  • Patent number: 8225929
    Abstract: A substrate made of a material such as cardboard has characteristics sufficient to visually indicate an occurrence of damage when scraped or punctured to identify damage. The substrate has a flat shape with top and bottom elongated edges and a plurality of breaks along at least the top elongated edge to facilitate bending at a substantially ninety degree angle and be wrapped around a payload carried on a reel at an inner corner where an outside surface of the payload and an inside surface of a flange of the reel meet. The substrate can have a perforated fold parallel to the elongated direction substantially perpendicular to the breaks. The substrate is secured to a reel by stapling, taping or plastic shrink wrapping. A visual warning message can be placed on the substrate to aid forklift drivers.

  • Publication number: 20120058231
    Abstract: A tubular bag packaging for bar-shaped food products is made of a film with first and second longitudinal edges. The film has a first seal section at the first longitudinal edge. A flap section at the second longitudinal edge has a second seal section along the second longitudinal edge. The film is closed at the seal sections by forming a continuous back seam in longitudinal direction as a fold-over seam. The film is sealed at transverse edges by transverse seams. The back seam has end face edges adjoining the transverse seams. The flap section has a linear separation cut as a tearing aid disposed on at least one of the end face edges and extending away from the end face edge in longitudinal direction. The film in the area of the second seal section with linear separating cut has a pressure deformation line that extends in longitudinal direction.

  • Patent number: 7174697
    Abstract: A system and process for packaging groups of products, such as spirally wound paper products are disclosed. During the packaging of groups, a continuous supply of a wrapping material is unwound and cut periodically in the edge regions. Optionally, a perforation line may also be formed into the wrapping material in between the two cut edges. The cut edges form flaps that are then wrapped around the product groups and sealed. The wrapping material is then broken along the perforation lines in order to form individual packages. Finally, the ends of the packages are folded and sealed.

  • Patent number: 6526724
    Abstract: Packaging method and apparatus using multiple packaging material are improved so that multiple packaging filled with goods and sealed may be separated easily to each goods filling section. The multiple packaging material (40, 50) has plural goods filling sections connected in series via adjacent side edge portion (42, 52, 53) between each of the goods filling sections. Goods to be packaged are filled in the multiple packaging material at goods filling portion (12). Multiple packaging so filled with the goods is covered and sealed with sheet coming from master roll (16). The multiple packaging is made separable at the adjacent side edge portion. Overlapped portion of outer peripheral edge portion (41, 51) of the multiple packaging material and the sheet is first sealed at sealing portion (14) and then the adjacent side edge portion is sealed with the sheet at longitudinal sealing portion (21).

  • Patent number: 6112505
    Abstract: Rigid packets of the type with a hinged lid are fashioned from diecut blanks presenting a central longitudinal portion flanked by two lateral portions, each consisting in a series of longitudinally disposed flaps. The method of manufacture involves directing the blanks singly and in succession between a pair of contrarotating rollers with dies shaped and positioned to engage each lateral portion; the dies are designed to modify a pair of adjoining flaps on each side, which ultimately will be bent through a right angle to form an internal layer of the relative flank face of the packet, by producing at least one bend in one flap at an end adjacent to the other flap, and forming a projection on the longer flap which in the finished packet will be breasted permanently in contact with an inner reinforcing frame.

  • Patent number: 6106047
    Abstract: A window molding installed at a clearance between a front window and a window frame of an automotive vehicle has an upper molding and a side molding continuous in the longitudinal direction. The side molding has a strut portion which is formed between a head portion for covering the clearance and a leg portion inserted to the clearance so that a length of the strut portion and an angle between the head portion and a glass limiting lip connected to the leg portion are gradually increased from an end of the side molding connected to the upper molding to the other end. The window molding is produced by extrusion molding by means of an apparatus using a fixed die head and a movable die head.

  • Patent number: 5727367
    Abstract: Packaging material, particularly for forming blanks for hinged lid packets, is delivered to a packaging machine in web form and at least one creasing or shaping operation is performed (44; 112) on the web (2) prior to severing individual blanks (50) from the web. Folding or wrapping of a blank around an article to be packed in the machine is monitored and the creasing or shaping operation varied to optimise machine performance: for example, an adjustable creasing tool can be adjusted to compensate for tool wear. Individual blanks are inspected for longitudinal curl, usually caused by the web having been wound on a reel, and where necessary a correction is applied during feeding of the web, e.g. by adjusting the angle of wrap of the web around a decurling roller (38; 108).

  • Patent number: 4449349
    Abstract: A wrap-around packing machine wherein the packing station and the station which supplied prefabricated blanks are separated from each other by a treating unit having a pair of tools serving to provide successive prefabricated blanks with additional fold lines in positions depending on the dimensions of commodities to be wrapped. To this end, the tools are movable toward and away from each other by a reversible motor which receives signals from photocells monitoring the height of commodities to be packed while such commodities advance toward the packing station. The photocells are mounted on a carrier which is movable up and down by the reversible motor so that the photocells come to a halt when they assume certain predetermined positions with reference to the commodities whose height deviates from the height of previously supplied commodities.

  • Patent number: 4091596
    Abstract: A method of and a machine for the simultaneous forming of and stuffing of an insert into an envelope blanked from a paper web wherein the web is intermittently advanced along a first path, scored along preselected fold lines and notched at preselected spaced intervals for defining unsevered envelope blanks having a bottom flap, a closure flap and end flaps. The bottom flap of each envelope blank is folded as the web advances along the first path to form a pocket, the leading envelope blank is stopped and registered at a preselected position, severed and charged with an insert into the pocket defined by the bottom flap. The charged envelope blank is advanced along a second path perpendicular to the first path, where adhesive is applied to the end flaps, the end flaps folded into sealing relationship with the bottom flap.

  • Patent number: 3953956
    Abstract: Apparatus for forming flaps at the top of an open-top carton after it has been packed, with the flap formation correlated to the level of the top of the contents of the carton, having means for internally scoring the walls of the carton generally at said level, means for slitting the corners of the carton generally down to said level, and means for trimming off the tops of the side walls of the carton so that they may be folded on top of the carton without overlap. In forming the flaps, the apparatus is adapted to compress the contents of the carton. The scoring means includes a set of scoring blades which fit in a carton on top of the contents and a set of external presser members for pressing the carton walls against the blade edges. The scoring blades are replaceable with blades of different sizes and provision is made for adjustment of the presser members and trimming means to operate on cartons of different sizes.
