A folding and glueing device (30) for folding and applying glue to the closure flaps (5) of blanks in continuously moving "wrap-around" sleeve packaging machines comprises a pair of coaxial and interconnected rotary members (14, 18), at least one driven rotary bar (26) borne in a rotary manner by an

A folding and glueing device (30) for folding and applying glue to the closure flaps (5) of blanks in continuously moving "wrap-around" sleeve packaging machines comprises a pair of coaxial and interconnected rotary members (14, 18), at least one driven rotary bar (26) borne in a rotary manner by and between the pair of rotary members (14, 18), transmission means (15, 28, 27) adapted to rotate the rotary bar (26) in phase relationship with the rotation of the pair of rotary members (14, 18), a closure blade disposed and secured along the rotary bar (26) and spray glueing means (22) positioned between the pair of rotary members (14, 18) in a central zone that does not interfere with the path described by the rotary bar (26) which is caused to move along a circular path by the rotary members (14, 18).

[ I claim:] [1.] A folding and glueing device for folding and applying glue to the closure flaps (5) of blanks (10) in continuously moving wrap-around sleeve packaging machines using cardboard blanks (10) in which the closure flap (5) is articulated on the rear panel (1) of the package (20) to be formed, in which the individual packages (20), partly formed by erecting the rear panel (1) against the rear portion of the product, are caused to advance in succession downstream one after the other along a conveyor line (6a, 6b, 8a, 8b), characterised in that it comprises:a pair of coaxial (z) and interconnected rotary members (14, 18), positioned individually on each side of the conveyor line (6a, 6b, 8a, 8b), adapted to rotate about a first axis (z) oriented perpendicularly and raised with respect to the conveyor line (6a, 6b, 8a, 8b) and actuated in phase relationship with the forward movement of the partial packages (20) disposed along this conveyor line (6a, 6b, 8a, 8b),at least one driven rotary bar (26), borne in a rotary manner by and between the pair of rotary members (14, 18) in the vicinity of their radial periphery, oriented parallel with respect to this first axis of rotation (z) and adapted to move along a circular path, p1 transmission means (15, 28, 27) adapted to rotate the driven rotary bar (26) in phase relationship with the rotation of the pair of rotary members (14, 18),a closure blade (31) disposed and secured along the driven rotary bar (26),spray glueing means (22), positioned in a fixed manner between the pair of rotary members (14, 18) and disposed in a central zone that does not interfere with the above-mentioned circular path described by the driven rotary bar (26).
