The present invention relates generally to a new and improved paper-based container. More specifically, the invention relates to a paper-based container that is comprised of a relatively low-density polyethylene coating on one or both surfaces of the container and at least two skive flaps, wherein each of said skive flaps is created during the manufacturing process. The skive flap further comprises at least one leading edge of the container body, and prevents unwanted moisture from entering the container and the contents of the container from saturating the paper-based material. One skive flap is preferably folded in a manner in which a portion of the outside surface of the container is adhered to the inside surface, and a second skive flap is adhered to the outside surface.

A main die-cut element is divided along a predefined division line to obtain a first die-cut element and a distinct second die-cut element. Glue is deposited on a first portion of one from between the first die-cut element and a secondary die-cut element and on a second portion of one from between the second die-cut element and the secondary die-cut element. The method includes forming an opened die-cut element of the tray plus lid type given by the combination of the first die-cut element and the second die-cut element, wherein these two elements are coupled to the secondary die-cut element, with the first die-cut element and the secondary die-cut element partly superposed and pressed to one another at the first portion and the second die-cut element and the secondary die-cut element being partly superposed and pressed together at the second portion.

An embossing tool including a female die (5) and a male die (7). A raised section (9) is formed on the female die, which corresponds to the area to be embossed. An elastic compensating element (13) is located in a recess (11) of the male die (7), which protrudes from the surface of the male die (7) by a few tenths of a millimeter. This embossing tool allows the undoing of existing embossments on a film (1).

The invention refers to a thermal sealing container (1) for transporting a food product, warm or cold, and a relative making process, wherein the container comprises a first tray (2) and a lid (3) for the closing and opening of the first tray (2), wherein the first tray (2) and the lid (3) each comprise an inner wall (4; 11) and an outer wall (5; 12) that is opposing to, and at a predetermined distance from, the respective inner wall (4; 11), wherein the first tray (2) and the lid (3) each have at least one interspace (6; 13) comprised between the respective inner (4; 11) and outer (5; 12) walls, and wherein the first tray (2) and the first lid (3) are made of respective sheets of die cut cardboard.

A method for feeding a web of printing material in a manufacturing system for producing packages, includes feeding the web from a web-fed printing press to a flat-bed machine for die-cutting or embossing while the printing press is in operation. An inserting device is used for winding the web onto an auxiliary wind-up device, moving a web-guiding element having a roller in a compensatory manner to achieve a temporary standstill of the web by converting a continuous movement of the web into an iterative movement by changing a speed of the web through changes of position of the roller, clamping the web while being cut by using a clamping unit, cross-cutting the web creating a cross cut edge by using a cutting unit adjacent the clamping unit, and inserting the web, cross cut edge first, into the flat-bed machine for at least one of die-cutting or embossing.

The invention is directed to a balanced process for extrusion of a plastic corrugated sheet or blanks, and subsequent converting of the blanks into plastic boxes. The process includes conveying the blanks to a plurality of forming stations for incrementally forming features on the blank needed for forming a box. The present process is performed at a slower speed than typical paper corrugated forming.

A device for inserting a web of printing material into a flat-bed die-cutting and/or embossing machine includes a compensator for converting a continuous movement of the web of printing material into an iterative movement of the web of printing material. A clamping unit clamps the web of printing material, a cutting unit carries out a cross cut through the web of printing material, and an inserting unit transports the web of printing material into the flat-bed die-cutting and/or embossing machine. The device advantageously allows the web of printing material to be automatically clamped, cut and fed to the flat-bed die-cutting and/or embossing machine. As a result, no further stopping of an upstream printing press is required and the amount of waste is reduced. A manufacturing system for producing packages and a method for feeding a web of printing material are also provided.

There is disclosed an alignment device for aligning a counterplate with a die plate. The alignment assembly comprises an elongate alignment pin, the pin being disposed in a mounting body; a spacer member, comprising a spacer portion and a retaining portion for retaining the spacer member to the assembly. The alignment pin, spacer member and/or mounting body are configured such that the pin can be retained in the mounting body in a first, extended, position, and in a second, retracted, position; and the spacer member is preferably retained to the assembly in both the extended and retracted positions of the pin. The pin is also configured to be drawn into an extended position by a setting tool for alignment of the counterplate relative to the die.

A method and apparatus which allow cutting-creasing rules (1) for die-cutters to be obtained from sections of cutting rules and sections of creasing rules are described. In particular, the method comprises: ⋅ (a) from a cutting rule (13) for die-cutters having height H, separating sections (2′, 2″, 2′″) provided with a cutting edge (4) and provided with coupling means (9, 10) to obtain an interlocked coupling (8) with other sections (3′, 3″, 3′″) of a creasing rule (14), ⋅ (b) from a creasing rule (14) for die-cutters having height H′, separating sections (3′, 3″, 3′″) provided with a creasing profile (5) and provided with coupling means (11, 12) to obtain an interlocked coupling (8) with other sections (2′, 2″, 2′″) of a cutting rule (13) ⋅ (c) coupling in succession the sections (2′, 2″, 2′″) of the cutting rule (13) to the sections (3′, 3″, 3′″) of the creasing rule (14) until the cutting-creasing rule (1) is obtained, the steps (a) and (b) are not carried out by tools different from each other for the cutting rule (13) and the creasing rule (14), but by the same shearing tool.
