Abstract
The envelope is always moved in a direction perpendicular to the fold of the flap thereof. In the course of the moving path the moving direction of the envelope is turned over by means of reverse roller 15, the flap is folded and the opening of the envelope is expanded while the envelope is being halted at the content-inserting portion. In this state the content such as a letter etc. is inserted from the expanded opening of the envelope. Then after the gummed flap is damped, the flap is folded and sealed. Thus, the movement of the envelope can be simplified and the enclosing and sealing apparatus can be reduced in size.
