There is described a label transfer device (7, 7') for conveying a label (2) along a path (Q). The label transfer device (7, 7') comprises a transfer drum (20) rotatable around a rotation axis (D) to define the path (Q) and delimited by an outer lateral surface (21) having a plurality of suction holes (30a, 30b, 30c) to retain the label (2) on the outer lateral surface (21) itself during transfer along the path (Q); a suction source (23) apt to exert a suction force on the label (2) through at least a fraction of the plurality of suction holes (30a, 30b, 30c); and a stationary distributor plate (24) rotatably supporting the transfer drum (20) and having at least one air port (25) configured to fluidically connect the suction source (23) to the plurality of suction holes (30a, 30b, 30c). The suction source (23) comprises at least one suction generation unit (35, 35') fluidically connected to the air port (25) and integrally mounted to the distributor plate (24) or being at least partially an integral part of the distributor plate (24') itself.
