Including Structural Reinforcement Patents (Class 493/89)
  • Patent number: 4926615
    Abstract: A machine for forming cardboard blanks into crates (open top containers) for transporting and storing goods, particularly plastic containers of milk. The machine has folding apparatus for folding opposed extended end flaps of the blank back on themselves to form a reinforcing structure including a ledge which, in a formed crate extends inwardly across each of two opposed ends of the crate towards the upper edges of the opposed ends. A first carriage member with suction means lifts a blank from a stack and places it at said folding apparatus. A second carriage member progresses the blank through the folding apparatus to forming apparatus where the goods are loaded onto the blank to form a mandrel and the carton is formed into a crate around the goods.

  • Patent number: 4850948
    Abstract: A laminated package insert is provided having increased compressive strength for a given weight of board stock, and being easier to erect, as compared to previously known inserts. The insert is made from two substantially identical blanks, with identical score patterns, placed face-to-face and adhered in selected areas, leaving other areas adhesive-free. The score lines are formed so that no score line has to be broken backwards during erection, thereby making erection easier, particularly for automatic insert erecting equipment. A method and apparatus for assembling the insert are also provided wherein two feeders alternately feed blanks into a hopper, each successive pair of blands being face-to-face, one blank having adhesive on selected areas of the face facing the other blank. The synchronization of the two feeders is carefully controlled, as is the settling of the blanks in the hopper, using air jets free of turbulence.

  • Patent number: 4682974
    Abstract: A slip case package for small articles includes a sleeve member and a drawer being slideably mounted therein. The sleeve member is formed by first providing a blank of relatively lightweight cardboard with graphic designs formed thereon. The blank is formed into a partially assembled sleeve portion and reinforcing member is inserted therein. The reinforced sleeve member has sufficient rigidity to act as a slip case package sleeve, but the graphics may be provided thereon with machine operations and with perfect alignment.

  • Patent number: 4650448
    Abstract: The invention is a mahcine for forming a full overlap-type shipping container from two similar blanks. A full overlap container normally has the end flaps of double thickness to withstand high top-to-bottom compression loads. This container has double thickness in both the end flaps and the laminated side walls. The machine is designed so that a first blank is transported on a main conveyor to a retractable stop located at a first combining section. Adhesive is applied to one of the side panels during transport. A second blank is then transported on a cross-conveyor to a second stop. This blank is lifted over the stop, and one side panel is positioned over the adhesive covered panel of the first blank. Pressure rolls then come into play to combine the panels. Assembly can now be completed on conventional equipment, such as folder-gluer, or may be done on an extended portion of the machine. In the latter case, the blanks are transported to a second combining station.

  • Patent number: 4613391
    Abstract: A machine for assembling polyhedron devices comprising lifting means for lifting a polyhedron blank from a supply stack. Forming means receive the polyhedron blank from the lifting means and form the polyhedron into a polyhedron shaped article. A resilient member inserter means inserts a resilient member, such as a rubber band, into the polyhedron blank on the forming means so that the resilient member will bias the polyhedron shaped article into its formed configuration. Preferably the polyhedron assembling machine of the present invention further comprises adhesive applying means for applying adhesive to the polyhedron blank in the forming means. The machine of the present invention may further comprise a polyhedron blank holder means for holding a supply stack of polyhedron blanks to be lifted by the lifting means.The invention also comprehends a method of making a collapsible polyhedron article.

  • Patent number: 4601687
    Abstract: The present is a machine for forming an inside-outside Bliss-type H-divider shipping container. It is based on an adaptation of a Moen or similar type single cycle container former. These machines employ a split mandrel which is generally in the form of a rectangular prism approximating the inner dimensions of the container. The H-divider portion of the container is held within the mandrel while the body portion is erected thereabout. Opposed plows mounted on the mandrel are adapted to fold what will become interior flaps joined to the end walls. These plows are located so that at the assembly point of the container they are entirely within the confines of the outer boundaries of the mandrel. Located in this position, they cause no interference with the erection of the body portion of the container.

  • Patent number: 4596542
    Abstract: A mandrel has its face formed to define a negative impression of reinforcing elements to be formed into the walls of a Bliss box. The reinforcing elements may comprise tubular corner posts and/or intermediate hollow ribs or posts. The mandrel is mounted in a machine frame for reciprocation along its axis so that upon full extension of the mandrel it is disposed within a die cavity in which the Bliss body panel is formed around a pair of upstanding end panels. When fully retracted, the mandrel is positioned beneath and adjacent to a pair of magazines for holding supplies of flat end panel blanks, positioned on opposite sides of a superstructure frame of the mandrel. The superstructure is fitted with spaced pairs of feed pawls, a first set of which strips the flat end panels out of the supply magazines to deliver them to an arrested position, corresponding to the retracted position of the mandrel, as a result of extension of the mandrel. Concurrently, the flaps of each end panel are partially shoed inwardly.

  • Patent number: 4283188
    Abstract: A machine for forming an H-section carton (19) from three corrugated blanks--two section blanks (21a and 21b) and a main body blank (23)--is disclosed. The machine has a generally L-shaped silhouette, with one leg of the L shape generally defining the path of travel of the section blanks and the other leg defining the path of travel of the main body blank. A supply of vertically oriented section blanks are located on opposing sides of the section blank leg. The two section blanks facing one another are simultaneously moved toward the main body blank leg, along parallel paths. The section blanks are first moved past glue heads (61a and 61b), which apply glue to the center region (22a and 22b) of the facing surfaces of the section blanks. Then, section forming mandrels (85) ram the section blanks toward one another into a U and H-section forming die (87). More specifically, the section modules first deform the section blanks into a U-shape.
