The method for the production of curved furniture components comprises: an overlapping step of a first panel of wooden, plastic or metal material, of at least one intermediate separating layer and of a second panel of wooden, plastic or metal material for obtaining a flat semi-finished product having a perimeter edge; an interposition step of a polyurethane type adhesive between the intermediate layer and the first panel and second panel by hot dispensing of said adhesive on the surfaces of the first and the second panels which are adapted to be associated with the intermediate layer or by hot dispensing of the adhesive on the surfaces of the intermediate layer which are adapted to be associated with said first panel and second panel; a cold shaping step of the semi-finished product for obtaining a curved component; and a spraying step of a water-based auxiliary substance between the intermediate layer and at least one of the first panel and the second panel, subsequent to the interposition of the adhesive.

A method for laminating an assembled sandwich structure consisting of a functional part (4) and one glass article (5) separated from an outer surface of the functional part by a laminating film (6) by heating with electromagnetic radiation in a vacuum is described. In the method equal temperatures of all sandwich components are provided by selection of the optimal radiation frequencies. The optimal vacuum level is provided following the laminating film temperature.

A method for forming a multilayer plastic sheet material (1) for floor and/or wall panels, wherein a first polymer mass comprising a rigid PVC is melted under pressure and is passed through an extruder head at a specified discharge rate in the form of a plastic strand in sheet form that is provided with one or more layers so that a multilayer plastic strand is formed, which is passed to two or more rolls of a finishing stand, which processes the multilayer plastic strand into a sheet of defined thickness, which is then led away via a transport device to a sawing device to be cut to the desired length, wherein, after the plastic strand in sheet form leaves the extruder head, it is first passed between a top roll and a bottom roll of a roughing stand, wherein the speed of the rolls of the finishing stand and the rolls of the roughing stand is synchronized with the discharge rate of the plastic strand in sheet form from the extruder head, so that said plastic strand is processed without stress.

Textiles are re-cycled by grinding and scatter-laying onto a needle-punched web optionally containing low-melting material, followed by laying a second needle-punched web over the scattered layer and re-needling the three layers before applying heat or heat and pressure to activate the low-melting ground material present within the layers. Additional low-melt ground material is optionally blended into the ground textile if low melt components are absent or insufficient to bond the composite. The ground material is driven and dispersed into the surrounding web layers with at least part of the material being adjacent the two outer surfaces. The physical properties of the composite can be adjusted by selecting suitable combinations including but not limited to needling stroke depth, needling density, needle gage, low-melt content, heat finishing conditions, and relative layer weights. The final composites can optionally be reintroduced into the original end use and include significant percentages of recycled material.
