ている。2. Description of the Related Art A method of manufacturing a square bottom paper bag with a closing flap having an adhesive band coated with a release paper is disclosed, for example, in Japanese Patent Publication No. 5-77507 (see FIGS. 1 and 5 of the publication). The square bottom paper bag made by the square bottom bag making machine is sent in the longitudinal direction of the bag body with the open end of the bag at the front, and the front edge of the bag is cut by an ear dropping cutter roll with cutting blades arranged in an eight-shape. With a cutter roll having a straight half-cut blade extending in the width direction of the bag, after cutting the left and right corners of the open end of the bag across the four layers of the fold front wall, the fold back wall, and the bag back wall, A method of forming a closing flap protruding from the front wall on the rear wall of the square bottom bag by cutting off the other three walls, leaving only the rear wall of the bag serving as a closing flap separated by the ear dropping. It has been disclosed.

生産性が阻害されることがしばしばあった。However, the so-called half-cut blade has a certain thickness of each laminated sheet and ensures that only the adhesive label base paper is used, as in the case of punching only the adhesive label base paper laminated on release paper. It is suitable for applications where there is no problem even if a slight scratch is made on the release paper. However, as shown in FIG. 2, four layers are provided at one side end including the body sticking portion, and three layers are provided at the other side end. Since the number of layers to be punched is different from the single layer at the layer and the central part, the resistance of the sheet side at the time of punching is different, causing undesirable cuts in the flap part and leaving uncut parts in the cut part. Is not stable,
Productivity was often impaired.

A first step of feeding one sheet at a time at a constant interval in a direction perpendicular to the direction,
Opening from the side edges near the center in the longitudinal direction of the bag body by a distance corresponding to the size of the expected closing flap from the opening edge across the front wall of the fold, the rear wall of the fold, and the back wall of the bag. A second step of cutting diagonally inward toward the edge, and bending only the bag front wall or the bag rear wall separated by the cutout outward, separating and sending the remaining three layers, The three layers are cut off by a rotary knife parallel to the opening edge at a position near the center in the longitudinal direction of the bag body at a distance corresponding to the size of the expected closing flap from the opening edge. The third step of forming the closing flap by projecting the front wall or the rear wall of the bag from the other wall, and the fourth step of providing an adhesive band coated with release paper on the inner surface of the closing flap are successively performed. It is characterized by performing.

するという作用が達成される。According to the method of the present invention, in the first step, the square bottom bags made by a known square bottom bag making machine are fed in the width direction, that is, in the direction perpendicular to the length direction. The two side edges of the square bottom paper bag are rotated with a rotary knife over four layers of the front wall of the bag, the front wall of the pleat, the rear wall of the pleat, and the rear wall of the bag, at a distance corresponding to the size of the expected closing flap from the opening edge, When the bag body is cut obliquely inward toward the opening edge from the positions of the both side edges near the longitudinal center of the bag body, in the third step, only the bag front wall or the bag rear wall of the cut-off portion is moved upward or downward. It is possible to bend downwards, i.e., outward and separate from the other three layers, so that the remaining three layers are scheduled from the opening edge without unnecessary flaws or cuts at the root of the closing flap. A distance corresponding to the size of the closing flap is located near the center in the length direction of the bag. In this position, the bag can be cut off with a rotary knife in parallel with the opening edge, and the effect of projecting the previously separated bag front wall or bag rear wall from the other side wall to form a closing flap is achieved. You.

う作用が達成される。In the third step, the bag forming the closing flap is bent before or after the bag wall forming the closing flap is separated upward from the other three layers. When a crease is cut from the opening edge of the wall toward the center of the bag by a predetermined size of the closing flap in parallel with the opening edge, the bag wall is separated from the other three layers. It is easy to bend, and the effect that the closing flap of the completed square bottom paper bag is bent to make it easy to close the square bottom paper bag is achieved.

い。One means for carrying out the third step is shown in FIGS.
As shown in FIG. First, the portion serving as the closing flap 18 of the bag rear wall 14 is sucked and bent downward by the vacuum guide plate 43, and is separated from the bag front wall 11, the fold front wall 12, and the fold rear wall 13 to be fed. As a result, the separated portion of the bag rear wall 14 passes beneath the guide plate 44 and is bent substantially vertically downward along the guide plate. On the other hand, the three layers of the bag front wall 11, the pleat front wall 12, and the pleat rear wall 13 pass over the fixed blade 45, and at this time, the blade 41 of the rotary knife 4
Thereby, it is cut along the edge of the fixed blade 45. In this way, the closing flap formed on the bag rear wall 14 is not damaged by the blade 41 of the rotary knife 4 because there is no chance that the bag rear wall 14 comes into contact with the rotary knife 41.

The steps will be described. In the fourth step, a (hot-melt) pressure-sensitive adhesive 55 is applied to the inner surface of the closing flap 18 formed in the third step, and a release paper piece 5b cut to a fixed size is attached. FIG. 9 is a schematic side view of one means for performing the fourth step of the present embodiment, and shows a continuous band 5 of release paper.

て閉鎖用フラップを形成することができる。According to the method of the present invention, in the first step, a square bottom bag made by a known square bottom bag making machine is fed in the width direction, that is, in the direction perpendicular to the length direction. The edges of both sides of the square-bottomed paper bag are rotated by a rotary knife over four layers of the front wall of the bag, the front wall of the fold, the rear wall of the fold, and the rear wall of the bag, for a distance corresponding to the size of the expected closing flap from the opening edge. When the bag is cut obliquely inward from the position near the center in the longitudinal direction toward the opening edge, in the third step, only the bag front wall or the bag rear wall of the cut portion is bent upward or downward. It is possible to send separately from the other three layers, without unnecessary flaws or cuts at the root of the closing flap,
The remaining three layers can be cut off by a rotary knife parallel to the opening edge at a position near the center in the lengthwise direction of the bag from the opening edge at a distance corresponding to the size of the expected closing flap. A separate bag front wall or bag rear wall can project from the other side wall to form a closure flap.

From the opening edge of the bag wall to be formed, when a portion close to the center of the bag body is creased in parallel with the opening edge by a predetermined size of the closing flap, the bag wall is separated from the other three layers. It is easy to bend when separated, and the closing flap of the completed square bottom paper bag can be bent to make it easy to close the square bottom paper bag.

When applied to the inner surface of the closing flap, the adhesive applied on the release paper is transferred onto the closing flap and fixed on the flap, so that the inner surface of the closing flap is coated with an adhesive band coated with release paper. It can be provided at low cost. As described above in detail, according to the present invention, an undesired cut or the like is not formed at the base of the closing flap formed on the front or rear wall of the bag, and the other three layers of the opening end are reliably cut off.
