building material industry. SUBSTANCE: set has frame work with moving frame provided with oscillation exciter, changeable tray delivery mechanism and dispenser. The latter consists of dispensing bunker mounted on supporting frame and drive box feeder placed under it. Crosspiece provided with guide bushings interlocked in pairs is fixed on supporting frame end. Guide bushings embrace upper and lower bars. Lower ends of upper and lower bars are secured, respectively, on punch and matrix positioned along vertical axis of framework. Crosspiece carries power cylinders of vertical displacements, rods of which are coupled, respectively, to punch and bottomless matrix resting on moving frame through tray. Interaxial space between upper bars is by 1.25-2.5 times less than interaxial space between lower bars. Distance between surface of changeable tray and lower end of bottomless matrix and distance between punch and changeable tray when removing the forms makes up 1.2-2.1 and 2.25-3.15 of bottomless matrix height, respectively. EFFECT: enhanced efficiency. 3 cl, 3 dwg
