| 141 | 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. | ||||||
| 142 | 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. The funnel strips have bag wall film attached thereto. Then after separation of the strips and bag wall material assembly along the edge connection, the strips can be rolled-up for future use, or immediately used, by forming into individual bag sections to be filled, and the bag sections separated from the respective strips. | ||||||

| A mixing bag (4) comprising a mixing chamber in the form of a compartment (45), a pocket (42) in the bag having a mouth opening (44) so that it can be filled with liquid (72) to a predetermined volume. The pocket is easily ruptured when the mouth is closed to discharge the volume of liquid into the compartment for mixing with a material (70) in the compartment. During mixing the walls (46, 47) of the pocket about to serve as a nonreturn valve in the bag. | ||||||
| 144 | 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. | ||||||
| 145 | 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. | ||||||
| 146 | Web of bags | US169116 | 1979-10-10 | US4363437A | 1982-12-14 | Wilhelm Scherz |
| There is indicated a web of bags comprising a carrying strip (20), on which individual bags (22) are fastened through discrete suspension sections (24). In the suspension sections (24), there are provided in the end that is to the rear in the direction of delivery during packaging notches (30) which extend to the edge of the suspension sections (24) and which facilitate the blowing-open of the bags (22) in an air curtain that is disposed substantially in the bag plane and is directed towards the filling aperture of the bag. For the very first lifting of the bag front wall, there may be provided in the bag rear wall, at the level of the end of the front wall of the bag, additional holes (18) through which a jet that is vertical on the bag plane can be directed towards the front wall of the bags.To enlarge the transversal zone (W), within which the bags (22) can be separated from the carrying strip (20) by a cut extending in the longitudinal direction of the web, provision is made for the notches (30) to be provided with a substantially transversal section (30a) which extends from the interior end of the notches (30) transversally to the exterior. | ||||||
| 147 | Manufacture of sealed-end tubular thermoplastic net bagging | US945020 | 1978-09-22 | US4190690A | 1980-02-26 | Kenneth H. Rabeneck; Jerry R. Kantlehner; David E. Gallaher |
| A tube of thermoplastic netting is drawn through a work station in a radially collapsed, condensed condition. At the work station, the netting is angularly twisted to rope-like form, to increase its bulk density and, in such condition, is drawn between the die and platen of an ultrasonic welding horn. Periodically, the die and platen momentarily bear against a succeeding short length of the twisted, condensed rope-like form making a fused seal nugget integrating all strands of the netting at that site. The resulting product may be a long length of such tubing, having such a seal every so often, or a plurality of bags formed from the intermediate product by making one transverse cut through the netting tube beside each seal nugget. | ||||||

| The plastic bag may include flexible thermoplastic sidewalls that have a pattern imparted onto them. The wrinkle pattern may be a plurality of linear ribs formed into the sidewall that may be arranged adjacent and parallel to one another. To impart the pattern to the sidewall, a thermoplastic web used to make the sidewall may be directed between a first cylindrical roller and a second cylindrical roller, each of which may have a plurality of spaced ridges extending about their peripheries. When the web is directed between the first and second rollers, the meshing of the ridges may form ribs into the web. | ||||||
