FIELD: woodworking industry. ^ SUBSTANCE: in fractionator lattice, rods are arranged on planks, which are hingedly connected to each other in the form of polygon and are freely installed on frame. Meeting ends of rods are fixed hingedly, and opening ends are fixed freely, with entry into limiters. ^ EFFECT: device makes it possible to improve quality of wood particles fractionation by means of rational selection of distance between neighbouring rods, which corresponds to range of fractionating wood particles length, as a result of which strength of manufactured wood boards to static bending is increased. ^ 2 dwg |
