a specific position for receiving and supporting the bottle; a toothed belt wound around the carousel for driving cooperation with the pans; and a driving pulley for actuating said toothed belt to rotate the pans about the axis thereof while the pans travel, entrained by the carousel, along a path extending between a pan rotation start position and a pan rotation end position, said pan rotation start position being arranged upstream in the path of the bottles, in a direction of rotation of the carousel, with respect to said specific position in which each said pan, already in rotation, receives and supports a bottle. 2. The labeling machine of claim 1, further comprising a plurality of supports, each of which is fixed at the peripheral region of the rotating carousel so as to support a respective one of said pans and rotate therewith about said pan axis. 3. The labeling machine of claim 2, further comprising a plurality of toothed pulleys, each of which is rigidly connected to a respective pan, said toothed belt drivingly engaging said toothed pulleys between said pan rotation start position and pan rotation end position. 4. The labeling machine of claim 1, further comprising a motor assembly for actuating said driving pulley so as to drive said toothed belt in a rotation direction which is the same as that of the rotating carousel. 5. The labeling machine of claim 4, wherein said motor assembly is provided with a belt tensioner for adjusting tensioning of said toothed belt. 6. The labeling machine of claim 1, further comprising a complementary star conveyor that is arranged so as to overlay said pan rotation start position. 7. A labeling machine, comprising; a rotating carousel: an input star conveyor for conveying bottles to said rotating carousel; a plurality of pans supported at a peripheral region of the rotating carousel so that each pan of said plurality of pans is rotatable about an axis thereof and is further adapted to receive and support a bottle that is conveyed by said input star conveyor when, as a consequence of a rotary motion of the carousel, the pan is in a specific position for receiving and supporting the bottle; a toothed belt wound around the carousel for drivingly engaging the pans between pan rotation start and end positions thereof; and a driving pulley for actuating in rotation said toothed belt to rotate the pans about the axis thereof while the pans travel, entrained by the carousel, along a path that extends between said pan rotation start and end positions, and wherein said pan rotation start position is arranged upstream in the path of the path of the bottles, in a direction of rotation of the carousel, with respect to said specific position in which each pan receives and supports a bottle, so that each one of said pans is actuated in rotation about its axis by said toothed belt before and while receiving the bottle in said specific position. 8. A labeling machine comprising a rotating carousel in combination with a driving, rotatable toothed belt, the machine further comprising: an input star conveyor for conveying bottles to said rotating carousel; a plurality of pans supported at a peripheral region of the rotating carousel so that each pan of said plurality of pans is rotatable about an axis thereof and is further adapted to receive and support a bottle that is conveyed by said input star conveyor when, as a consequence of a rotary motion of the carousel, the pan is in a specific position for receiving and supporting the bottle, said toothed belt being wound around the carousel and drivingly engaging the pans between pan rotation start and end positions thereof; and a driving pulley for actuating in rotation said toothed belt to rotate the pans about the axis thereof while the pans travel, entrained by the carousel, along a path extending between said pan rotation start and end positions, said pan rotation start position being arranged upstream in the path of the path of the bottles, in a direction of rotation of the carousel, with respect to said specific position in which each said pan receives and supports a bottle.
