SUBSTANCE: cutting blade (1) comprises first and second parts (2, 3) of long frame and ledges (4) extending in crosswise direction from said firs and second parts (2, 3). Said first and second frame parts (2, 3) are interconnected by knives (5). The latter are secured at first part (2) at first points (6) of swing joint and at second part (3) of long frame swivel joint so that opposite ends of said knives (5) extend from said first points (6) and second points (7) in crosswise direction to said parts (2, 3). The latter can move relative to each other with the turn of knives 5 relative first and second points (6, 7) of swivel joint to develop cutting motion between knives every end and appropriate ledge (4).
