<p>A method for guiding an unedged board or like workpiece into an edging machine, or for aligning the board therewith, involves determining the useful width of the board (1) with the aid of a pair of mutually co-acting jaws (17) which are brought into gripping engagement with the board, so as to grip the board therebetween. Those parts of the jaws (17) intended for gripping engagement with a board comprise bodies of resilient material, and the gripping force is so adapted in relation to the resiliency of the material that any wane present on the board (1) is pressed into the resilient material. The distance between the jaws (17) is then used as a measurement of the useful width of the board (1) when aligning the board with the edging machine (2). The invention also relates to an arrangement of apparatus and devices for guiding or aligning an unedged board in accordance with the above.</p> |
