| 81 | Process of making T-shirt bags | US35469 | 1987-04-07 | US4759742A | 1988-07-26 | Fritz Achelpohl |
| In a process of making T-shirt bags a flat tubular film that is provided on each side with at least one gusset is provided with top end seam welds, which close the gusset portions to form handle loops, and with cutouts, which are similar to the neckline of a T-shirt and extend through the inner creases of the side gussets, and the tubing is then folded on itself about its longitudinal center line and is thereafter formed at its bottom end with seam welds, which join all plies, and is formed between adjacent top end and bottom end seam welds with transverse perforation lines or with hot wire-welded joints to separate adjacent bags from each other. Before the folding of the tubular film on itself about its longitudinal center line those portions of the tubular film which are subsequently provided with the top end seam welds are provided with layers of a release agent which extend across the web and prevent a welding of the web. The tubular film is subsequently folded on itself so that the release agent layers lie on each other. The tubular film which has been folded on itself is subsequently provided with the top end and bottom end seam welds. | ||||||
| 82 | Process apparatus for making differently-shaped polyethylene bags and the method thereof | US850523 | 1986-04-11 | US4698112A | 1987-10-06 | Chang L. Chiang |
| An apparatus for producing various shapes of polyethylene bags includes a heating mold separating means, a cutting mold separating means and a collecting means. By using such an apparatus for making PE bags, a double-layered polyethylene sheet rolled on a roller is transported into the heating mold separating means by input rollers to form polyethylene bags of any desired shape. Since the bags can not be completely separated from the sheets by heating mold, the bags together with the sheets must be sent into the cutting mold separating means by transporting rollers again. The cutting mold separating means will cut the boundary of the bag except the root portion, so that the bag is completely separated from the sheets, except for the root portion. Finally, the bags together with the sheets are sent into the collecting means. The cutter of the collecting means indents the root portion of the bags and the needles of the collecting means pokes through the root portion of the bags. Therefore, the bags are produced and completely separated from the sheets and then collected in the collecting means. Further, the waste sheets are transported by output rollers to a waste sheet collecting roller for reuse. | ||||||
| 83 | Double funnel bag material and method | US749815 | 1985-06-28 | US4651504A | 1987-03-24 | Per Bentsen |
| Double funnel bag material and method, wherein continuous length plastic film material is formed into a plurality of coextensive funnel strips connected together as formed. Each of the funnel strips is provided along an edge which is remote from the edge connection with the companion strip, with a zig-zag edge defining a series of funnel pockets therealong.

| 90 | Folding of flat sheet to exact interior height | US526830 | 1983-08-26 | US4530729A | 1985-07-23 | Gilbert Fuchs; Norman Crowley; Randall Wink |
| A folding apparatus and method for folding a flat sheet so that an exact interior height is provided between the two folded portions is disclosed. The flat sheet is folded about a shim having a folding edge which is rounded and which has a thickness corresponding to the desired interior height. The flat shim is positioned on the flat sheet with the edge of the shim located along the line where the fold in the sheet is to be made. Initially, the portion of the sheet away from the shim is folded approximately 90.degree. by tangential bending on the folding edge of the shim. Next, a die having a facing edge mating with the folding edge of the shim is pushed onto the folding edge of the shim. The portion of the sheet which was folded 90.degree. is thus folded onto the top of the shim to approximately 180.degree.. With this two step folding, an exact interior height adjacent the fold is provided. The method and apparatus of the present invention is conveniently used for forming flat jackets having an exact interior height. A plurality of these flat jackets can be formed by providing a plurality of forming devices on a turntable where each step of the forming process is sequentially performed. | ||||||
| 91 | Container having a selectively openable seal line and peelable barrier means | US619647 | 1984-06-15 | US4519499A | 1985-05-28 | Albert Stone; Edwin Pyde; Peter Carveth |
| A unique container is disclosed which has at least three chambers for the separate storage and selective mixing of at least two components. The container includes two outer flexible sheets and an inner, diaphragm sheet, all sealed about their peripheries in the preferred embodiment. Multiple breakable lines of securement are formed between one of the outer sheets and the inner, diaphragm sheet. Multiple permanent lines of securement are formed between the inner diaphragm sheet and the other outer sheet, extending substantially parallel to and substantially the length of the respective breakable lines of securement. Such a container structure defines two chambers which have no common boundary and an intermediate chamber. In the preferred embodiment of the invention, the intermediate chamber does not store any substance; rather, it serves as a buffer or barrier chamber and also acts as a test for seal integrity. In another embodiment of the invention, the intermediate chamber holds a third component for mixing. | ||||||

| 95 | Method for production of album leaves | US499678 | 1983-06-06 | US4431470A | 1984-02-14 | Bernhard A. Schubert |
| The invention relates to a method and to an apparatus for the production of stamp or photo album leaves with slip-in pockets for the stamps. Two transparent sheets in web form are linearly bonded to one another, and slip-in pockets are stamped out of the bonded sheet material to form double sheet pockets joined along a linear edge. The slip-in pockets are stamped out of the double sheet web by a stamping tool assembly in a predetermined arrangement corresponding to the pocket placement intended for the album leaf, and holds them firmly in this arrangement by a partial vacuum. In the meantime, an adhesive has been applied to the album leaf in the places provided for the slip-in pockets. The album leaf is then brought into contact with the slip-in pockets held fast by partial vacuum on the stamping tool so that the pockets are secured to the album leaf. | ||||||
