According to an example aspect of the present invention, there is provided a cost-effective method of producing cellulose based films by introducing an intense water removal system to the process, and cellulose based films thereof having improved properties.

A device (1) for the extrusion of filaments (2) comprising a plurality of extrusion capillaries (3) arranged in at least two consecutive rows and having extrusion openings (4) for extruding a spinning solution, whereby the filaments (2) are formed, and a plurality of components (7, 8, 10) for the generation of a gas stream for producing a gas stream oriented essentially in the direction of the extrusion of the filaments (2) at least in the area of the extrusion openings (4), wherein the extrusion capillaries (3) are arranged in extrusion columns (6) which protrude from a base plate (5) and are formed in one piece with said base plate (5).

The present disclosure is directed to an apparatus and method for manufacturing a composite component. The apparatus includes a mold onto which the composite component is formed. The mold is disposed within a grid defined by a first axis and a second axis. The apparatus further includes a first frame assembly disposed above the mold and a plurality of machine heads coupled to the first frame assembly within the grid in an adjacent arrangement along the first axis. At least one of the mold or the plurality of machine heads is moveable along the first axis, the second axis, or both. At least one of the machine heads of the plurality of machine heads is moveable independently of one another along a third axis. A second frame assembly is moveable above the mold along the first axis, the second axis, or both. The second frame assembly includes a holding device. The holding device affixes to and releases from an outer skin to place and displace the outer skin at the mold.

There is disclosed a surgical sponge device comprising a sponge portion and a handle portion The sponge portion is formed from an open cell foam material having an external surface. The handle portion comprises a grip at one end thereof that compressively grips mutually opposed external surface regions of the sponge portion an edge of the sponge portion. Substantially all of the external surface of the sponge portion is formed as an uncut external surface, except for at least one predetermined region of the external surface that is located close to the grip, the at least one predetermined region of the external surface being formed as a cut external surface. Because most of the external surface of the sponge portion is uncut, it will be free of unwanted particulate material.

A method of bonding a thermoplastic component to a carpeted component and the carpeted component to cellulose-based core in a single pressing step is provided. The method includes providing a base component of a reinforced thermoplastic material, the thermoplastic component, a fibrous thermoplastic carpet or mat between the components, a sheet of thermoplastic adhesive and a core of cellulose-based material. The method also includes heating the thermoplastic component and the carpet at the interface between the thermoplastic component and the carpet for a period of time to soften the carpet. The method finally includes pressing the components, the sheet, the core and the softened carpet together under a pressure to cause the softened carpet to flow. The carpet at the interface is transformed into a solid bonding layer to bond the components together and the sheet bonds the base component and the core together to create a finished structure.

A method of manufacturing a wood-based board. The method includes applying at least one first fibre mat including a first mix comprising lignocellulosic particles and a binder on a carrier, applying a second fibre mat including a second mix including cellulosic particles and a binder on said at least one first fibre mat, and pressing said at least one first fibre mat into a base layer and the second fibre mat into a surface layer simultaneously, thereby forming a wood-based board. Also, to such a wood-based board.

Polymer-based sheet materials having a variegated appearance are provided. The polymer-based-sheet material may have a core with one or more caps. The cap(s) may be on a first primary surface, a second primary surface, and/or sides. The variegation may be within and/or on the cap and/or the core. Methods, systems, articles, and materials effective for a polymer-based sheet material having a variegated appearance are provided.

Absorbent laminated materials that include two spunbond nonwoven layers with a cellulose layer arranged in between the spunbond nonwoven layers are disclosed. The different layers of the absorbent laminated material are bonded through an ultrasonic treatment, and can further undergo an embossing step. In addition, the absorbent laminated materials may be used as disposable wiping products, among other applications.
