The device includes guide bars (4) for joining two plates (3,5) and permitting parallel movement between them. The plates, between which planks are clamped, have milled-out areas (2) at each end which fit over a guide rebate (1). - Movement of the planks in pairs is permitted by a movable counterpiece (6). Pins are produced by repeated movement, with intermediary displacement laterally along the guide rebate, over a milling instrument (8). |
