FIELD: wood-working industry. SUBSTANCE: sawing machine has drive with toothed wheels 2 for rotating of circular saw 1. Wheels 2 are positioned at outer side of saw 1. Slots 7 between teeth 6 of circular saw have geometry coinciding with that of toothed wheels 6. Saw 1 is positioned perpendicular to direction of force of gravity in symmetry with bed. Segment-shaped guides are disposed on drive casing so that they adjoin side surfaces of saw 1. Spacer wedge is secured on drive casing to be reciprocated by levers. Wheel teeth are formed as rollers 9 mounted on shafts 10 for rotation and engagement with slots 7 between teeth 6. EFFECT: increased efficiency, simplified construction and enhanced reliability in operation. 2 cl, 3 dwg |
