Definitions

  • the present invention relates to a method for producing molded surface panels for furniture and panels and furniture thus obtained.
  • the invention is particularly useful for carrying out central panels which are successively square framed for producing furniture doors.
  • the object of the present invention is to obviate the above-mentioned disadvantages and particularly to produce door central panels at a very low cost.
  • the invention as claimed solves the problem of how to carry out furniture door panels with variable thickness, the preferred range being 5 to 35 mm thickness, by means of the following method:
  • the method comprises carrying out said first and second mixing of the wood saw dust in the same blender by mixing on vertical axis cylindrical chamber with radial arms rotating at about 1500 r.p.m. speed, by immediately successive inlet first of the polyol-carbon naphtha compound product and then of the diisocyanate product, coming from two separate tanks which disembogue by means of two separate ducts, into said blender.
  • the method comprises effecting said pressing at a temperature of about 5 0°C.
  • the method comprises carrying out said pressing between die and counterdie wherein the lower plane is movable and supports passing a plurality of thrust lifting vertical pins positioned under a movable matrix die with the upper surface having the shape to be given to the corresponding panel surface, which slides vertically in a matrix guide box open upwards for receiving the punch of the upper counterdie hung fixed on the upper plane, a fixed plane being arranged under said vertical lifting pins so that:
  • the method comprises carrying out said pressing for about 1 minute if the panel to be obtained is bare, i.e. not covered, or for about 2 minutes if the panel is covered with said sheets.
  • the invention provides the realization of a panel (A) comprising a polymerized mixture of wood saw dust with polyurethane (1) covered above and below with sheets of wood (2,3) the outside surface of which is molded by pressing in a press (D) where polymerization reaction and wood saw dust mixture in one block occur.
  • the covering sheets (2,3) may also lack when the furniture door is to be lacquered.
  • the panel thus obtained (A) is then mounted on a door frame (B) in successive operations which are not related to the present invention.
  • the production system provides a mixing unit (C) comprising a wood saw dust feeder, such as a screw feeder (5) which supply wood saw dust from a wood saw dust tank (4) and pours same into a hopper (6) provided with motorized (7') mixer-conveyor (7), which causes wood saw dust to flow in dosed amount into a vertical mixing chamber (8) provided with motorized (9') vertical rotating blendor (9).
  • the mixing chamber (8) is provided with various opposite joints at various levels of mixture fluid inlet (10) which engage two respective ducts (11',12') so that the respective mixture fluid products flow in adjustable manner in controlled amount from separate independent tanks (11,12) one containing mixed polyols compounds together with carbon naphtha and the other containing diisocyanate compound.
  • the press (D) includes a fixed upper plane (22) and a fixed lower plane (17) which supports cylinders (18) which passing rods (18') lift and lower a movable overhanging lower plane (16) provided with passing vertically movable stripper pins (19), the lower die being fixed thereon, consisting of a matrix (20), with molded upper surface for molding the surface of the panel to be pressed (A), vertically guided movable within a guide box (20'), while the upper counterdie (21) is fixed under the upper plane (22).
  • Pressing is carried out during lifting of the movable lower plane (16) and panel (A) extraction occurs during lowering, since the pins (19) beating on the fixed lower plane (17) get out upwards urging the matrix (20) with the pressed panel (A) outside the die guide box (20').
  • a 407x394x15 mm specimen panel obtained by means of the above-mentioned method has been subjected to WET/DRY TEST at "CATAS CENTRO REGIONALE ASSISTENZA TECNICA SETTORE SEDIE MOBILI LEGNO", a Regional Laboratory of the Chamber of Commerce Industry Handicraft and Agriculture of Udine, (IT) in the Laboratory Section of SAN GIOVANNI AL NATISONE (UD), IT.
