摘要

A process for producing beams of square cross-section from tree boles or the like is characterized in that plano-convex slabs are severed in parallel to the hart zone of the boles. An apparatus for performing the process is characterized in that the boles (2) are supported by height-adjustable supports (9, 10) in such a way that the heart zone (8) is congruent with the preferably horizontal feeding direction of the bole (2). Thereby, the thus-produced square beam (7) is defined by planes parallel to the heart zone.
