Abstract: A cutter block for rotary veneer cutting machine for converting a block of wood into veneers is position-wise registrable with respect to the frame of the machine which supports it, so as to permit regulation of the cutting angle of the cutter, the cutting edge of which is parallel to the axis of rotation of the block of wood.To this end, the cutter block is mounted on the machine frame along a registration fulcrum pin which is not coincident with the cutting edge of the cutter and to which is imparted a combined movement of rotation and translation.Control means for obtaining such movement are associated with the registration fulcrum pin.

Abstract: A rotary veneer cutting machine for conversion of a block of wood into veneers comprises a device for preventing the block of wood from sagging which consists of a first and second set of pressure rollers which act respectively on the upper half and lower half of the block of wood. The first set of rollers is mounted along a beam which is translatable in the plane that contains it, from which beam there extend articulated arms carrying the said second set of rollers. With the said beam and said articulated arms there are associated guide means and actuators which keep the said sets of rollers in contact with the block of wood as its diameter decreases.
