A method of actuating a trimming apparatus or directly a sorting apparatus for elongate workpieces and an installation for optimising the output of lumber such as in particular planed material using the method afford an increased degree of automation and thereby optimised and reproducible sorting results if each piece of the planed material (12) which is discharged rapidly from the planing machine (14) in the longitudinal direction firstly receives applied thereto only an identification code (18), preferably in the form of a bar code, with which is associated the result of pattern evaluation for surface defect location and classification. On the basis thereof an optimisation computer (20) determines optimum lopping and trimming parameters for the identification code (18). that is to say for the specific item of the planed material (12), in order to saw out of the planed material (12) a piece (12') of the maximum possible length , with the lowest possible of level of flaws, that is to say of optimum quality. Using the corresponding information for the control (25) of the lopping and trimming saw (13) the optimisation computer (20) actuates a clear-text producer (26) which. during the transverse transportation movement of the planed material (12) to the saw (13), such transportation movement being very slow in comparison with the longitudinal transportation movement. applies the relevant processing symbols to the planed material (12) which is identified by the identification code (18) thereof, which symbols are then fed by the clear-text reader (29) into the control (25) for the saw (13); unless transposition into visual recognisable symbols is entirely eliminated and the trimming control (25) is fed from the computer (20) directly in code-dependent manner.
