METHOD FOR MACHINING ELONGATED WORKPIECES MADE OF WOOD， PLASTIC AND THE LIKE， AND MACHINE FOR CARRYING OUT SAID METHOD

In the method， the workpieces are clamped between at least one upper and one lower clamping jaw (17， 18 and 19， 20) of a first clamping unit (1， 2) so that at least one side of the can be processed. The first workpiece is transferred to a second clamping unit (1， 2)， which has at least one upper and one lower clamping jaw (17， 17 and 19， 20)， which is connected to the second clamping unit (1 ， 2) is clamped in such a way that further machining can be carried out on the workpiece. The workpieces are clamped horizontally during the transfer between the two clamping units (1， 2)， with at least one clamping unit (1， 2) being clamped vertically up to the horizontal clamping by the clamping jaws (17 to 20). With horizontal clamping and vertical clamping released transverse to the longitudinal direction， the workpieces are displaced and then clamped vertically by the clamping jaws (17 to 20) of the same clamping unit (1， 2) or the clamping unit (1， 2) receiving the workpieces. Then the horizontal clamping is released. As a result， the workpiece is always clamped during the transfer from the first to the second clamping unit (1， 2)， so that the risk of bending or twisting of the workpiece， for example due to internal stresses， is avoided.
