A tab system for a folder (10a), and a method of making same is disclosed. The tab is enlarged to carry more information/indicia. The visual indicia space (16a), i.e. the viewable space on the front (32a, 36a) of the folder which allows viewing of the enlarged tab is achieve without violating the overall size restrictions (40a) of the file folder. Instead, the front of the folder adjacent to the tab on the back panel, is cut away (32a,34a) to expose a greater portion of the back panel (14a) and allow an increase in visual indicia space. The remaining portion of the front panel, not adjacent to the tab may also be cut away (34a) to allow other enlarged tab files, with offset tabs,(22, 21a) to be viewable behind the present file.

A method and apparatus for making a stepped end on a tube of flexible material includes a tube slitting station having a slitting tool with double edge slitting to provide respective slits beside a first panel and beside a second panel, respectively; a first trimming station trimming a first panel of the tube to a first shortened length, a second trimming station trimming the side gussets to a second length, wherein the second length is longer than the first shortened length; and an adhesive applying station applying adhesive on the tube above and below a fold line across the tube, wherein the tube is adapted to be folded along the fold line, and the adhesive material is adapted to form an adhesive to adhesive seal above and below the fold line.

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.

According to an apparatus for successively making the plastic bags, wherein the wastes 14 are formed in at least two areas adjacent to each other widthwise of the plastic film 1, and the apparatus can determine whether all of wastes 14 of each of the areas are discharged.

The apparatus comprises at least one partition plate 20 in a suction path 16. The suction path 16 is divided into at least two widthwise of the plastic film 1. The wastes 14 is guided to each of the divided paths 21A, 21B, 21C, 21D and is discharged. The wastes 14 is detected by an optical sensor when the wastes 14 is discharged to each of the divided paths.

A flexible side-gusseted package and methods of making the same are disclosed. The package has a central longitudinal axis, a front panel, a back panel, and a pair of gusseted side panels. The front panel is secured to the gusseted side panels along a pair of side seal lines. The back panel is secured to the gusseted side panels along a pair of side seal lines. Each of the seal lines includes a pair of end portions and an intermediate portion. The intermediate portion, e.g., a concave recessed portion, of each side seal line is located closer to the central longitudinal axis than the end portions of the side seal lines to provide a package which is somewhat necked-down at its middle, to facilitate grasping of the package by users.
