Abstract: A method of making a packaging bag from a wrapper sheet includes the following steps: forming a continuous sleeve from the wrapper sheet; forming a longitudinal seal inward of and adjacent to a longitudinal folded edge of the wrapper sheet by bonding overlapping longitudinal edge portions of the sleeve to one another; forming a transverse seal bonding overlapping sheet portions to one another; cutting a tear-open slit through at least three layers of the wrapper sheet in the transverse seal in an area of intersection with the longitudinal seal; transversely severing the sleeve to provide a packaging bag having an open end spaced from the transverse seal; charging the packaging bag with goods through the open end; and forming an additional transverse seal bonding overlapping sheet portions to one another for closing the open end.

Abstract: An apparatus for filling flexible bags includes an endless conveyor having a generally horizontally oriented upper run; and a plurality of bag holders mounted on the conveyor and distributed therealong. Each bag holder includes two cooperating plates extending upwardly from the upper (working) run of the conveyor and movable towards and away from one another.

Abstract: An apparatus for making flat packaging bags from a flexible web of indeterminate length includes a machine frame; a sled mounted on the machine frame for travel parallel to the direction of web advance; a first drive for reciprocating the sled parallel to the direction of advance; a mandrel mounted on the sled; a tubular folding body fixedly mounted on the machine frame and coaxially surrounding the mandrel for bending the web about the mandrel to form a web hose; a first sealing shoe mounted on the sled; a second drive for pressing the first sealing shoe against an outer face of the mandrel for providing a longitudinal sealing seam on the web hose situated between the mandrel and the first sealing shoe; a second sealing shoe mounted on the machine frame for displacements perpendicularly to the direction of web advance; a third drive for actuating the second sealing shoe for providing a transverse sealing seam on the web hose; and a cutter for severing a length of web hose from the web.

Abstract: A packaging bag made of sheet material includes a longitudinal seal situated at the longitudinal bag edge and extending parallel to the bag length. The longitudinal seal bonds together at least two layers of sheet material. The packaging bag further has two transverse seals extending parallel to the bag width and intersecting the longitudinal seal. Each transverse seal bonds together at least two layers of sheet material. A tear-open slit is provided in the longitudinal seal and passes through at least three layers of sheet material of the packaging bag.

Abstract: An apparatus has a first conveyor and a second conveyor to which flat items are transferred, in a substantially lying orientation, from the first conveyor at a location of transfer; an item supporting arrangement forming part of the first conveyor and having a first item supporting surface defining a first plane; and a plurality of separate item carrying elements forming part of the second conveyor and spaced from one another parallel to the conveying direction of the second conveyor for advancing the items thereon. Each item carrying element has a second item supporting surface defining a second plane substantially identical in inclination for all the item carrying elements, and the second planes are at least approximately parallel to the first plane at least in the location of transfer.

Abstract: An apparatus for making sealed packages from two superposed, sealable flexible wrapper sheets, has first and second convex support rings which are radially adjacent for guiding respective first and second wrapper sheets towards one another. First and second sealing discs are supported coaxially with the respective support rings at opposite sides thereof. The sealing discs form sealing disc pairs for longitudinally pressing and sealing together the wrapper sheets along opposite edge zones thereof to form longitudinal seams. There are further provided deflecting rollers situated upstream of the respective support rings for defining loop-around paths for the wrapper sheets on the respective support rings. Each support ring carries a shaping element for shaping the wrapper sheets immediately upstream of the sealing discs. The apparatus also has a sealing station for providing a transverse cutter for severing the sealed sheets into predetermined lengths whereby packages of defined dimensions are obtained.

Abstract: A packing machine for making filled and sealed bags from superposed wrapper sheets, has a pair of cooperating sealing rollers for providing longitudinal seams on the superposed wrapper sheets passed therebetween; a mechanism for rotating unidirectionally the sealing rollers in first and second consecutive steps for providing the longitudinal seams in two consecutive length portions, each corresponding to one-half of the predetermined length; a pair of cooperating sealing shoes movable towards and away from one another for assuming, respectively, a sealing position to provide a transverse seam on the superposed wrapper sheets and an idling position; and a mechanism for moving the sealing shoes, while in the sealing position, codirectionally with the travelling direction of the wrapper sheets during a period in which one of the two steps is performed and for moving the sealing shoes, while in the idling position, against the travelling direction during a period in which the other of the two steps is performed.

Abstract: An apparatus for forming a single-fin wrapper sleeve about articles advanced through the apparatus, comprises a conveyor for advancing the articles in a conveying direction and in a plane of conveyance and a shaping body having a vertical longitudinal halving plane extending parallel to the conveying direction and perpendicularly to the plane of conveyance. The shaping body includes a first main forming surface including a planar surface portion and a second main forming surface joining the first main forming surface downstream as viewed in the conveying direction. The second main forming surface has a gradually closing tubular shape surrounding the conveyor and a longitudinal slot extending underneath the plane of conveyance parallel to the conveying direction and symmetrically with respect to the halving plane.

Abstract: An apparatus for stacking filled flat bags advanced thereto in at least one coherent row forming a bag web of indeterminate length, comprises an advancing arrangement for feeding the bag web vertically downwardly; an orienting arrangement for imparting a back-and-forth oscillating motion on the downwardly advancing bag web; a collecting arrangement situated below the orienting arrangement in the path of the bag web for receiving the bag web in zigzag-folded layers; and a synchronizing arrangement for coordinating the operational speed of the advancing arrangement with that of the orienting arrangement for determining the length of the zigzag-folded layers deposited on the collecting arrangement.

Abstract: A dosage pack includes a first and a second permeable bag joined to one another along a common seam and being arranged in a face-to-face relationship by folding the bags onto one another along a fold line extending in the common seam. A holder string positioned between the two bags has a first end attached to one of the bags and a second end attached to a tag positioned externally of the two bags.
