1. A unit for applying glue onto a plurality of labels to be cold-glued on respective containers and for conveying such labels applied with glue, comprising:
a roll covered of said glue and operable to rotate about a first axis; a first carousel operable to rotate in a first direction about a second axis and which comprises, in turn, a plurality of paddles adapted to cooperate with said roll to be applied with said glue and to take a relative label from a storage; a second carousel operable to rotate in a second direction about a third axis and which comprises, in turn, a plurality of hooks adapted to receive respective labels applied with glue from said respective paddles and to move respective labels with glue applied thereon along a path, wherein the first direction is opposite the second direction; a first belt operatively connected to said first carousel and to said roll, wherein said first belt is wound onto a first pulley and a second pulley angularly integral with said roll about said first axis; a second belt operatively connected to said first carousel and said second carousel, wherein said second belt is wound onto a third pulley and a fourth pulley angularly integral with said second carousel about said third axis; a first gear rotatable about said second axis angularly integral with said first carousel and operatively connected to said first and third pulleys; a second gear meshing with said first gear, wherein said second gear is angularly integral with said first pulley; a third gear meshing with said first gear, wherein said third gear is angularly integral respectively with said third pulley; and a stator element fixed with respect to said second axis, said stator element defining:
a first seat is configured to house said first gear; a second seat is configured to interchangeably house one of said second gear and said third gear to position one of said roll and said second carousel on a first side of said first carousel; and a third seat is configured to interchangeably house the other of said second gear and said third gear to position the other of said roll and said second carousel on a second side of said first carousel, wherein said second seat and said third seat extend externally from said first seat.
