SAWING MACHINE Russian patent published in 2006 - IPC B27B3/00 

FIELD: woodworking.

SUBSTANCE: the machine has crankshafts for plane-parallel motion of saws with a phase shift, one of the crankshafts is a drive one and is installed on the electric motor shaft. The saws are fastened on U-shaped half-frames that are positioned in the same plane and inserted in each other and the half-frames themselves are installed on the crankshafts with eccentrics made with a phase shift so that the half-frames balance each other, the bases for fastening of the half-frames on the driven crankshafts are made in the form of bearing supports enveloping the crankshafts. The drive crankshaft is positioned between the driven crankshaft is positioned between the driven crankshafts on the outer half-frame, besides, the half-frames are made of an elastic plate and at the ends are removed from each other at a distance exceeding the double eccentricity of the crankshafts, on the inner half-frame the saw is fixed, an on the outer half-frame the saw is installed for changing the gap between the saws of the outer and inner half-frames.
