- 13 - Abstract The present invention refers to a method for manufacturing a sack or bag with a bottom being rectangular in the filled state and with a handle piece, and to sacks or bags manufactured according to said method. For the solution of the object to simplify already known methods, at one end of a tube section with side gussets (62), two parallelly pregrooved fold lines (64, 66) extending vertically to the side edges are formed. Then the bottom is pulled open and corner tucks (68) are formed thereby. A rectangular bottom cover sheet (70), onto which a U-shaped folded sheet and reinforcements (74, 76) are bonded by an adhesive, is pasted thereon. After the application of the glue pattern (80), the lower bottom half is folded upwards at the inner fold line onto the upper fold line. Finally, the griphole is punched in below the reinforcement and in the section of the reinforcement.
