  • Said covering elements comprise a substantially flat support element in which it is possible to identify a lower surface suited to be placed in contact with the surface to be covered and an upper, exposed surface.
  • Said elements are intended to ensure that the surfaces they cover offer suitable resistance to mechanical stress and to chemical and atmospheric agents, as well as to finish said surfaces with satisfying aesthetical results. More particularly, the function of the coverings for indoor use is to finish and decorate the surfaces of walls and floors (consisting of the exposed surfaces of said elements), thus also facilitating cleaning operations.
  • the present invention can be especially but not exclusively applied for manufacturing an element for covering surfaces, preferably walking surfaces, and more precisely for making a so-called parquet flooring.
  • the applications of the present invention are not limited to the manufacture of parquet strips.
  • the present invention can be also advantageously applied whenever it is necessary to cover a surface with elements having special anti slip, acoustic, mechanical and functional characteristics.
  • parquet flooring is a type of flooring obtained by assembling individual covering elements made of wood, also called blocks, staves, strips or panels, which are positioned adjacent to one another (for example even by means of joints) and fixed to or laid on the rough floor surface.
  • the elements for making parquet flooring can be substantially divided in two types: unfinished elements and prefinished elements.
  • prefinished elements differently from the unfinished or polished ones, are supplied already treated with varnish, oil or wax and therefore do not need any further treatment after laying.
  • these prefinished elements substantially comprise a support element in which it is possible to identify an upper surface and a lower surface and are substantially divided into prefinished solid wood elements and prefinished multi- layer elements.
  • the prefinished solid wood elements are constituted by an element obtained as an individual body in one-layer solid wood that defines both the above mentioned surfaces, while the prefinished multi-layer elements are constituted by a support element having a stratified structure, of the multi-layer or laminate type, comprising a layer in a noble material that defines the upper exposed surface.
  • the remaining layers can consist of other layers in wood or another material.
  • the elements for covering surfaces of the type described and the corresponding methods for manufacturing them pose several problems; for example, the mechanical and functional characteristics of the upper exposed surface are substantially the natural characteristics of the material (wood) used.
  • the main object of the present invention is thus to solve or at least partially overcome the problems that characterize the solutions known in the state of the art.
  • one object of the present invention to provide a solution that makes it possible to manufacture an element for covering surfaces whose exposed side has special mechanical and functional characteristics.
  • one object of the present invention is to provide a solution that makes it possible to vary the characteristics of said surface according to the need and more precisely according to the intended use of the covering element.
  • manufacture an element for covering surfaces that can be preferably used for making indoor floors and surfaces, the covering obtained therewith, as well as a method for manufacturing said element and a corresponding machine.
  • It is a further object of the invention to carry out a covering element and a surface characterized by excellent quality also from an aesthetic and decorative point of view.
  • the present invention is based on the general consideration that it is possible to vary the characteristics of the exposed surface by subjecting the material of which it is made to special treatments.
  • the present invention is also based on the further consideration that by subjecting the element to suitable processes it is possible to increase the hardness of the wood material of which the exposed surface is made (walking surface in the case of a parquet floor element) and it is possible to increase the resistance of the surface to walking.
  • the present invention is based on the further consideration that by subjecting the element to particular working processes it is possible to obtain an element whose exposed surface (walking surface in the case of a parquet floor element) has special anti slip properties.
  • the invention is also based on the further consideration that by subjecting the element to special working processes it is possible to obtain an element with particular acoustic properties (with different sound absorption, capable for example of reducing echoes, etc.).
  • the present invention is also based on the consideration that these processes do not require the removal of material (from the exposed surface), thus reducing processing residues.
  • a further consideration on which the present invention is based is that if the vegetable fibre (wood grain) that constitutes the wooden element to which the exposed surface belongs is not interrupted following the application of said processes, some characteristics (for example the above mentioned mechanical characteristics) are further improved.
  • Another consideration on which the present invention is based is that said results can be obtained by crushing, shaping and pressing the element without removing material from the exposed surface.
  • a further consideration on which the present invention is based is that in order to lend the exposed surface the above mentioned technical characteristics, by working on the wooden element of which said exposed surface is made, it is possible to give said surface also a particular and predetermined acoustic and/or aesthetic characteristic that makes it different and special compared to the exposed surfaces of the elements of known type.
  • a further consideration on which the present invention is based is that said processes should give the exposed surface (walking surface) grip properties that reduce the risk of slipping (friction).
  • a further consideration on which the present invention is based is that said processes should make it possible to vary said aesthetic and technical characteristics (grip, hardness, ecc.) as desired, according to the intended use of the manufactured element.
  • the subject of the invention is a method for manufacturing an element for covering surfaces, preferably walking surfaces, comprising the following operations: preparing a support element that defines an upper and a lower surface; said method also comprising at least one pressing operation for pressing at least part of said upper surface. Said operation thus makes it possible to carry out particular finishing processes on the exposed surface, and in particular to compact the vegetable fibres. This makes it possible to considerably increase the hardness of the upper exposed surface (walking surface).
  • said pressing operation is carried out by subjecting the exposed surface to such a pressure as not to break and/or cut the vegetable fibres that make up the wooden element to which the exposed surface belongs.
  • said pressing operation is carried out by means of a pressing element (mould) having at least one portion of its surface suited to come into contact with said exposed surface, said at least one portion having at least one part provided with grooves and/or lines and/or cuts and/or relief patterns and/or bas-relief patterns and/or engraved patterns suited to be impressed on said exposed surface.
  • the same solution makes it also possible to further vary said effects obtained on the exposed surface by varying also the pressure exerted by the pressing element (mould) on the various areas of the exposed surface (working at different depths on the exposed surface).
  • the exposed surface is also subjected to further finishing processes and in particular to a varnishing and/or brushing and/or smoothing and/or a similar process.
  • the subject is an element for covering surfaces, preferably walking surfaces, comprising a support element that defines an upper and a lower surface, said element having at least some parts of said upper surface that present a certain roughness.
  • said predetermined roughness depends on the mechanical and acoustic characteristics and is obtained through pressing.
  • the proposed solution advantage usly makes it possible to manufacture an element with an exposed surface that is more compact compared to the elements of known type. This advantageously makes it possible to obtain an exposed surface (walking surface in the case of parquet flooring) whose resistance to walking is higher than the natural resistance of the wood of which the surface is made.
  • said roughness can be obtained by pressing with a pressing element whose pressing surface is provided with special grooves and/or lines and/or cuts and/or relief patterns and/or engraved patterns that are suited to be impressed on said exposed surface.
  • the subject is a covering for surfaces, comprising a plurality of elements for covering surfaces arranged side by side, at least one of said elements for covering surfaces being manufactured according to the description provided above.
  • the subject is a machine for manufacturing elements for covering surfaces, preferably walking surfaces, comprising a support element in which it is possible to identify an upper and a lower surface, said machine comprising conveyor means defining an advance direction, suited to receive one or more support elements, said machine also comprising means for pressing at least part of said upper surface.
  • the solution proposed makes it possible to obtain an element and a surface that ensure excellent resistance and long life.
  • the element that is the subject of the invention can be properly treated and finished, for example through the application of varnishes, waxes, oils, glossy or opaque colouring agents.
  • the proposed solution makes it possible to produce an element that can be laid on and applied to the underlying surface even with traditional procedures and that is simple and easy to maintain.
  • the proposed solution makes it possible to produce an element that can be used to decorate interiors, to make decorative panels and to decorate pieces of furniture, for example table tops or mirrors or boiseries.
  • the method for manufacturing the element that is the subject of the invention allows a large number of elements of the above mentioned type to be obtained per unit of time, ensuring reduced costs, short processing times and flexibility, by adjusting the element processing methods depending on the needs, in order to obtain finishes and decorations of various types.
  • the method and the machine proposed allow mass production of said elements, considerably reducing manufacturing costs.
  • the proposed solution makes it possible to produce prefinished elements that therefore do not need further processing once they have been laid and allow the laying time to be considerably reduced.
  • the proposed solution makes it possible to produce prefinished elements having a repeatable quality that can be obtained even with specific products, for example UV curing products, that cannot be used in case of finishing after laying.
  • the proposed solution makes it possible to produce prefinished elements whose finish is more resistant to abrasion than that of the elements of known type.
