Definitions

  • parallel cut boards or squared timber are obtained as cut raw material.
  • the refined is processed by shaping cut or planing. specially manufactured wood end product.
  • This radial cutting process fulfills the contemporary task listed under II. In the following way.
  • the debarked, cylindrical round wood rolls (1) are pushed longitudinally axially through a feed pipe by continuous pressure and constant feed speed of the circular saw and leave after the cutting process as radially separated, core-free and. finished external wall molded parts in a discharge pipe the machining circular saw.
  • Two or three or four substantially different, finished outer wall molded parts are created in one operation and in a circular saw machine at the same time.
  • the variety of molded parts is an advantage for the market, because they are a novelty on the market.
  • the objective single work step is the substantial reduction in production costs.
  • the extended motor shafts (2,3) of the two drive motors (4,5) are at an angle of 3o degrees, more or less,
  • the drive motors (4,5) are arranged in the direction of the log axis along such a distance that the cannot touch circular saw blades (6,7) with their tooth tips up to the center of the wood.
  • the tangential cutting saw blade (8) also rotates on the circular saw shaft (2) and the saw blades (9, 1o) rotate on the circular saw shaft (3) and cut flat areas on the round timber (1).
  • the radial cutting saw blade (11) and the tangential cutting saw blades (8, 13, 14) rotate on the motor shaft (2).
  • the saw blade (13) creates a radially standing conical round cut.
  • the changing round wood diameter of cheaper small wood from 8 cm to 16 cm in diameter can be processed by simply changing the circular saw blades, without any noteworthy wood waste, into the required thicknesses of the outer wall profiles (B, C, E, F,) and thus optimally used.
