摘要: A vertical gang saw produces an ovoidal sawing curve when the frame has at each corner attached feet that are engaged in slide bars which themselves are attached by an extremity to the body of the machine. The lower and upper slide bars undergo a synchronized swing movement that is transmitted by small drive rods. The lower drive rods are driven by an eccentric gear moved vertically. The upper drive rods are driven by an oscillating pinion with a double cam.
