Definitions

  • the invention refers to a development of the prior patent No. 9456 A/84 filed by the same inventor on 11 July 1984.
  • a board for wooden floors is made up of an upper layer with viewable face, mostly of valuable wood, matched with a lower layer having a plywood construction and thus with sheets having the fibres pattern both orthogonal and parallel to that of the valuable layer; the valuable layer - intended to form the viewable face - has a longitudinal fibres pattern and the lower plywood layer has transverse grooves being thus orthogonal to the fibres pattern of the upper layer.
  • the lower layer has the fibres patterns of the external sheets or thicknesses perpendicular to those of the upper valuable layer and, therefore, parallel to the grooves.
  • the lower plywood layer has five sheets or thicknesses, the intermediate thickness and the two external ones of said lower plywood layer having fibres being transverse in respect to those of the upper valuable layer.
  • the lower plywood layer has the two outer thicknesses or sheets with a fibres pattern transverse in respect to that of the upper valuable layer, and the intermediate sheet - single or double with a fibres pattern parallel to that of the upper valuable layer.
  • the proposed solution is particularly suitable for boards being relatively wide in respect to their length.
  • the above mentioned transverse grooves may be deeply cut to involve at least most of the thickness of the lower layer. More particularly, the grooves may have a width of the order of at least 3 mm and such a depth as never to penetrate the upper layer and not to indent the adhesive veil which unites the valuable- wood board to the lower plywood layer.
  • the side cogs and slots for the installation joint are formed in the lower plywood layer.
  • the prior patent relates also to a process for realizing the above mentioned wood boards for floors, having advantages as for rapidity and economy in the production.
  • the process for realizing the above described boards for floors and, especially, relatively short and wide boards comprises: making a multi-layer panel to form a structure of plywood type; matching said panel with a plurality of elements made of a material - mostly valuable - intended to form the upper layers of the boards, said elements being spaced between them and with the fibres patterns orthogonal to those of the outer layers of the plywood panel; making grooves - mostly by a milling operation - in the lower layer, parallel to the fibres patterns of the outer plywood layers and, therefore, perpendicular to the fibres pattern of said elements; and the separating operation to create the boards and the operation to form the joint cogs and slots.
  • a floor board is made up of an upper layer 21 of valuable wood and a lower layer 23 consisting of two external plywood sheets 23A, 23B, and two intermediate sheets 23C.
  • the fibres pattern of the layer 21 and of sheets 23C is longitudinal, that is, lying in the direction fL of the board length; the fibres pattern of sheets 23A and 23B is orientated in the transverse direction fT.
  • the cross sections taken on planes perpendicular to the fibres are conventionally squared and the cross-sections parallel to the fibres pattern show a wide, wavy hatching.
  • transverse grooves 25 are cut out parallel to the direction fT and suitably spaced apart for the function already pointed out.
  • the depth of the grooves does not go beyond the glueing surface 27 between 21 and 23B, and may also not go beyond the glueing surface 29 between 23B and 23C.
  • the boards have rib projections 30 and channel recesses 32 - shown only in Fig.2 - to form the joints. Both the projections and the channels are formed from the layer 23.
  • Fig.2 shows a five-layer plywood, a central layer 23E bezng interposed between the thicknesses or sheets 23C; the sheet or thickness 23E has the fibres pattern parallel to that of thicknesses 23A and 23B.
