    Abstract: A bag forming apparatus for forming a flat bottom of a bag includes a base, opposing sidewalls that extend upright relative to the base, and a top that is operably coupled to an upper portion of each of the sidewalls. The top has an intermediate pivot axis between the sidewalls that enables the top to pivot about the pivot axis between a collapsed state and an expanded state. In the collapsed state, the upper portions of the respective sidewalls are closer together and the top extends upright relative to the base to form a tip for insertion into an opening of the bag. In the expanded state, the upper portions of the respective sidewalls are spaced further apart and the top extends horizontally relative to the base to form a platform for forming the flat bottom of the bag.

    Abstract: A method for manufacturing a sheet material container where the sheet material container includes one or a plurality of sheet members including a main-body forming sheet member that has an outer film layer and an inner film layer which are mutually stacked, a containing region that accommodates contents, and a container body that is configured from the main-body forming sheet member and that surrounds the containing region, and the main-body forming sheet member having a main-body sealing portion, which is an attached region between the outer film layer and the inner film layer, and a non-attached region where the outer film layer and the inner film layer are partially not attached, and further having a filling portion where a filler is enclosed between the layers of the outer film layer and the inner film layer in the non-attached region.

    Abstract: A bag making apparatus includes an intermittent feed device for feeding sheet panels, an adjustment device for detecting upper and lower thresholds for a length of the sheet panels included in a section from a first drive roller pair to a second drive roller pair, a movement device for moving a processing device and a sensor together as a movable group in the longitudinal direction of the sheet panels. The movement device moves the movable group upstream in response to the adjustment device detecting the upper threshold and moves the movable group downstream in response to the adjustment device detecting the lower threshold. If the movable group is moved, the intermittent feed device determines an intermittent feed distance based on a moving distance of the movable group in addition to output from the sensor and feeds the sheet panels by the determined distance using the first drive roller pair.
