MACHINE FOR SAWING LOGS AND BEAMS Russian patent published in 1995 - IPC

FIELD: wood processing engineering. SUBSTANCE: device has framework having feeding mechanism and saw frame with a part of saw set mounted in each of them. At least two saw frames with sliding bars attached to them have common driving shaft with flywheels provided with ring- shaped protrusions placed eccentrically relative to the shaft axis. Each saw frame is connected with the flywheel by means of additional slide bar and ring-shaped protrusion. Eccentricitets of the grooves are shifted one relative to another at an angle to be calculated from a formula α=360/N, where N is the number of saw frames. EFFECT: increased production capacity; lower specific quantity of metal per structure. 2 cl, 3 dwg
