  • the thermosetting resin can be, for instance, a phenolic resin.
  • Plywood is manufactured from veneers which have been peeled from a log and dried to a desired moisture content. Some of the veneers are passed through a glue spreader where a thermosetting adhesive is applied on both sides of the veneer. Veneers are stacked on top of another in a preselected order and orientation to produce a laid-up assembly of veneers, so called plywood billet. The plywood billet is sub ⁇ jected to hot pressing which is carried out between heated metal plates. During hot pressing the veneers are consolidated and the thermosetting adhesive be- tween them is cured. After hot pressing plywood is sanded to reach a desired thickness. Finally, a coat ⁇ ing can be applied on one or both surfaces of plywood.
  • the coating material can be applied in liquid form or in the form of a cellulose film, or paper, impregnated with the coating material. Further, at least one of the coated surfaces can be provided with a surface profiling to increase the friction of the surface.
  • Hot pressing has two main objectives: to press the glue into a thin layer over (and into) each veneer, and to activate the thermosetting adhesive. At the same time, water contained in the adhesive evapo- rates and penetrates into the veneers. The veneers first swell and then, after the vapor starts to re ⁇ lease from the plywood billet, shrink.
  • Hot pressing can be carried out with a step ⁇ wise or a steplessly lowering pressure.
  • a high peak pressure is applied for a short time to bring the veneers together and to spread the adhesive between the veneers. Then, the pressure is reduced to about half of the peak pressure. Finally, a low end pressure is applied in order that water vapor can es ⁇ cape from the plywood billet.
  • the temperature of press plates is typically around 130°C.
  • the pressure and duration of pressing depend on the number of veneers and, thus, the thickness of plywood.
  • the target is to raise the temperature in the center of the plywood billet to at least 100°C so that all the free water can be made to evaporate.
  • the number of veneer sheets stacked into a plywood billet is generally selected so that a prede ⁇ termined plywood thickness can be reached after hot pressing.
  • the fine adjustment of plywood thickness is then to be carried out by sanding plywood in a finish ⁇ ing step.
  • Figure 2 clearly shows that the second, third and fourth ve ⁇ neers from the surface are compressed the most. In this test all the veneers were cross-bonded. If the second, third and fourth veneers were oriented (with the same grain direction) , their compression would have been even higher.
  • High density veneers are able to absorb more water vapor than low density veneers.
  • high density veneers compress less during the high pressure stage (pressure over 1 MPa) when they dry.
  • the compressibility of the selected high density veneers is also more predictable than the compressi ⁇ bility of randomly selected interior veneers.
  • the compressibility of individual veneers has been found to depend on their density and their loca ⁇ tion in the veneer lay-up. Hence, if veneers of low density and veneers of high density are randomly used at a position where the compression of the veneer tends to be high, the variation of plywood thickness after hot pressing can be expected to be high.
  • Plywood according to the present invention is preferably manufactured from veneers with a density of at least 550 kg/m 3 , preferably 570 kg/m 3 (measured at moisture content of 3%) .
  • Suitable wood species in- elude for instance, birch and beech.
  • Preferably all the veneers of plywood are of the same wood species.
  • the veneers used as oriented veneers can have an aver ⁇ age density which is at least 3%, preferably at least 4%, more preferably at least 5% higher than the aver- age density of the veneers used as interior veneers.
  • the density of the plywood according to the present invention can be at least 630 kg/m 3 , prefera ⁇ bly at least 650 kg/m 3 , more preferably at least 670 kg/m 3 (measured at moisture content of 10%) .
  • the aver- age density of the oriented veneer layers can be at least 2%, preferably at least 4%, more preferably at least 5% higher than the average density of the inte ⁇ rior veneer layers.
  • Figure 1 shows one possible embodiment of plywood structure. It has to be noted that the struc ⁇ ture need not be fully symmetrical if warping of ply ⁇ wood can be prevented by other means. It is of higher importance that the number of oriented high-density veneer layers is the same next to each surface veneer layer.
  • Figures 3(a) to 3(f) schematically show six further embodiments of plywood.
  • hor ⁇ izontal strokes denote veneer layers having their grain direction oriented parallel to the plane of pa- per
  • vertical strokes denote veneer layers having their grain direction oriented at perpendicular to the plane of paper.
  • Figure 3(a) schematically shows plywood hav ⁇ ing a surface veneer layer A on each side, four ori- ented veneer layers B next to each surface veneer lay ⁇ er A, and 11 interior veneer layers C which are cross- bonded.
  • the grain of the oriented veneer layers B is perpendicular to the grain of the surface veneer layers A.
  • Each interior veneer layer C has a grain direction which is perpendicular to the grain direction of its two closest veneer layers.
  • the average density of the oriented veneer layers B is higher than the aver ⁇ age density of the interior veneer layers C.
  • the total number of veneer layers is 21.
  • Figure 3 (b) schematically shows plywood which differs from plywood of Figure 3(a) in that the number of oriented veneer layers B next to each surface ve ⁇ neer layer A is three. The total number of veneer lay ⁇ ers is 19.
  • Figure 3(c) schematically shows plywood which differs from plywood of Figure 3(a) in that the number of oriented veneer layers B next to each surface ve ⁇ neer layer A is two. The total number of veneer layers is 17.
  • Figure 3 (d) schematically shows plywood which differs from plywood of Figure 3(a) in that the number of interior veneer layers C is an even number. Consequently, there needs to be two interior veneer layers next to each other arranged to have parallel grain di ⁇ rection. The veneer layers having parallel grain direction need not be the middlemost veneer layers. The total number of veneer layers is 20.
  • Figure 3(e) schematically shows plywood which differs from plywood of Figure 3 (d) in that the number of oriented veneer layers B next to each surface ve ⁇ neer layer A is three. The total number of veneer lay- ers is 18.
  • Figure 3(f) schematically shows plywood which differs from plywood of Figure 3 (d) in that the number of oriented veneer layers B next to each surface ve ⁇ neer layer A is two. The total number of veneer layers is 16.
  • the number of interior veneer layers C can be different from those shown in Figure 1 or Figures 3(a) to 3(f) .
  • a minimum of three interior layers C is need ⁇ ed to produce a cross-bonded plywood structure.
  • the number of veneer layers is at least 9, preferably at least 13, more preferably at least 15.
  • the number of veneer layers can range from 11 to 15.
  • the number of veneer layers can range from 17 to 25.
  • Sanding reduces the thickness of surface ve ⁇ neer layers A, thus the total thickness of plywood is also reduced.
  • the surface ve ⁇ neer layers A tend to form an unstable base for coat ⁇ ing.
  • the instability of the surface veneer layer can lead to cracking of the surface veneer layer A or de- lamination of the coating 2. If the thickness of the surface veneer layer A can be kept as intact as possi ⁇ ble by minimizing the need for sanding, a uniform and stable coating 2 can be obtained.
  • the predictability of plywood thickness after hot pressing can be improved by selecting the oriented veneers so that their average density is higher than the average density of the plurality of interior ve- neers. Consequently, the compressibility of the ply ⁇ wood billet comes up to expectations, less extra ve ⁇ neers are needed to reach a desired plywood thickness, and sanding of plywood to reach a desired nominal thickness can be kept at a minimum.
  • the present invention allows minimizing mate ⁇ rial losses due to sanding. Normally the sanding loss is about 0.6-2 mm, but the new method enables lowering the sanding loss to about 0.3-1 mm.
  • Plywood according to the present invention is suitable for use as flooring in the cargo space of a freight transport vehicle or a freight transport unit of a freight transport vehicle, which flooring is fastened to a chassis of the freight transport vehicle or to a chassis of the freight transport unit of a freight transport vehicle.
  • a trailer or an ⁇ other similar freight transport unit of a freight transport vehicle is loaded and unloaded with a fork- lift, which is driven on and off the cargo space of the trailer.
  • the surface of the flooring is subjected to repeated abrasion, wear and tear and alternating stresses. Further, the surface of the flooring, which consists of two or more plywood panels joined side by side, must be free of steps or dents.
  • Plywood according to the present invention is also suitable for use in the manufacture of concrete forms in which plywood panels are fastened to a frame- work, which supports plywood against the pressure of concrete poured on the opposite side of plywood.
