A method and/or a machine is for tabbing a free end on a roll of sheet material. Converting a master roll of sheet material to the roll of sheet material and winding a first roll of sheet material onto a spindle at a winding position. Tabbing the free end of the roll of sheet material at a tabbing position. Where a tabber carrying a joiner are both in an initial position away from the first roll of sheet material, moving the tabber to a second position adjacent the roll of sheet material, moving the joiner into an engagement position where the joiner is engaged with the free end of the roll of sheet material. The joiner creates a tab with a combination of mechanical entanglement and heat welding. Returning the tabber and joiner to the initial positions. Doffing the tabbed roll of sheet material. The roll produced by the foregoing.

Disclosed are a scrub sponge and a preparation method therefor. The method for preparing the scrub sponge includes the operations of: obtaining a first mixture by stirring alkalizer, porogen, konjac powder, scrub granule and water, and filling the first mixture into a mold to form a preform, where the preform includes a first sponge layer; forming a parison by sequentially cooking and freezing the preform; and sequentially unfreezing, dehydrating and drying the parison to obtain the scrub sponge.

According to an example aspect of the present invention, there is provided means for maximizing the amount of cellulose content in 3D-printable bio-based thermoplastic materials and increasing temperature resistance compared to the existing bio-based thermoplastic materials used in additive manufacturing.

Method of manufacturing a regenerated cellulosic molded body, wherein the method comprises supplying a starting material which comprises cellulose and at least one foreign matter, transferring at least a part of the starting material with at least a part of the at least one foreign matter into a spinning mass which additionally contains a solvent for solving at least a part of the cellulose of the starting material in the solvent, and extruding the spinning mass to the molded body, and subsequently precipitating in a spinning bath, wherein thereby the molded body is obtained, wherein the molded body comprises cellulose and at least a part of the at least one foreign matter.

The present invention relates to a material system for 3D printing, to a 3D printing process using a lignin-containing component or derivatives thereof or modified lignins, to soluble moldings that are produced by a powder-based additive layer manufacturing process and to the use of the moldings.

A shaped article comprising a molded component configured to receive a terpene containing oil composition, said molded component formed of a plastic composition comprising cellulose ester and having an HDT of at least 95° C.

The present invention relates to a method of manufacturing a cellulosic film (cellulose film), particularly a cellulosic food packing film, especially a detectable cellulosic film, which cellulosic film comprises detectable particles incorporated therein, as well as to the cellulosic film thus produced and to its applications and usages (i.e. its use).

A method for forming cellulose products from an air-formed cellulose blank having a base and one or more forming moulds attached to the base which is arranged to rotate around a rotational axis, wherein each forming mould comprises a first mould part Wand a corresponding second mould part wherein during rotational movement of the base around the rotational axis each first mould part is arranged to engage with its corresponding second mould part in a pressing direction. The method comprises arranging the cellulose blank in a position between a first mould and the second mould forming the cellulose products in the rotary forming mould system, by applying a forming pressure between the first mould and its corresponding second mould through an engaging movement of the first mould in relation to its corresponding second mould in the pressing direction, wherein the forming moulds are rotating with the base around the rotational axis.

The present disclosure relates to a wood-plastic coated metal composite profile and a production process, and belongs to the technical field of composite profiles. The wood-plastic coated metal composite profile includes a metal core material, a wood-plastic surface layer and an intermediate layer provided between the metal core material and the wood-plastic surface layer. The intermediate layer includes unsaturated carboxylic acid modified polyolefin and thermoplastic polyurethane elastomer, inorganic filler, polyurethane prepolymer. In the present disclosure, an intermediate layer is provided between the wood-plastic surface layer and the metal core material for bonding. The intermediate layer has excellent performance when bonding with the metal, and at the same time, it can blend with the wood-plastic surface layer to a certain extent during co-extrusion. Thereby, a stable structure with core material-intermediate layer-wood-plastic surface layer is formed, and the intermediate layer has good elasticity and impact resistance, and can maintain good bonding under various environments.

A regenerated cellulosic molded body of cellulose and at least a part of at least one foreign matter, and is produced by supplying a starting material which comprises cellulose and at least one foreign matter, transferring at least a part of the starting material with at least a part of the at least one foreign matter into a spinning mass which additionally contains a solvent for solving at least a part of the cellulose of the starting material in the solvent, and extruding the spinning mass to the molded body, and subsequently precipitating in a spinning bath.
