  • Star-wheel 34 outputs articles 2 dried and suitable to labelled at station O, from which they are conveyed inside labelling station 14.
  • inspection device 17 inspects articles 2, as the latter are conveyed by transfer station 16 along curved path T.
  • inspection device 17 ensures that articles 2 which are not suitable to be labelled in labelling station 14, e.g. because respective bodies 3 are damaged or because caps 15 have not been properly positioned or rings 21 have been detached from relative frames 20, are not conveyed by labelling station 14, thus optimizing the efficiency of labelling station 14 and, therefore, of whole unit 1.
  • the inspection of articles 2 does not require a further dedicated linear station distinct from transfer station 14, thus reducing the whole size of unit 1 and simplifying the layout thereof.
  • unit 1 comprises a discharge device 18, which discharge articles 2 which are not suitable to be labelled along path T.
  • Transfer station 16 comprises star-wheels 31, 32, 33, 34, which convey articles 2 gripped on respective necks 4 along respective portions T1, T2, T3, T4 of path T.
  • inspection device 17 inspects articles 2 as the latter are gripped on respective necks 4 and conveyed by star-wheel 33, and discharge device 18 discharge articles 2 as the latter are gripped on respective necks 4 and conveyed by star-wheel 34.
  • unit 1 comprises a plurality of dryers 35, 36, 37, 38, 39, which are arranged along path T, and progressively and repeatedly dry necks 4, caps 15 and bodies 3 of articles 2 travelling on this path T.
  • labelling station 14 is fed with dried articles 2 and can therefore properly operate.
  • nozzles 41a, 41b, 42, 43; 52a, 52b; 53a, 53b; 54a, 54b, 55a, 55b. could be used to eject a water flow onto articles 2 travelling along respective portions T1, T2, T3, T4 of path T.
  • fans 40 would be replaced by corresponding pumps.
  • drying stations 13, inspection devices 17 and ejection station 18 can be varied according to the needs, such as for example increasing production speeds.
