A label-rejecting station, where labels are carried by a support band along an advancing path. The rejecting station includes a deviator element and a contrast element. The deviator element is arranged along the advancing path and movable between an inactive position and an active position wherein it contacts the support band at a first surface thereof, deviating the advancing path. The contrast element is arranged along the advancing path downstream of the deviator element and includes: an abutting surface provided for receiving partially thereon a second surface of the support band, opposite to the first surface; and a detachment edge provided for detaching a label from the support band when the deviator element moves into its active position.
