Abstract (en)
[origin: WO2021205260A1] Invention discloses a method and an apparatus for making easily openable seams at open ends of bags and bags with openable seams. The bags may be block-bottom, pillow-type, and with or without side gussets. For seaming the open end of the bag, the apparatus has been provided with a folding means (19) which comprises a folder (20) which is capable of receiving a flat closing strip (15) and converting it into a U-shaped closing strip (15A) having two arms (15B and 15C), and between which the open end is placed. The apparatus is also capable of receiving a seam opening strip (9) that is placed over the open end that is placed inside the U-shaped closing strip (15A) to form a composite open end (33A). The composite open end (33A) is sewn or stitched to form the easy-to-open seam. The seam is openable simply by pulling the seam opening strip (9).
