The invention relates to a press roller for a roller press, in particular for briquetting, compacting or grinding granular material, having a roller core (1) and a roller sleeve fastened to the exterior of the roller core (1), said sleeve being composed of a plurality of segments (2), distributed over the circumference, with mutually facing lateral faces (3). The segments (2) have clamping shoulders (5) which extend around the front faces and have first clamping surfaces (8). The segments (2) are releasably fastened at each front face to the roller core (1) by means of at least one fastening ring (6), said fastening ring fitting over the clamping shoulders (5) of the segments (2). The front faces (12) and/or clamping shoulders (5) of the segments (2), in the front face edge regions associated with the lateral faces (3), have outer material reinforcements (13) which protrude outwardly relative to the first clamping surface (8) in the radial direction and/or relative to the front face (12) in the axial direction and define, together with the clamping surfaces (8), pocket-type recesses (14) in between them in the circumferential direction, second clamping surfaces (9) of the fastening ring (6) resting against said pocket-type recesses.

Said fastening ring fits over the clamping shoulders (5) of the segments (2). The fastening ring (6) is or can be clamped against the segments (2) by means of axially parallel clamping bolts (7). Each segment has at least one axially parallel opening for the clamping bolts which, relative to the extension in the circumferential direction, is arranged between the two lateral faces (3) of the segment (2).

A method is provided for producing discrete three-dimensional cellulose products from an air-formed cellulose blank structure in a rotary forming mould system. The method includes providing an air-formed cellulose blank structure, wherein the cellulose blank structure is air-formed from cellulose fibres; transporting the air-formed cellulose blank structure to a the rotary forming mould system; feeding the air-formed cellulose blank structure to a position between a first mould part and a second mould part, and heating the air-formed cellulose blank structure; forming the three-dimensional cellulose products from the air-formed cellulose blank structure in the rotary forming mould system, by pressing the heated air-formed cellulose blank structure with a forming pressure.

The present invention is directed to a process to produce agglomerated lignin with a controlled particle size distribution. The agglomerated lignin is essentially free of dust so that the risk of dust explosion is greatly reduced.

The present invention is directed to a process for preparing coating compositions containing up to 100% bio-based content. The coating compositions are used for coating metal, paper and wood substrates in various applications. The process for preparing the coating composition comprises the steps of providing lignin, wherein the lignin is agglomerated and has a particle size distribution such that at least 80 wt-% of the agglomerates have a diameter within the range of from 0.2 mm to 5.0 mm, dissolving the agglomerated lignin in an organic solvent, and mixing the solution with a crosslinker to obtain a coating composition.

The invention provides a multilayer-structure absorbent core for a disposable absorbent article, and a method for preparing the absorbent core, wherein the absorbent core is compacted and formed by each layer; its surface presents a grid-shaped groove; the depth at the intersection point of the grid-shaped groove is bigger than that at the non-intersection point thereof. The invention adopts a new synchronous split-level process; that is, a linear grid-shaped trapezoid-shaped compaction mechanism, of which the height is smaller than that of a circular-platform structure, incompletely compacts the absorbent core and separates the absorbent core into numerous small convex spaces, while a circular-platform structure carries out the dot-shaped compaction for the absorbent core. Under the conditions that the liquid-absorption functions of a deflector layer and a reservoir layer are maintained, the movement of polymer water-absorption material is completely limited while the strength of a core body is enhanced. The invention adjusts the structure of the core body and a process of preparing it, thus facilitating the improved multilayer structure to have more liquid-absorption amount, faster liquid-absorption speed and increased strength.

The present invention relates to a process for the production of abuse-proofed, thermoformed dosage forms containing, apart from one or more active ingredients with potential for abuse and optionally physiologically acceptable auxiliary substances, at least one synthetic or natural polymer with a breaking strength of at least 500 N.
