ABSTRACT:
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).
