Abstract

A method of cutting round timber such as logs (40) into pieces, in which method the timber is cut in the process line with parallel cuts and with cuts obliquely positioned with respect to the parallel cuts. Two or more oblique pieces are cut from the log (40) with one orientation, the same direction being maintained throughout the whole cutting process, and, when required, also spars, planks, and/or boards are cut at the same time. Cuts parallel with each other and cuts that are obliquely positioned in respect with the parallel cuts are simultaneously made by means of organs (53, 54, 55, 56, 57, 57) arranged in succession and/or side by side. The object of the invention is to afford a more economical timber cutting method through savings in raw material and labour costs, through improved feasibility of the plant arrangement, and through a reduction in the plant construction costs.
