Definitions

  • This invention relates to methods of producing sheets of wood veneer, and to the wood veneer so produced.
  • the method according to the present invention is concerned with producing veneers having varying flowers (i.e., the patterning of the wood) from a common wooden block, the flower of the veneers so produced running substantially normal to the grain of the wood.
  • Sheets of wood veneer are conventionally cut directly from a log which may have been squared or quartered and the quality of the veneer obtained depends entirely on the growth of the tree from which the log was taken. In general, only a comparatively small proportion of the available trees yield logs from which high quality Wood veneers may be sliced, and accordingly many proposals have been made for producing sheets of wood veneer which have the appearance of having been cut from a tree, the growth of which has been regular.
  • a method of producing a sheet of wood veneer comprising the steps of cutting a plurality of veener laminations, forming from the veneer laminations a V-shaped block in which the grains of the laminations are in a direction across the V of the block, and slicing sheets of Wood veneer from the block with a knife, the sheets of veneer obtained having smooth surfaces suitable for polishing.
  • each of the veneer laminations comprising the block has the configuration of a V with the grains of all the laminations in a direction across the V of the block.
  • the grain of a lamination is across the V of the block, it is meant that the direction of the grain is substantially straight down one arm of the V to the apex of the V and then substantially straight up the other arm of the V.
  • the profile of the actual block is immaterial provided that the individual laminations have the configuration of a V as described.
  • the block may itself have the shape of a V or it may first be trimmed to a substantially rectangular shape, or indeed to any shape which is appropriate and suitable for the veneer slicing machine by which the final veneers are to be sliced from the block.
  • a preferred embodiment of the invention provides a method of producing a sheet of wood veneer comprising the steps of cutting a plurality of veneer laminations, ar-
  • the sheets of veneer may be sliced from the block by the knife of a flat cutting machine acting along the length of the V of the block.
  • the term along the length of the V of the block indicates the direction at right angles to that previously denoted by the expression across the V of the block.
  • it is particularly to be noted that it is the length of the V which is referred to and not the length of the block.
  • the length of the V is a fixed direction in a block irrespective of the dimensions of the block, so that sometimes the length of the block will be in the same direction as the length of the V of the block, while alternatively the longer dimensions or length of the block may be at right angles to the length of the V of the block.
  • the sheets of veneer are sliced from the block by the knife of a flat cutting machine acting at an angle to the length of the V of the block.
  • the slicing of the veneers from the block is commenced at the apex of the V of the block.
  • the sheets of veneer are sliced from the block by the knife of a flat cutting machine acting substantially at right-angles to the length of the V of the block, whereby the sheet of veneer obtained has a herring-bone pattern.
  • the V-shaped block is mounted between the chucks of a rotary cutting machine with the grains of the veneer laminations extending from one chuck of the machine to the other, and veneer laminations are sliced from the block with the blade of the rotary cutting machine'
  • the veneer laminations sliced in this way may be cut from a continuous sheet of veneer.
  • the invention also comprehends a fabricated sheet of wood veneer comprising a slice of veneer cut from a block formed in a V-shape by a plurality of natural wood laminations which have been bonded together with the grain of the wood in all laminations extending in the same direction and across the V of the block, the slice of veneer having smooth surfaces suitable for polishing.
  • the invention further comprehends a V-shaped block of veneer laminations in which the grains of the laminations are in a direction across the V of the block.
  • FIGURE 1 shows diagrammatically a glued stack of veneer laminations in a press having male and female V-shaped jigs
  • FIGURE 2 shows in perspective the V-shaped block prepared by pressing the stack in FIGURE 1,
  • FIGURE 3 shows in perspective the inverted V-shaped block of FIGURE 2
  • FIGURE 4 shows the veneer produced by cutting the block of FIGURE 2 by a knife in a plane parallel to ABCD
  • FIGURE 6 shows the veneer produced by cutting the block of FIGURE 3 in 'a plane parallel to M.N.O.P
  • FIGURE 7 shows a veneer lamination cut from a wooden flitch in a direction from bottom to top of the tree
  • FIGURE 8 shows diagrammatically a'V-shaped block according to the invention, mounted between the chucks of a rotary cutting machine, and
  • FIGURE 9 shows a veneer lamination cut from the block of FIGURE 8 by the blade of a rotary cutting machine.
  • a glued stack of veneer laminations 1 is prepared in the usual manner, namely by stripping sheets of wood from a log which has preferably been steamed to aid cutting, cutting the sheets of wood into laminations of a predetermined size and free from imperfections, selecting a number of veneer laminationsand applying glue to the veneer laminations in the conventional manner and placing the laminations in a stack, so that the grain and the flower of the wood in each veneer lamination runs in the same direction throughout the stack of veneer laminations.
  • the stack of veneer laminations 1 is placed on the lower female V-shaped jig 2 in a press with the grain of the wood in a direction across the V of the lower jig 2.
  • the stack of veneer laminations is then compressed by applying pressure to the male V-shaped jig 3 and compressing the block to set the glue.
  • the glue may be any suitable synthetic resin adhesive, but in each case the glues are allowed to set without the application of any heat or steam.
  • FIGURE 2 The V-shaped block prepared in this manner is shown in FIGURE 2, and the natural flower and grain are indicated by numerals t and 5 respectively.
  • the block 1 is inverted and according to the flower of the veneer desired, the block may be tilted at any angle cc between and 90 to a knife shown generally at 6, and the block is then cut by the knife acting at the appropriate angle a tothe length of the V of the block.
  • the knife 6 is the knife of a flat I cutting machine.
  • FIGURE 7 For reasons of comparison a sheet of wood cut from a wooden flitch is shown in FIGURE 7.
  • the grain 8 of the wood runs substantially parallel to the flower 7 of the wood when the flitch is cut in the direction of the grain, i.e. in the direction from the bottom to the top of the tree.
  • FIGURE 9 As the block 9 is revolved in the rotary cutting machine, a series of veneer laminations is cut from the surface 11 of the block 9.
  • the figure 12 which is present on a veneer lamination 13 cut from the block 9 in the rotary cutting machine is shown in FIGURE 9.
  • the trimmed block 9 of veneer laminations As shown in FIGURE 8, the trimmed block 9 of veneer laminations, the grain of which laminations is in a direc tion extending from one chuck 10 of the rotary cutting machine to the other chuck 10', is mounted eccentrica-lly between the chucks 10. Consequently a series of veener laminations 13' is cut from the block and each of these veener laminations 13 will have a slightly different width which decreases for each successive lamination because the block 9 is becoming smaller in size.
  • the block 9 may alternatively be mounted symmetrically between the chucks 10 so that a continuous sheet of veener is sliced from the block by the blade of the rotary cutting machine. This continuous sheet of veneer will have a repeating pattern of FIGURE 12 on it and may then be repeating pattern offlgure 12 on it and may then be subsequently cut into a series of veneer laminations of a desired size.
  • the V-shaped block has a single V and the grain of the veneer laminations runs across the V of the block, the length of the V of the block being substantially linear. However, if desired, some further shaping may be impressed on the length of the V of the block, whereby variations in the figure of the veeners sliced from the block is obtained.
  • the veener laminations from which the V-shaped block is made may be all of the same colour, or may include veneer laminations of different colours so that specially controlled coloured figured veneer can be obtained.
  • the coloured veener laminations may be natural colour variations or may include artificially coloured veener laminations.
  • the veeners produced by the method of the pressure invention are mechanically strong and pliable and moreover, when polished, give rise to an extremely smooth and regular surface.
  • a method of producing a fabricated sheet of wood vineer each having a grain direction comprising the steps 0 cutting a plurality of natural wood veneer sheets to a selected uniform shape;
  • the veneer having smooth uniplanar exposed surfaces suitable for polishing.
