    Abstract: The invention relates to a method and apparatus for manufacturing a fiber-reinforced concrete product, in which method at least one auger feeder (5) is used for propelling concrete mix through a defined extruder cross section (20, 21, 23). In the manufacture of the product, at least two different materials are produced suitable for use in the manufacture of a concrete product, at least one of the materials containing reinforcing fiber and both materials being dosed onto the auger feeders (5). The apparatus has two containers for the materials and during the feeding the relative proportions of the materials are controlled so that the ratio of the amount of the fiber-reinforced material to the amount of the unreinforced material is such that gives the end product an inhomogeneous distribution of the reinforcing fiber in the volume of the product, whereby at least one portion of the product volume has a greater volumetric content of the reinforcement than that of an equivalent volume in at least one other portion of the product. The final cast product contains desired amounts of reinforcement on areas where bigger loads are to be imposed on the product.

    Abstract: A means of extruding machine for continuous moulding of prestressed hollow elements and slabs of concrete, of the kind comprising an extruding machine provided with wheels (2, 4) resting on a floor or steel bench (5). The machine comprises a front operational unit, a suitably vertical hopper (10) for supply of fresh concrete, and which lowermost opens into a horizontal, in direction rearwards directed moulding chamber (12). Through the moulding chamber extends a stationary, horizontally directed support shaft, which at the rear end supports a forming tube (20) for the concrete. On the support shaft is rotatably supported a feeding screw (16, 14) for feeding and compressing the concrete in rearward direction towards the forming tube (20), and a vibrator (44) situated in connection with the forming tube (40) and optionally vibrators situated elsewhere on the machine. In accordance with the invention, the forming tube (20) including the accenter (64) is connected to the rear end of the support shaft via an elastic damper member (50), such that the vibrator (54, 64) is mechanically separated from the remaining part of the extruding machine.

    Abstract: Изобретение относится к промышленности строительных материалов и предназначено для производства керамических изделий пластического формования методом экструзии. Шнековый пресс содержит корпус с внутренним каналом и шнек, размещенный на приводном валу внутри канала, за которым далее по ходу движения материала, на вал жестко посажены лопастные ножи, чередующиеся с неподвижно закрепленными в корпусе поперечными формующими дисками, перекрывающими не более 20% сечения канала. Каждый последующий нож повернут на оси приводного вала относительно предыдущего ножа на угол, составляющий половину угла между лопастями. Площадь, перекрываемая лопастями каждого ножа, составляет от 70 до 90% сечения канала пресса. Угол наклона лопастей ножа к плоскости формующего диска составляет от 15° до 20°. Первым и последним по ходу движения материала установлены формующие диски. Повышается качество керамических изделий за счет предотвращения образования свили и создания в керамической массе однородной по всему поперечному сечению формуемого бруса структуры повышенной плотности.
