FIELD: automatic packing machines. ^ SUBSTANCE: invention relates to device for folding vertical flaps of box-like containers at closing the containers. Proposed device includes cam element 11 directed along circular trajectory T by means of supporting and driving devices 20 operating together with trajectory correcting device 30. trajectory T includes first part T1 along which cam element 11 moves close to container 1 before said vertical flap 5 relative to direction W of container displacement, and second part T2 along which rear vertical flap 5 is pushed. Second part T2 is practically parallel to direction W conforming with said direction. Supporting and driving devices 20 include drum 21 and connecting rod 22 designed to direct cam element 11 and rod 123 conn3cted with cam element along arc of circumference. Trajectory correcting device 30 includes rotary body 31 designed for accommodating rod 13 in socket 32 made in body, rod being installed for sliding. ^ EFFECT: possibility of folding flaps of containers of different sizes and different flaps without leaving traces of operations of their surface. ^ 5 cl, 13 dwg |
