The present invention relates to a stable mat (10) based on thermoplastic materials, comprising a core of compacted plastics (14), the cohesion of which is provided by spot thermal fusion (18) in the core of the mass, and a skin obtained by surface thermal fusion and/or a thermoplastic shell (12) firmly attached to the core by localized thermal fusion. Such a mat may serve as bases for civil engineering constructions, for the distribution of loads in the case of loose, unstable, or marshy soils, the stabilization of embankments or of unstable soils, earthquake-resistant protection of foundations of structures and composition of absorbent ballasts of railroads. They may also be used for the manufacture of prefabricated road elements.

A method for producing a separator plate, where thermoplastic polymer material and a powder of electro-conductive filler, ECF is kneaded at a kneading temperature above a glass transition temperature for the thermoplastic polymer material but below a melting temperature for the thermoplastic polymer material in order to provide a malleable but not molten compound and for causing fibrillization in the thermoplastic polymer material prior to hot-compacting the sheet in a press-form to form a separator plate. A production facility for practicing the method is also disclosed.

A method is provided for manufacturing recyclable inorganic paper, which has a composition comprising 60-85 wt % mixture of natural inorganic mineral powders, inorganic glass powders, and sand powders, 5-40 wt % bonding agent of polypropylene (PP), and 1-5 wt % assisting agents, through the following steps: feeding and mixing of the constituents of the composition; stirring and mixing the composition; pressing to cause bi-directional extension of the composition so as to form a sheet; subjecting the sheet to operation of a high density squeezing machine for further mixing and pressing the sheet; reversely turning and shaping the sheet for further extension of the sheet; and continuous compression and extension of the sheet to induce further bi-directional extension of the sheet in both lateral and longitudinal direction and to control thickness of the sheet.

A method for manufacturing a board element, such as a floor element, including an at least partially recycled board layer. The method includes providing a pre-processed material from at least one weight-reduced preformed board element, preferably being obtained by removal of material from a rear side thereof, wherein the pre-processed material includes a thermoplastic material, and providing a virgin material including a thermoplastic material. The method further includes applying heat and pressure to the pre-processed material and the virgin material in a double-belt press to form the board layer, and forming a board element comprising the board layer. Also, a corresponding assembly for manufacturing of a board element.

In this molded surface fastener, an engaging element includes a columnar stem portion, and micro pawl portions protruding outward from an upper end outer peripheral edge of the stem portion in a plan view of the engaging elements. A pawl width dimension of the micro pawl portions is smaller than a line segment connecting two points on the upper end outer peripheral edge of the stem portion. The micro pawl portions protrude toward a base portion. This molded surface fastener has a high peel strength and a shear strength with respect to a female surface fastener.

The invention describes a method for manufacturing a plastic drain sheet, and a plastic drain sheet. For the purpose of manufacture, a sheet-like main body having a first surface and a second surface, spaced apart therefrom by a base sheet thickness, is provided. Grooves are introduced into the first surface and mating grooves are introduced into the second surface. The mating grooves and the grooves cross one another at crossing points. Through-openings between the grooves and the mating grooves are formed at the crossing points.

In this molded surface fastener, plural engaging elements having a stem portion and an engaging head portion formed integrally on the stem portion are standing on the base portion, at least one pawl portion having a pawl width dimension narrower than a width dimension at a boundary between the stem portion and the engaging head portion is protruded on an outer peripheral edge part of the engaging head portion, and a back surface of pawl of the pawl portion is formed at different angles with respect to a back surface of head portion of the engaging head portion. Such a molded surface fastener of the present invention has a substantial engaging force with respect to a female surface fastener and can make a texture of its surface comfortable.

The invention relates to a method for continuously producing an embossed web (2) from a primary web (3) having a surface face (3A) and an opposite back face (3B), wherein the primary web (3) is subjected to an operation for embossing the surface face (3A) using a heated embossing cylinder (5), the method being characterised in that the embossing operation comprises at least a first step of compressing the surface face (3A) of the primary web (3), said primary web (3) being in contact with the surface of the heated embossing cylinder (5) on at least one portion (Pc) of the perimeter of the latter, using a compression band (6) in surface contact with the back face (3B) of the primary web (3).
