APPARATUS FOR CUTTING SEVERING OF A THIN BOARD FROM SQUARED TIMBER

In an apparatus for cutting severing of a thin board (22) from squared timber (6) which is moved on a guide surface (4) against the cutting edge (16) of a blade (14) the adjustment of the distance between the guide surface (4) and the plane (24) parallel thereto extending through the blade cutting edge (16), and thus the adjustment of the apparatus to different board thicknesses to be produced, is effected by relative adjustment of the blade cutting edge (16) to the guide surface (4) in an inclined plane (36) which forms an acute adjustment angle (.alpha.) to a normal (32) to the guide surface. With this arrangement, with a changed board thickness adjustment of the apparatus the distance between the blade cutting edge (16) and a counter pressing edge (30) in the cutting direction is automatically adapted. Furthermore, in a preferred embodiment with this adjustment the width of the exit guide channel (between the surfaces 26 and 50) for the separated board (22) can be simultaneously set to the new thickness.
