A building panel including a surface layer and a core, the core including wood fibres, and the surface layer including a substantially homogenous mix of wood fibres, a binder and wear resistant particles, the substantially homogenous mix of wood fibres including natural resins.

A sheet production line comprises: a calender for laminating and calendaring a sheet blank; a first conveying mechanism arranged at a discharge end of the calender and used for carrying and conveying a semi-finished sheet product output from the calender, where the first conveying mechanism is a traction conveying mechanism; a section cutting mechanism arranged behind the discharge end of the calender in a traveling direction of the semi-finished sheet product; and a second conveying mechanism arranged at a discharge end of the section cutting mechanism in a traveling direction of the sheet sections, where the second conveying mechanism is a non-traction conveying mechanism.

Disclosed is a process for creating an elastic film or sheet by calendaring a composition, including a polymer and a fabric. The composition may include a polymer, a cotton, or a combination of both. The calendared composition can form tough, flexible films and sheets. The film and sheet can have optical and physical properties that make them suitable as a replacement for some PVC films. Also disclosed is a composition for calendaring including a fabric and a polymer.

A method for manufacturing a composite airtight layer (20) used in the composition of a tire (30) comprises: a film (21) made of thermoplastic material is heated such that the film is able to plastically deform; the film is deformed (120) with the aid of corrugating means, the thickness of the film (21) being in a range from 0.01 to 0.2 mm, and the film having corrugations with a pitch and amplitude chosen in a range from 0.1 to 10 mm so as to give the film a given elongation capacity; the film is cooled such that the corrugated film is no longer able to be plastically deformed; and the corrugated film is coated in a matrix (22) of elastomer material, so as to form a composite airtight layer (20).

A roll forming device for plastic flooring utilizes a printed layer unwinding mechanism, a wear-resisting unwinding mechanism and a calender to laminate a substrate layer formed by an extruder, a printed layer and a wear-resisting layer into a whole. The calender includes a gauging roller group, a pre-bonding roller group and a laminating roller group disposed on a rack. The gauging roller group, which is disposed at one side of the pre-bonding roller group and linearly opposite to a discharge port of the extruder. The pre-bonding roller group includes a large roller and a plurality of guide rollers disposed around the large roller, and at least one first heating unit is disposed in the large roller or a position corresponding to an outer edge of the roller surface. The laminating roller group, which is disposed at the other side of the pre-bonding roller group.

A method for manufacturing a panel including a reinforcement sheet having the steps of: providing a first layer of thermoplastic material, providing a reinforcement sheet, laying the reinforcement sheet and the first layer onto each other, applying a second layer of thermoplastic material on top of the reinforcement sheet at a side facing away from the first layer, at least partially melting the thermoplastic materials of the first layer and the second layer, adhering the at least partially melted first layer, the at least partially melted second layer and the reinforcement sheet to each other so as to form the panel. Additionally, the reinforcement sheet and the first layer are adhered to each other by pressing them together after at least partially melting the thermoplastic material of the first layer, but before applying the second layer of thermoplastic material onto the reinforcement sheet.

Described herein are resilient floor coverings produced by using digitally printed UV-cured inks and exhibiting high adhesion properties between an ink layer and a wear layer. Also described herein are methods for manufacturing same. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.

The present disclosure provides, among other things, articles with a design material directly applied to a base material to form products with desirable properties.

In-line systems and in-line methods of producing lightweight reinforcing thermoplastic composite panels are described. The in-line systems and in-line method can be used to produce composite panels with smoother surfaces and enhanced properties in an automated manner. The produced composite panels can include a decorative layer that can provide an overall smoother panel surface compared to a composite panel lacking a decorative layer.

The invention relates to a multi-layered structure intended for producing a packaging article for storage purposes and to a method for producing said structure. The essence of the invention is that a multi-layered composition based on foamed recycled polyethylene terephthalate comprises a printed layer, a layer of foamed recycled polyethylene terephthalate having a density of from 100 kg/m.sup.3 to 900 kg/m.sup.3 and an intrinsic viscosity of from 0.5 dl/g to 1.0 dl/g, and also a layer of polyethylene or a polyethylene copolymer, or a polyethylene terephthalate copolymer. A method for producing a multi-layered composition consists in cleaning polyethylene terephthalate waste, then grinding same into fractions, followed by melting it and subsequently extruding the melt, then producing granulated polyethylene terephthalate, then extruding the granulated polyethylene terephthalate, foaming the melt, subsequently cooling the foamed recycled polyethylene terephthalate, calendering it to a thickness of from 200 μm to 1000 μm.
