A gluing unit for one terminal edge of a log and a method applicable inside a machine for the realisation of a log, in which the logs ( 14 ) coming from a rewinding machine are fed towards a gluing unit ( 11 ) comprising in sequence a lower unwinding roller ( 16 ), and a upper feeder belt ( 17, 26 ), and immediately downstream of the unwinding roller ( 16 ) at least one section of a sloping plane surface ( 21, 23 ) of a pre-established length, followed by a vacuum suction roller ( 24 ) above which is positioned an upper roller ( 25 ), and then a glue distributor ( 27 ), an element ( 19 ) being envisaged above the unwinding roller ( 16 ) which blows on a terminal edge ( 29 ) of the log ( 14 ) and underneath a photocell ( 20 ) to detect the final edge ( 21 ), an evacuation surface ( 34 ) for the glued log being envisaged, wherein the log fed by the unwinding roller ( 16 ) is placed with the position of the free end out of alignment by an angle (alpha) according to the log diameter and the pre-established length of the sloped surface section ( 21, 23 ) so that the log in this position, rolls down the sloped surface ( 21, 23 ) to position itself on the suction roller ( 24 ) with its free end of the final edge ( 29 ) placed exactly in correspondence with the contact zone with the suction roller ( 24 ).
