(57) A device for truing planks and other elongated timber products has two sets of plates (4, 5) consisting of guide plates (6) forming a plank guide channel (8) between them. The guide channel (8) has a twist about the longitudinal axis (9) of the frame. This twist can be altered by pivoting the guide plates (6) of each set of plates (4 or 5) in sections. It is thus possible to give the plank guide channel (8) a different twist.
