A method for processing planar material webs made of a fiber-containing material is disclosed. The planar material webs are fed as material web portions or endless material web, for the production of three-dimensional products. Before a material web is pressed for shaping, the material web is preformed three-dimensionally by deforming the material web in at least one direction substantially without stretching or compressing.

The present disclosure relates to a process for the pretreatment of fibrous material in a production process for producing three-dimensional products, to a pretreatment chamber for the pretreatment of fibrous material, and to a fiber molding plant having at least one pretreatment chamber. By pretreating relatively dry fiber material, the shaping step in a manufacturing process can be significantly improved and the choice of product geometries can be increased.

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 processing method of a pulp molded container cover is provided, belonging to the field of pulp molding technologies. It solves the defects such as the existing unreasonable design. The processing method of the pulp molded container cover includes steps: S1, wet blank forming, step S2, hot-pressing molding, and step S3, roll-pressing. The sealing performance and processing efficiency are improved.

A method and apparatus for pleating or otherwise shaping a web are described herein. The method and apparatus may have numerous applications. In some embodiments, the method and apparatus are used in the formation, filling, and sealing of unit dose packages for consumer products. A method and apparatus for forming sealing two moving webs together, which webs have portions that are non-planar are also described herein.

A creasing device is provided that includes a counter-rotating male drum and female drum. The male drum carries a conventional creasing ring with a central rib flanked by shoulders. The female drum comprises a central channel aligned with the creasing rib on the male drum; and a pair of projecting lateral ribs on each side of the central channel that are aligned with the shoulders on the male drum. The lateral ribs press a sheet of the card or paper stock against the shoulders of the creasing ring to better define the edges of the crease and to reduce the tendency of a printed coating on the stock to crack during subsequent folding. The pair of lateral ribs may be provided by a pair of inserts. Alternatively, both ribs and the central channel may be provided by a single insert.

A pressing module and method for forming cellulose products from an air-formed cellulose blank structure, where the pressing module comprises a forming mould with a first mould part and a second mould part configured for interacting with each other for forming the cellulose products from the air-formed cellulose blank structure in the forming mould. The first mould part and/or the second mould part are movably arranged relative to each other in a pressing direction parallel to a longitudinal direction of the pressing module. The first mould part and the second mould part are at least partly configured for being arranged in an overlapping relationship in the longitudinal direction during forming of the cellulose products. The first mould part comprises a first mould part section and a second mould part section arranged in connection to the first mould part section.

A method for producing a cellulose product from an air-formed cellulose blank structure includes the steps of providing a cellulose-based material to a mill, milling the cellulose-based material, and providing an air-formed cellulose blank structure, wherein the cellulose blank structure is air-formed from cellulose fibres.

The objective of the present invention is to provide a method of forming a pressed paper piece by deep drawing a sheet of blank that is primarily made of paper in use of a punch and a die, and a production apparatus for implementing the method, whereby no distinguishable wrinkles are formed in upright portions of the pressed paper piece. The method of producing a pressed paper piece according to the present invention, implemented when deep drawing a sheet-like blank that is primarily made of paper in use of a punch and a die, includes maintaining a predetermined gap between a first blank holder and the die in an outer peripheral region of a process portion of the blank and applying a pressure to a radially inner region thereof via a second blank holder, thereby reducing wrinkling by an effect of integrated functions exerted in both regions of the blank.
