Method and apparatus for planing and longitudinal sawing of lamellae, in particular for laminated wood

摘要

By a method of planing and longitudinally sawing lamellae for laminated wood from wooden boards (2) being slightly curved in cross-section each wooden board (2) is arranged on a plane (1) with its hollow side (3) facing downwards. During movement along the plane (1) the lateral faces (14, 15) of the board (2) are smoothed by means of lateral cutters (10, 11), whereafter the board (2) guided by the abutment of the smoothed lateral faces against the lateral guides is sawn partially through from below by means of a lower saw (31) for the formation of a plurality of lamallae (33-39) mutually connected at their upper ends. The board (2) is then pressed downwards against the plane and planed on its upper and lower face by means of upper and lower cutters (52, 51) and thereafter sawn completely through by means of an upper saw (53) at least in the areas of the board corresponding to the areas partially sawn through from below. When the movement of the board is being guided the smoothed lateral faces are only made to abut against the lateral guides in an area of the board (2) above half the height thereof.
