  • Patent number: 6341800
    Abstract: A gas bag folding system is disclosed for a gas bag used in an air bag module, as well as a process and device for holding a gas bag in this manner. A top and bottom layer of the gas bag have each at least one main fold, the main folds extending separately from each other. To fold the bag in this manner, the empty gas bag is outspread so that it has a top layer and a bottom layer, the two layers are separately folded and the folds are gathered together to the required size for packaging in an air bag module. A device for folding the bag in this manner includes separate folding devices which extend at least approximately perpendicular to the top and bottom layers of an outspread gas bag that are associated to the top and bottom layers of the gas bag and can be moved in the direction of the outspread gas bag, and in that an overpressure generator that can be connected to the gas bag.

  • Patent number: 6059708
    Abstract: An innovative method of making pinatas utilizes pre-cut and scored cardstock designed with tab and slot closures. Once the shapes are folded and secured, the pinatas can be decorated using traditional or innovative methods. By designing the tab/slot closure of the body on the bottom of the pinata, the enclosed treats may be released in a non-destructive manner.

  • Patent number: 5421804
    Abstract: A collapsible bulk bag which when filled with material has a generally cubical configuration with a pair of end walls and rectangular sidewalls extending between them with all of the walls being of a flexible material. Bowing and bulging of the sidewalls from a planar configuration is retarded and restrained by loops of cord operably connected with the sidewalls. Preferably the loops of cord having portions inside the bag extending obliquely between adjacent sidewalls when the bag is filled. Method and apparatus for making the bag with the double knotted loops of cord are also disclosed.

  • Patent number: 4600091
    Abstract: A carryall handbag and mat formed of a single blank of foldable sheet material, one end being reversely folded onto an intermediate portion of the blank to define a reversely folded portion and an extended portion. A plurality of seams secures the reversely folded portion to define a pocket. In one form of the invention, an endless handle is connected to one edge of the folded blank, over which the blank, when folded, can be draped to define a handbag, and which blank can be readily unfolded to define a mat. In another form, the blank is folded so that the defined pocket can be turned inside out with the extended portion being disposed folded within the pocket.

  • Patent number: 4484350
    Abstract: A glueless paper bag is formed from a single sheet of paper or similar flexible sheet material which is first folded longitudinally upon itself and then transversely to provide an open mouth bag having a closed bottom, pleated, relatively expansible sides, a single ply front wall, a multiple ply rear wall and a locking section which is tucked into the open mouth of the bag in overlying relation to the multiple ply rear wall thereof. The bag may be readily unfolded to provide a rectangular doily or napkin-forming sheet.

  • Patent number: 4475895
    Abstract: This relates to apparatus for effecting the closing of one end of a shirred casing strand. A strand is to be automatically presented to a previously developed closer in alignment therewith and under a preselected pressure. A transfer device is provided for receiving a doffed strand, transferring the strand transversely and then moving the strand longitudinally so that an end of the strand engages the closer. A gripping mechanism is provided which includes a pair of jaws having opposing clamp elements of a generally V-shape or angle cross section. The two jaws are simultaneously movable either together or apart and are urged apart by compression springs. A fluid cylinder actuated linkage urges the jaws towards closed positions. By varying the closing force, the clamp members can be first moved to a preset spacing providing a receptacle into which a doffed strand of a predetermined size may be readily slid.
