ABSTRACT:
In a method and assembly for trimming a stack of veneer sheets, both lengthwise and transverse cutting lines are determined in advance by means of a director light projecting a line. The position data of the determined line are processed by a computer to control the feed to a cutting plane. Alternatively, the cutting lines are marked. The stack is firmly clamped between conveyor belts of a mechanism by which, after the first lengthwise trimming, the stack is turned upside down, after the same procedure for determining the cutting line, fed to the cutting plane. The transverse trimming is effected in similar fashion.
