Abstract
Five processes for cutting teak wood timber so that the resulting logs have at least one straight-line grain surface and minimal surface area showing buds. Logs or thin sections thereof when aligned and glued together form boards or planks with straight-line grain surfaces.
Claims11
A process for manufacturing a teak board having at least one surface with straight-line grain, comprising the stops of:
- cutting a teak timber determined by a circumferential outer surface across its annual ring thereby formning an end with a generally planar surface bounded by a circumferential perimeter, said planar surface bounding first, second, third and fourth sectors having non-bud structure, and first, second, third and fourth sectors having bud structure, each bud and non-bud sector having an inner heartwood portion and an outer sapwood portion, said inner and outer portions contiguous along a boundary, each bud sector contiguous to and disposed between two non-bud sectors, each non-bud sector contiguous to and disposed between two bud sectors, each sector having a vertex proximate to the pith area and terminating at said outer surface;
- cutting longitudinally through said planar surface along a first plurality of generally parallel lines and a second plurality of generally parallel lines generally orthogonal to said first plurality of lines, each line determined by preselected endpoints on the planar surface, thereby forming a plurality of logs with a preselected common cross-section, each log having at least one side with straight-line grain;
- and
- forming a board by aligning and contiguously attaching the logs so that at least one of the composite surfaces so formed has straight-line grain.
