ABSTRACT:
A glide-casting machine for the manufacturing of hollow concrete elements. The machine is movable in relation to a casting base and comprises means for feeding concrete mix onto a number of screw feeders with vibrator sleeves constituting extension of each screw feeder. In addition, the machine comprises external vibrating means. In connection with each screw feeder there are provided on one hand, two guide plates parallel to the axis of the screw feeder, which guide plates follow the shape of the screw feeders in the bottom portion of the screw feeders. Between the guide plates there is an elongated space parallel to the axis of the screw feeder so as to allow concrete mix to fall straight onto the base on a substantial portion of the length of the screw feeder. On the other hand there are provided flow plates which follow the shape of the outermost screw feeders from above and from the sides.
