  • the panel according to the invention may also have differently patterned surface embossings, when no effect of the imitation leather type is desired.
  • the coating layer has a softness and a tactile effect quite similar to those of imitation leather lining, without the need of intermediate layers or connecting the supporting and the coating layer or for providinge the desired soft-touch effect.

  • the panel according to the invention has lower costs, lower weight and a better appearance and touch effect, respecting the minimun thickness requirements of the field. From the point of view of the method for fabricating the panel, it is to be considered that the above mentioned panel allowas very simple and low costs treatment of coatings made of at least two different layers . As the following disclosure will describe in greater detail , the panel according to the invention also lends itself advantageously to the manufacture of panels with differentiated coatings as regards the aesthetic effect, particularly colour and type of embossing, and tactile effect, particularly softness.

  • the panel according to the invention or rather its coating layer, has a very good behaviour during the shaping of the panel, as it has no bleaching effect .
  • the invention also relates to a method for the fabrication of the above described coated panel , comprising a phase for the extrusion of a sheet composed of polyolefin polymers, which is chronologically simultaneous to or separate from a phase for the extrusion of the supporting layer and a phase for the application of the coating sheet on at least one side of the supporting layer on exit of the latter from the extruder, by lamination.

  • the silicon have a granulometry of about 0,1 to 0,4 ⁇ m.
  • the coating sheet and the supporting layer are both obtained by extrusion and the coated panel is obtained by lamination of the coating sheet on the supporting layer on exit of the latter from the extruder.
  • the panel so obtained is then subjected to the embossing of the coating layer, in order to obtain a surface structure similar to that of leather or of the so-called imitation leather, and eventually of different and any type.
  • Advantageously embossing is executed in a subsequent panel shaping phase, to obtain the finished product, like vehicle lining, or similar.
  • the method for fabricating the panel is very simple, fast and economic, and efficiently avoids all the problems derived from the application of traditional imitation leather coatings. Partiularly the shift of the pattern embosing phase at the same time with shaping the panel in a later shaping phase, allows to lower the manufacturing costs and to obtain better final appearance visually and relatively to the touch effect.
  • the thicknesses of the coating layer required to obtain the aesthetic and tactile effects, as well as the softness resembling those of imitation leather are very small, and are included between 50 and 3000 ⁇ m, preferably between 200 and 600 ⁇ m, thus being smaller of some orders of magnitude than the typical thicknesses of traditional imitation leather lining.
  • composition of the resin chiefly made of polyolefin polymers may comprise different types of additional agents, like, for example, pigments to provide for different colours, antiscratch additives and/or stabilizers against UN rays.

  • the upper layer 3, with missing zones 103, coinciding with the zones in which the lining must be differentiated may have very small thicknesses, lower than those of the at least partially continuous underlying layer, for the fact that the softness effect of the lining is substantially provided by the lower coating layer 2.

  • the missing zones, or apertures 103 may also intersect, or overlap partially, thus allowing for matchingc that have been hardly reachable up to this moment, unless at very high costs.
  • the single coating layers are applied following the method described hereinbefore, i.e. they are extruded and then laminated on the supporting layer, one on top of another.
  • the pattern of the differentiated coating may reach considerable levels of complexity, not involving particular additional difficulties or costs, apart from a different configuration of the cutting die tools.

  • the supporting layer 2 may be laminated at the same time as the two coating sheets 2, 4, which are next to each other with respect to the direction of their transfer.
  • this procedure may be extended to provide a coating layer composed of a ' plurality of different strips.
  • the procedure indicated in figs. 3 to 5 may be obviously combined with that according to fig. 2, so that, for example, the lower coating layer may be formed by at least two strips with different aesthetic and tactile or softness effects, onto which at least one upper layer is laminated, with at least one missing zone, obtained by die cutting, which extends at least partially on all the strips of the underlying layer, or, alternatively or in combination, with more missing zones which extend simultaneously in coincidence with a single strip or at least a portion of the strips.
  • the advantages derived from the panel according to the invention and from the method for its fabrication are self-evident.
  • the current trend for manufacturing differentiated lining always involves applying and fixing the differentiated coating layer on the supporting layer substantially while shaping the panel, which implies remarkable complications both for the construction of molds and for the preparation of the lining.
  • the latter is to be prepared previously, by joining together the different coating parts, and by introducing them into the mold, while overlapping the supporting layer and being retained in a frame.
  • the panel according to the invention may be also easily used for the fabrication of shaped lining panels, in which the outer coating of the panel comprises areas with an aesthetic aspect and a tactile effect of the imitation leather type and other areas coated with fabric or other material .
  • the use of the panel according to the invention allows for easier, faster and cheaper fabricating operations.
  • the current procedure is in fact quite similar to the above disclosure regarding the panels with differentiated coating, as for colour or other aspects of the same material, since a portion of the coating is replaced by fabric or similar.

Then, a suitable groove along the perimeter of the coating made of fabric or another different material, provides clean junction lines, when the depth of said groove is such that the edges of the coating made of different material, like fabric or similar, may be housed inside it.
