ABSTRACT:
A carton flap folding and sealing machine includes a separator, a conveyor, a first folding device, a second folding device, a third folding device and a sealing device. Cartons are orderly position by the separator and sent on the conveyor and moved forward to pass through the first folding device and the second folding device for a front flap and a rear flap folded down, and then through the third folding device for two side flaps folded down. Then cartons are moving into the sealing device to receive sealing operation without interruption, by means of two pairs of glue tapes disposed on a tape support frame and two pairs of upper bases and lower bases working alternately.
