A machine for automatically manufacturing customized packaging items (I) from continuous laminar material, comprising at least one cutting and creasing unit (2) to form sheets (F) of laminar material with a plurality of cuttings and/or bendinglines (C), at least one variable-geometry forming unit (5) for forming the sheet (F) so cut and creased into a package (I) of predetermined dimensions, a multifunctional robotized manipulator (24) for automatically picking up one sheet (F) at a time from the cutting and creasing unit (2) and feeding the forming unit (5), the manipulator (24) being designed to automatically adapt to the predetermined dimensions of the packaging (I) on the forming unit (5) and interact therewith to form the packaging (I).

A multivariable perforated adjustable height box is provided with improved folding, bending, and separation of adjacent panels. The multivariable perforated adjustable height box may include a box, columns, rows, glue tabs, column scores, row scores, perforations, cuts, skips, and bundle breakers. Perforation patterns may be irregular, angled, shifted, or otherwise configured to increase usability, strength, and/or other aspects of the packaging. A method to produce a packaging device with improved folding, bending, and separation of adjacent panels using the multivariable perforated adjustable height box is also provided.

The present invention relates to material packaging made of corrugated cardboard sheet having a polygonal cross section, comprising lateral walls, a lower plane forming the bottom of the packaging, and an opposite upper plane. It comprises at least one portion (25, 26) projecting with respect to the upper plane. The bottom (30) comprises at least one surface portion (15, 16) that is cut out over a portion of the thickness of the cardboard sheet, is compressed and in the form of a non-through hollow, referred to as a hollow portion, the shape of which matches the projecting portion, in line with the latter and arranged to fit together with the projecting portion of the packaging below.

A box suitable for the packaging of a consumer product is formed by helically wrapping an elongated continuous strip of material around a mandrel to form a main body with a plurality of bands. In one embodiment, adjacent bands partially overlie one another to form a multi-paneled main body with an open top end and an open bottom end. An adhesive is disposed within the region of contact between adjacent bands to retain the shape of the main body. First and second sets of slots are formed in the main body to create flaps dimensioned to selectively enclose the open top and bottom ends, respectively. To define the flaps and promote pivotal articulation, the main body is also preferably provided with score lines. By adjusting the configuration of the mandrel, a customized box can be constructed that is sized to receive a consumer product with limited wasted space.

A creasing device for a work unit of a machine for at least creasing and possibly cutting a sheet made of a relatively rigid material, such as corrugated cardboard for packaging, fed in a predetermined work direction, includes a first creasing member mounted rotatable with its first axis of rotation transverse to the work direction, and a pre-creasing system disposed upstream of the first creasing member in the work direction, and configured to carry out a pre-creasing which progressively deforms the material of the sheet to be worked before it is subjected to a creasing operation.

A machine is provided that forms blanks of fiberboard material into containers. The machine includes a frame structure, a mandrel assembly, and a carriage assembly. One or both of the mandrel assembly or the carriage assembly can be easily removed from the frame structure such that another mandrel and/or carriage assembly having different dimensions can be easily installed in the place of the removed mandrel and/or carriage assembly.

A packaging that can be unfolded and forms a circumferentially closed ring has vertically positioned sidewalls that are connected to each other by commonly embodied corners of a spatial shape. In at least two or more corner regions, support strips extending across a corner and provided with upwardly and downwardly projecting clamping flaps are pushed onto the top edges of the bottom sidewalls, the upwardly projecting clamping flaps form between them an insertion channel extending along the extension of the support strip into which the top sidewalls can be inserted, wherein the length dimensions and the spatial shape of the sidewalls below and above the strip plane correspond with each other. The sidewalls positioned on top of each other and connected by the support strips to each other form a common packaging with commonly formed flat outer surfaces, respectively.

The present paper cup comprises a cup body, and the cup body comprises inner paper and outer paper. There are hollow bulges on the outer paper, and the outer paper forms a connecting part. The inner side of the connecting part bonds to the outer side of the inner paper, and the cup rim of the outer paper extends to the cup rim of the inner paper. In addition, the outer side of the cup rim of the inner paper bonds to the inner side of the outer paper, and both cup rims of the outer paper and the inner paper bend outward to form a double layered crimping. The manufacturing process for the present paper cup includes: paper preparation, rolling, composition, sheet cutting, forming, molding and etc.
