A device for folding vertical flaps of a box-like container (1) moved along a line (100) for packaging products (3) into these box-like containers (1) includes a cam-like member (11), guided along a cyclical trajectory (T) by support and operating means (20) cooperating with trajectory correcting means (6). The trajectory (T) includes a first part (T1), along which the cam-like member (11) moves close to container (1), upstream of said rear vertical flap (5) with respect to the container (1) movement direction (W), and a second part (T2), along which the rear vertical flap (5) is pushed. The second part (T2) is substantially parallel to the direction (W) and concordant therewith. The supporting and operating means (20) include a pulley (21) and a connecting rod (22), aimed at guiding the cam-like member (11) and a bar (13), connected thereto, along a circumference arc. The trajectory correcting means (6) include a rotating body (31), aimed at receiving slidingly the bar (13) in a seat (32) made therein. |
