FIELD: woodworking.
SUBSTANCE: invention can be used in producing the wooden crossties for the broad gage railways. The method for preventing the crosstie butt from cracking comprises in producing the composition material which consists of 50% of filings, 30% of wood fibers and 20% of polystyrene. Such composition material is flatted and the plate is produced from which the rough workpiece is cut with press, with the size equal to that of the crosstie butt, which then put upon the crosstie butt and pressed into wood. Then, the manipulator with the help of the hydraulic motor turns the crosstie to 180°, and another crosstie butt is pressed into the rough workpiece under pressure not more than 5.0 MPa.
EFFECT: service life of crossties in broad gage railways is increased.
