FIELD: timber longitudinal sawing.
SUBSTANCE: invention relates to equipment for longitudinal sawing of timber. The cutting unit of the sawmill includes a strip unstretched saw installed in guides located above and below the material being sawn and having a saw drive from a crank mechanism. The crank mechanism includes a slider, a connecting rod and a crank with a counterweight. The slider is connected by means of a rod to a gripper fixed in the lower part of the saw, and on the rear end surfaces of the guides, support bars are fixed, with which the rear edge of the saw is in contact. The working surfaces of the bars are made of wear-resistant anti-friction material.
EFFECT: saw stroke is increased and the design of the sawmill is simplified.
