  • Patent number: 8425388
    Abstract: The present invention encompasses principally a method of permitting packaging of one or more piece goods in one or more bag units, where said bag units are, in a selected transport direction, oriented after one another and mutually united with the aid of two, each arranged bag side allocated, thickened portions. A first means (1) is disposed whereby each one of said bag units, from a folded and/or united state, becomes openable by causing said respective bag side allocated thickened portions to pass along a distance from one another oriented rails or similar arrangements. A second means (2) is disclosed in order to, in thus opened bag units, allow insertion of one or more piece goods (G). A third means (3) is utilized, whereby each one of said bag units is sealed along a sealing zone, in order thereby to allow the enclosure of said one or more piece goods. A fourth means (4) is adapted to clip and/or cut off a sealed bag through or above said sealing zone, however under said thickened portion.

  • Patent number: 5004395
    Abstract: An arrangment for the discharge of goods (50) from a package band (24) of flexible plastic material comprises a discharge board (60). The package band is provided with pockets (16) placed following one another and is moved along the discharge board so as to place the pockets in positions where a discharging device (71) moves a pusher roll (74) towards a receiving table (82). The pusher roll rests against the outer wall (11b) of the package band and pushes the goods (50) out of pockets (16) of the package band. A retaining device (64) is situated inside a tunnel (18) of the package band and holds the same in place while the pusher roll discharges the goods to the receiving table (82).

  • Patent number: 4943168
    Abstract: A package band (10) is formed of two walls (11a, 11b) substantially adjoining one another and made of a flexible material, e.g. plastic material. Each one of the walls extends from a first edge area (12a, 12b) the longitudinal direction of the package band to a bottom edge (23) common to the walls situated in a second edge area (14) of the package band. By forming joints (15) located transversely to the longitudinal direction of the package band storage pockets (16) are formed one behind another. Each one of the walls is provided in its first edge area (12a, 12b) with a first connecting tunnel (17a, 17b) adapted to co-operate with a filling or emptying equipment. In its second edge area (14) the package band is provided with a second connecting tunnel (18) adapted to cooperate with a mechanical element of the filling or emptying equipment.
