Claim:
A bag manufacturing and packaging apparatus that manufactures a bag by sealing a packaging material formed in a tubular shape and at the same time fills the bag with articles to be packaged, the bag manufacturing and packaging apparatus comprising: a tube dimensioned to feed articles into the bag with the packaging material extending around an outer surface of the tube, the tube having an upper end and a lower end with a downstream direction of the flow of articles to be packaged corresponding to movement from the upper end in the direction of the lower end; a conveyance mechanism configured and arranged to convey the packaging material in a conveying direction that parallels the downstream direction, the conveyance mechanism being operative to move the packaging material along the outer surface of the tube; a squeezing mechanism including a squeezing unit configured and arranged to sandwich the packaging material at a first location below the lower end of the tube and to perform a squeezing motion so as to move the articles to be packaged in the downstream direction, the squeezing mechanism being configured and arranged to move in a direction perpendicular to the downstream direction for the squeezing motion and being separately configured and arranged to move in a direction parallel to the downstream direction along the packaging material; and a conveyance adjusting unit including a clamping mechanism configured and arranged to move in a direction perpendicular to the downstream direction to clamp the packaging material at a second location below the lower end of the tube and above the first location, the conveyance adjusting unit being configured and arranged to move the packaging material upward towards the lower end of the tube during the squeezing motion of the squeezing unit.
