The method and arrangement work according to the principle that the contours in the longitudinal direction of the piece of timber (10A) are first measured by measuring devices (22, 23) which exert minimal pressure on the piece of timber, after which the piece of timber is advanced to at least one control device (32, 33) which is arranged immediately adjacent to the processing machine and acts laterally upon the piece of timber with a considerably larger alignment force. Measurement signals from measuring devices are processed in a known manner in a computer (D) from which the order signals are sent to the control unit with a determined delay. The control device operates both as an alignment device, by aligning the piece of timber to the necessary feed attitude calculated in the computer, and as a control device in the stricter sense of the term by controlling the piece of timber while it is being fed into the processing machine. The control devices may be positioned to one side of the measuring devices. <IMAGE> |
