Rotary veneer cutting machine for the conversion of a block of wood into veneers, with an improved type of device for preventing sag of the block of wood

摘要

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.
