A device for automated packaging of articles, comprising a conveyor for feeding and transporting into the device a blank of corrugated cardboard, a pair of crease wheels for creating two longitudinal crease lines in the blank, a transversal blade or score applicator for successively creating four transversal crease lines in the blank as the blank is transported into the device, and opposite pressing members such as jaws of a press and/or pressing rollers, arranged symmetrically with respect to a center line of the device, whose lateral position is adjustable for their ends or tips to match the two longitudinal crease lines, and activated in a timely manner as the blank is transported into the device to crush the corrugated cardboard in the top, middle and bottom corners of the blank in order to make it easily foldable.

In a method for manufacturing a packaging container, a web of material including a fiber-containing material is conveyed through a preforming station and through a forming station. In the preforming station, a forming region of the web of material is preformed by cooperation of a preforming die upper part with a preforming die lower part, the forming region being deformed between the preforming die upper part and the preforming die lower part during the preforming. In the forming station, a packaging depression is formed in the preformed forming region by cooperation of a forming die upper part with a forming die lower part, wherein the preformed forming region is deformed between the forming die upper part and the forming die lower part during forming.

A cylindrical punch head (2) includes a punch face (3) and a side surface (4). The punch face extends in a radial direction about an axis of the punch head. The side surface extends in an axial direction of the punch head about a periphery of the punch face. The side surface defines a plurality of grooves (6). Each groove extends in the axial direction of the punch head. A method for shaping a paperboard bottom blank to shape a peripheral skirt portion about a periphery of the paperboard bottom blank using the cylindrical punch head.

The present invention relates to a method for manufacturing modified cellulose fibers for a moldable cellulose fiber based material, said method comprising: a) providing a chemical or semi-chemical wood pulp comprising cellulose fibers, and optionally subjecting the pulp to alkaline extraction to obtain an alkaline extracted pulp; and b) subjecting the pulp or the alkaline extracted pulp of step a) to a chemical treatment with an alkaline solution and/or an organic solvent to obtain a treated pulp or treated alkaline extracted pulp comprising modified cellulose fibers for a moldable cellulose fiber based material. The invention further relates to a moldable cellulose fiber based material comprising at least 70% by dry weight of modified cellulose fibers obtainable by the method.

Process for obtaining a container of a given shape starting from sheet material, by providing a sheet; providing a mould having a forming cavity, which defines a reference axis (R) and has a shape corresponding to the given shape of the container; positioning the sheet over forming cavity; providing a forming device having forming structure arranged on a side of the sheet opposite the forming cavity, and operating the structure for inserting the sheet into the forming cavity to deform it until a container blank is obtained having a shape approximating the given shape; and blowing a gas under pressure into the forming cavity to deform the container blank until the container with the given shape is obtained.

A stackable packaging unit comprises a molded tray including one or more compartments and a female feature. Additionally, the stackable packaging unit includes a cover attached to the molded tray and configured to cover at least a portion of at least one of the compartment(s) of the molded tray. The cover is made of folded paperboard or cardboard and includes a handle extending upward. The handle of the cover provides a male feature that is configured to fit within the female feature of a further one of the stackable packaging units that's stacked above the stackable packaging unit. The molded tray can be made of molded pulp, in which case the molded tray and the paperboard or cardboard from which the cover is made can both be recyclable. The molded tray and the paperboard or cardboard from which the cover is made can additionally or alternatively include postconsumer recycled material.

A flexible paper straw includes a paper tube which is a spiral tube having a tube wall with at least two layers and formed by using glue and paper material while the paper material is paper sheet material having at least two layers of paper, a first layer of paper and a second layer of paper; and a compressed corrugated portion which is a circular tube having parallel ridges and grooves on longitudinal sections thereof, formed on the tube wall of a part of the paper tube with a certain length and able to be bent freely.

A system for forming a pressware product comprises rollers, a scoring tool, a scoring station actuator, a forming tool, and a forming station actuator. The rollers pull the web along a path having an angle. The scoring tool receives the material from the rollers and includes a vertically shiftable scoring punch with an edge that extends about an outline of the pressware product and a striker plate. The scoring station actuator shifts the scoring tool to form a slot in the web. The forming tool receives the scored web and includes a vertically shiftable positive mold assembly and negative mold assembly. The forming station actuator shifts the positive mold assembly to press against the web and form the pressware product.

The invention concerns an apparatus for manufacturing of containers from blanks of a cardboard based material, said apparatus comprising: a container body forming unit configured to form a cylindrical container body from a substantially plane blank of a multilayer material comprising at least a supporting cardboard layer and a weldable layer; a welding unit configured to fasten an end closure to the container body, said welding unit comprising an inductive welding energy generator for melting of the weldable layer; and transporting means configured to transport a flow of body blanks to the container body forming unit, to transport a flow of container bodies from the container body forming unit to the welding unit, and to transport a flow of container bodies provided with end closures from the welding unit. The invention is characterized in that the transporting means comprises: a first movable gripping arrangement configured to grip at least two container bodies and move these container bodies simultaneously to the welding unit; and a transferring and positioning arrangement configured to transfer container bodies from the container body forming unit to the first movable gripping arrangement and to position the container bodies in a controlled manner to ensure that the first movable gripping arrangement can grip the at least two container bodies properly, wherein the welding unit is configured to simultaneously fasten an end closure to each of the at least two container bodies. The invention also concerns a method for operating an apparatus of the above type.

A method for production of a female embossing tool (6) intended for embossing a sheet element (60): provide a female embossing tool (6) with an outer layer (44) made of a material with shape-memory type properties, and the outer face of the layer has no recesses; provide a male embossing tool (5, 5′) with an outer face with at least one protuberance corresponding to at least one desired embossing relief that is to be formed on the sheet element (60) after embossing; and cooperation of the male embossing tool (5, 5′) with the female embossing tool (6) such that the outer layer (44) of the female embossing tool (6) undergoes a plastic deformation which creates at least one recess (42, 42′) of a shape complementary to the protuberance(s) (41, 41′) of the male embossing tool (5, 5′).
