Abstract:
[PROBLEM] A manufacturing method for a bag in which two closing cords are provided at the opening part thereof, wherein, by means of a mechanical method, part of each of a first handle part and a second handle part exceed the width of the bag and protrude from front and rear tubular parts for the insertion of a cord. [SOLUTION] With one end of a thermoplastic resin sheet serving as a free end and the other end serving as a closed end, after a step in which notch parts are punched out, a tubular part for the insertion of a cord is formed, through which a first cord and a second cord, forming a pair of front and rear cords, are inserted. The first cord, which is exposed at the notch part between two adjacent bags, is fused at a prescribed location between an open end part of the tubular part for the insertion of a cord of the subsequent bag and an extension line of a virtual bag side-edge line S, and in the same manner the second cord is fused at a prescribed location between the open end part of the tubular part for the insertion of a cord of the preceding bag and the extension line of the virtual bag side-edge line, the cords are cut and the sheet is fusion-cut along the virtual bag side-edge line.
