Abstract: The invention relates to a method for forming package bodies open at one end from package sleeves open at both ends for the manufacture of filled packages. In order to allow packages with a cross section which is neither square nor rectangular to be formed more simply and reliably, the package sleeves are kept ready for further processing in a stack, folded flat along at least two folded edges running in the longitudinal direction of the package sleeve, the flat-folded package sleeves are transferred in succession from the stack to a forming station, the package sleeves are unfolded in a forming station and the unfolded package sleeves are, in the forming station, pushed onto a mandrel in order to close, in particular seal, a longitudinal end of the package sleeve.

Abstract: A device for opening out blanks supplied in a flattened tubular configuration comprises a store (100) for containing a stack (P) of flattened tubular blanks, a first hooking device (200) for hooking a first flap (1A) of two external flaps (1A, 1B) of a base blank of the stack, and a drum (300) set in constant rotation, peripherally exhibiting angularly-equidistanced work stations (20). Each work station has a retaining apparatus (22) for receiving, from the first hooking device (200), the first external flap (1A), so as to position a score line (2A), connecting the two external flaps (1A, 1B) along an axis C parallel to the rotation axis (11) of the drum. A folding device (29) oscillates in a direction (R) which is opposite the rotation direction (F) of the drum, about the axis (C) so as to intercept the second external flap (1B).

Abstract: An apparatus for inflating film for manufacturing packaging material in situ, wherein the apparatus comprises an inflating unit, a film conveying provision, a sealing unit and a film receiving means for receiving a film roll, wherein the apparatus is a compact apparatus with a relatively small footprint and wherein the inflating unit, film conveying provision and the sealing unit are provided in a central unit on the apparatus and are operatively positioned with respect to a center of the film to be inflated and sealed viewed in a direction at right angles to a film conveying direction, wherein the film to be inflated is operatively engaged only in or near the center thereof by the central unit, for inflating the film from or from near the center, then sealing the film tight and conveying it, as well as a method for manufacturing packaging material.

Abstract: By forming a resin sheet or a metal sheet, an angular-box-shaped bag main body having gore portions on surrounding side faces to ensure its height is formed. A valley line is formed in an intermediate portion of each of the gore portions in a height direction. A triangular overlaid and folded portion is formed in an end of each of the gore portions on each of the surrounding side faces with each corner portion of the angular-box-shaped bag main body being sandwiched between one surrounding side face and another surrounding side face adjacent to the one surrounding side face in which the gore portion is folded in an overlaid manner in the overlaid and folded portion at a same time when another gore portion on another surrounding side face is folded. The angular box-shaped bag main body is folded so as to be in a flat state by allowing each of the gore portions to be folded in a manner to form a valley line along the folded line.

Abstract: A vehicle safety airbag is folded to an annular compact accordion-like configuration for placement around a conventional bag inflator. The bag folding operation involves axially stretching the bag, restraining localized areas of the stretched bag against radial expansion, and axially compressing the bag while moving the restraining devices together, such that annular accordion-like folds are formed in the bag.

Abstract: A method for making block of side-gussetted, bottom-weld bags. Each bag has an opening on one side to fascilitate the removal of individual bags from the block.

Abstract: The invention provides an apparatus and method for automatically opening a plastic bag-type liner as part of a container lining process. The apparatus comprises at least one movable jaw assembly disposed on each side of the liner to be opened and a tongue on the other side of the liner opposing each jaw assembly. To open the bag, the jaws are opened and the jaw assemblies are moved toward and contact the liner and the opposing tongue pushes the liner between the gripping surfaces of the jaws of the opposing jaw assembly as the jaw assemblies begin to move apart, the jaws close, gripping and retaining the layer of liner in direct contact with the gripping surfaces of each jaw, the tongues slide out from between the layers of the liner, separating the sides of the unsealed end of the liner. A stream of air may then be directed into the open end of the bag for completely blowing the bag open prior to placing the bag over the open end of the container to be lined and forcing the liner into the container.

Abstract: An apparatus for separating and erecting foldable boxes has a supply magazine for foldable boxes, a removal device with revolving suction grippers, and an endless conveyor device provided with carriers and blower nozzles, which are disposed laterally of the conveyor apparatus with the blower nozzles arranged to inflate the conveyed foldable boxes. The suction grippers pull the foldable boxes out of the magazine seriatim in the direction in which the foldable boxes extend and transfer them to the conveyor apparatus such that they lie flat on an arc-like stretch. For guiding the chains of the conveyor device and for guiding the foldable boxes in the arc-like stretch, arc-like curved guide rails are disposed on the revolving path of the suction grippers following the magazine. The blower nozzles are associated with a straight stretch of the conveyor device.

Abstract: A cartoner has a side seam gluer for forming flat folded cartons which are vertically oriented in a magazine for feeding into the cartoner. A conveyor having a horizontally-movable discharge chute feeds the flat folded cartons in a vertical orientation onto the feeder. The discharge chute moves horizontally to follow the increasing or decreasing supply of cartons and permits the accumulation of a supply of cartons sufficient to run the cartoner for about two minutes in the event of a jam in the side seam gluer.

Abstract: In a cartoning machine, a conveyor conveys flat folded cartons with their end flaps projecting laterally. A rotating disk having a horizontally-projecting pin engages the flaps in timed relation to their longitudinal movement to press a lower major flap downwardly. When in a downward attitude, the major flap is engaged by a plow or hold-down guide which holds the flap during erection of the carton and loading of the carton.

Abstract: For the fabrication of a bag-in-box (BIB) package, there is first provided a semifinished, collapsed BIB package wherein a flattened bag is placed within a collapsed box and secured to at least one of its inside surfaces by means of an adhesive. After erecting the package, the bag is inflated into close internal contact with the box by introducing a gas under pressure through a fitment attached to the bag and projecting outwardly of the box. The opposite ends of the box are closed with sets of foldable end flaps, with the aid of an adhesive. Preferably, the bag is further secured to the inside surfaces of a pair of opposed ones of the four bottom end flaps of the box. The opposed pair of bottom flaps are held folded out during the introduction of the pressurized gas into the bag, in order that the bottom end portion of the inflated bag may make neat contact with the inside surfaces of the box. There is also disclosed herein an apparatus for thus fabricating the BIB package.
