Abstract (en)
[origin: EP0327139A2] A device for producing prismatic or truncated pyramidal beams from tree trunks (4) by edging the same with the aid of two pairs of mutually opposite working tools (40 to 43) is described. The working tools (40 to 43) are displaceably guided on a frame (44) transversely to the longitudinal extent of the tree trunk (4). Driven transport rollers for advancing the tree trunk are provided on both sides of the frame (44). <IMAGE>
