In a machine for making rigid hinge-lid packets, the lid of each packet is folded by a device ( 9 ) equipped with a plurality of pockets ( 2 ) occupied by respective single packets (P), each presenting a set of end folds ( 20 ) that will be bent inwards to form the lid ( 15 ), also, a belt conveyor ( 3 ) by which the pockets ( 2 ) are directed along a predetermined folding path ( 3 b) between an infeed point ( 10 ) and an outfeed point ( 11 ), a pulley ( 4 ) centred on a vertical axis (X) of rotation, and a folder unit ( 12 ) mounted to the rotating pulley ( 4 ), interacting with a top part ( 13 ) of each pocket ( 2 ) in such a manner as to engage and bend the end folds ( 20 ) of the packet (P). The folding path ( 3 b) coincides with a branch of the belt conveyor ( 3 ) looped around the pulley ( 4 ).
