A collapsible article comprising a plurality of foldably interconnected foldable sections/modules. The foldable sections can be part of cylindrical or conical surfaces. They can also be in the form of closing sections. When the foldable sections are part of tubular surfaces, either cylindrical or conical, they consist of four polygonal surface segments. The polygonal segments are curved/round in unfolded state and have a flat or approximately flat shape in partly folded and folded states. The folding process usually involves an abrupt transition between the unfolded and folded positions which makes the unfolded article almost as stable as non-foldable equivalents. The folding process usually requires application of force on the edges that form valley creases during folding.

An article or portion of an article comprising a combination of at least two foldable modules that mutually hinder either their folding or unfolding during normal operation until additional force is applied on particular spots along the mutual foldable edges that connect the modules. The article or the portion of the article not only can perform almost as well as non-folding equivalents but also can have the advantages that foldability offers. Such foldable modules can define not only tubular cylindrical shapes but also conical ones and mixtures between them. They can also be built as closing collapsible modules.

A fiber capsule and a method of compression molding a fiber-based packaging capsule, includes the steps: a raw capsule of a loosely bonded fiber mat is formed, which capsule has an opening; the raw capsule of the loosely bonded fiber mat is positioned on the inside of a substantially rigid mold having inner surfaces defining the molded outer surfaces of the fiber-based packaging capsule; the loosely bonded fiber mat is compression molded by the insertion of a pressurizable compression member through the opening. The pressing device is pressurized at a temperature of 150-250 degrees C.. The compression molding takes place by reshaping the reshaping pressing device and pressing the inside of the capsule against the inner surfaces of the rigid mold so that a cohesive fiber-based packaging capsule is obtained.

A carrier comprises a lifting assembly and a box assembly. The lifting assembly defines at least one platform surface and at least one shoulder portion. The box assembly defines at least one intermediate slot. The at least one intermediate slots receives a portion of the main member such that the at least one shoulder portion engages at least a portion of the box assembly to transfer downward loads on the box assembly to the lifting assembly.

A method and device for producing boxes is provided. The boxes include a cut-out shape in the form of the bottom or the lid, with a lateral wall. The lateral wall is formed from a strip having a beginning, an end, and connection tongues. Then, the beginning of the strip is applied and fixed to the lateral surface of a cylindrical female mould having a cross-section corresponding to the cross-section of the box, by means of a male mould. Then, the female mould is turned. The strip is sucked onto the lateral surface and held in place by means of a vacuum. After an adhesive has been applied to the beginning or end of the strip, the beginning and end of the strip are stuck together. Then, a cut-out shape in the form of the bottom or the lid is pressed onto the connection tongues.

The invention relates to a method and a device for producing three-dimensional molded parts from a continuous sheet of a flat, plastically malleable fiber material via deep drawing with a stamp and an associated die, wherein the fiber material between the stamp and the die can be reshaped via a relative movement.

The object of the instant invention is to offer a method and a device for producing three-dimensional molded parts in which the reshaping is done via deep drawing from a cut-to-size section in the continuous sheet and which leads to a high reshaping ratio. The problem is solved by connecting the round, rectangular, oval or irregular cut-to-size section for the molded part during the deep-drawing process to the continuous sheet of fiber material via at least one web and otherwise separating it from the continuous sheet via at least one stress-easing cut; a reshaping ratio, as the ratio of the diameter and the depth, of greater than 0.2 can be realized.

A method and device for producing boxes from paper or cardboard is provided. The boxes include a cut-out shape in the form of the bottom or the lid, with a lateral wall stuck thereto. The lateral wall is formed from a strip having a beginning, an end, and connection tongues are bent by up to 90 C. Then, the beginning of the strip is applied and fixed to the lateral surface of a cylindrical female mold having a cross-section corresponding to the cross-section of the box, by means of a male mold. Then, the female mold is turned. The strip is sucked onto the lateral surface and held in place by means of a vacuum. After an adhesive has been applied to the beginning or end of the strip, the beginning and end of the strip are stuck together. Then, a cut-out shape in the form of the bottom or the lid, which has previously had adhesive applied to the periphery thereof, is pressed onto the connection tongues. Once the adhesive has hardened and the vacuum has been stopped, the finished box can be removed from the female mold.

A moulding apparatus for forming an object from a dose of material derived partially from natural fibres, having a forming region delimited by a lateral surface extending around a central zone of the forming region. The apparatus includes a first half-mould defining the forming region, including a transverse surface and the lateral surface defining a forming cavity, a second half-mould mutually movable with respect to the first half-mould along a moulding axis so as to be inserted into the forming cavity for shaping the dose, and a compensation device which can be positioned at a variable distance from the transverse surface through a mutual movement of the compensation device and the forming cavity, so as to determine a final size of the object to be formed as a function of the volume of the dose inserted into the forming cavity.
