A blank for being formed into a container. The blank has a marginal area that includes a plurality of score lines for facilitating forming of the blank into the container. The score lines are positioned to facilitate formation of the container. A forming tool has features to facilitate forming the blank into the container.

The pack includes a box structure defining an inner cavity. A side of the box structure is sealed by a first adhesive. A lower end of the pack is sealed by a second adhesive connecting a rear surface of a lower panel of a front panel to a front surface of a lower glue panel of a back panel. The upper portion of the pack is circumscribed by perforated lines that cause the upper portion to remain connected to the tuck panel if the upper end of the pack is opened. The blank for forming the pack includes an upper portion of a back panel that is circumscribed by perforated lines. The method of making the pack includes applying an adhesive to the upper portion of the back panel and connecting a rear surface of a tuck panel to the upper portion.

A machine for forming a container from a blank of sheet material is provided. The blank includes a reinforcing panel assembly for forming a reinforcing corner assembly. The machine includes a hopper station for storing the blank in a substantially flat configuration and a forming station for forming the blank into the container. The forming station includes an initial forming station that rotates a first portion of the reinforcing panel assembly with respect to a second portion of the reinforcing panel assembly, and a secondary forming station having male and female forming members with shapes corresponding to an interior shape and an exterior shape of the reinforcing corner assembly, respectively. The male and the female forming members are configured to form the reinforcing corner assembly by compressing together the first and second portions of the reinforcing panel assembly.

The composite structure includes a fiber-containing layer, such as a fiberboard layer or other layer having fibers from natural and/or synthetic sources, and a mineral-containing layer covering the fiber-containing layer. The fiber-containing layer and mineral-containing layer can be shaped, sized and manufactured such that the composite structure formed therefrom is capable of being machined to form a storage article. The composite structure has advantages in that it can improve whiteness, opacity, ink adhesion, materials reduction, barrier properties, recyclability, and printability. The composite can reduce polymer mass requirements for heat seal, barrier, and fiber adhesion. Further improvements include economics, pliability, and flexibility that is increased over the pliability of the fiber-containing layer alone.

A folding arrangement intended for folding of a continuous flow of box blanks. The folding arrangement includes: a feeding arrangement adapted to generate the continuous flow of box blanks through the folding arrangement and a folding unit. Also is a folding machine including the arrangement. Also is a method for adjustable folding of box blanks passing through the folding arrangement.

A method for forming a container from a blank assembly including a tray blank and lid blank includes folding a first portion of the blank assembly about at least a first face of a first mandrel to form a partially formed container, and transferring the partially formed container towards a second mandrel using a transfer assembly that extends through the first face of the first mandrel. The method also includes transferring the partially formed container from the first mandrel to the second mandrel along a pair of guide rails extending between the first mandrel and the second mandrel, wrapping a second portion of the blank assembly about at least a first face of the second mandrel to form the container, wherein the first face of the second mandrel opposes the first face of the first mandrel with respect to a vertical direction, and ejecting the container from the second mandrel.

A vacuum belt conveyor sequentially delivers sheet articles to a digital printer. The sheets are held in position by vacuum on the underside of the sheets through apertures in the belt and covered by the sheets. A plurality of independent plenums on the underside of the belt have chambers respectively communicating with rows of apertures extending along the belt. Vacuum is selectively applied from a manifold only to the plenum chambers that supply apertures that are covered by the sheets so that the ink from the printer will not be directed from its intended position on the sheet by vacuum from adjacent uncovered belt apertures.

In a folder-gluer, push-out forces by an air cylinder and a push-out spring mechanism are set such that: (1) when downstream portions of first and fourth panels are passing through a second bending plate, the second bending plate is pushed outwardly in a width direction by the push-out forces to extend the downstream portions of the first and fourth panels in the width direction; and (2) when upstream portions of the first and fourth panels are passing through the second bending plate, the second bending plate is pushed back inwardly in the width direction by the resistance force applied to the second bending plate by the first and fourth panels so as not to extend the upstream portions in the width direction, and wherein the push-out forces are not varied by a control while the first and fourth panels are passing through the second bending plate.

A box erecting device for folding a box is disclosed herein. The box erecting device includes a folding plate and a lid erecting system. The folding plate is configured for erecting a box, and a folding notch including a first edge and a second edge is formed in the folding plate. The first edge is configured for erecting a first dust flap of the box, and the second edge is configured for erecting a second dust flap of the box. The lid erecting system is disposed adjacent to the folding plate and is configured for erecting a lid of the box. The lid erecting system includes a tab funnel and a folding tool. The tab funnel includes a ramp for retaining the dust flaps while closing the lid. The folding tool includes a hooked ramp for causing a distal end of the lid to be inserted into the box.

A system and method for a double glue joint is provided. The box is movable between knockdown and assembled configurations. In the knockdown configuration, the box includes a plurality of co-planar panels connected to one another, with a first and last panel each having a free end having a tab. One of these tabs, along with a portion of the panel adjoining the tab, are coated with adhesive. The box is movable to an assembled configuration by folding the panels relative to each other by one or more score lines until the free ends of the first and last panels meet. Utilizing the adhesive, the tab of the last panel is secured to an exterior surface of the first panel while the tab of the first panel is secured to an interior surface of the last panel, thus forming a double glue joint with interior and exterior connections.
