ABSTRACT:
A cap-folding and sealing machine for common or retrieved cartons includes a table, a folding device, a first cap frame, a second cap frame, and a double sealing device. The folding device includes upper swing rod units, a side pressing unit, and a folding guiding arm for swinging and folding a front cap, a rear cap, and two side caps with help of the first cap frame after a carton is moved into the table. Then the carton is moved into the second cap frame and the double sealing device, which seals the upper and the lower side with adhesive tapes by means of two pairs of upper main and lower main sealing members of the double sealing device. The two pairs of the sealing members alternately perform sealing operation so that sealing may be kept on continuously without stopping the machine for replacing adhesive tapes even when used up or ripped off.
