2068648 9108880 PCTABS00005 A method of and a device for working a longitudinal groove in natural wall logs. Drawbacks of the prior art methods of industrial working of logs are uneconomic use of raw material and unsuitability for working a longitudinal groove in a natural log. Up till now, only a manual working of a dead log in particular has been possible. The object of the invention is to eliminate these drawbacks. By means of the working method and the device of the invention, the form of a lower log (9) is copied to the longitudinal groove of an upper log (8) by using a parallel mechanism (27, 28, 30; 24, 29, 33) mounted on bearings on a carrier (22) moving on guides (21) parallel with the logs (8, 9). Each half of the longitudinal groove is worked independently.
