ABSTRACT:
The invention relates to a method for manufacturing a veneer web composed of individual veneer strips of finite length and width which are pre-cut from a peeled veneer sheet. According to a known method, the strips are cut from the veneer sheet in random sizes, depending on the presence of faults or quality variations of the veneer sheet, whereupon they are combined in a tesselated pattern. An object of the invention is the provision of a method permitting veneer webs of practically any desired width and length to be produced in an economical manner with optimum utilization of the faultless and acceptable-quality portions of the peeled starting veneer material. To attain this object, the invention provides that the peeled veneer is cut to strips of equal width, that the absolutely non-usable strips are discarded, that the usable longitudinal sections of partially usable strips are trimmed of such strips, that the fault-free strips and the fault-free strip sections are joined to form continuous ribbons, and finally that these ribbons are joined transversely of their longitudinal direction to form a veneer web of a desired length and width.
