Abstract

Methods and apparatus for splitting substantially straight grained lignocellulosic material substantially along grain lines into slabs are provided. The apparatus may comprise: means for advancing material along a direction of travel, a plurality of splitter blades, said blades being spaced along the direction of travel, and being laterally spaced apart in a stepped row from a first splitter blade located to commence splitting at one side of the material, to a last splitter blade located to finalize splitting at the opposite side of the material, and support means to support the material when advancing the material in the direction of travel and past said splitter blades, said apparatus permitting the split slabs to separate away from the remainder of said material. The apparatus may alternatively comprise an apparatus for splitting substantially straight grained lignocellulosic material substantially along grain lines into slabs comprising similar material advancing means and splitter blades, but wherein the support means to support the material is compressible, said apparatus permitting the material to move laterally away from the splitter blades and from the slabs being split therefrom in response to lateral forces created during splitting.
