ABSTRACT:
Method and equipment for compacting of concrete mix when concrete products are being cast by means of a continuous method. The concrete mix is carried from the feeder device (4) forwards by means of an endless transfer unit. The compression required for the compacting of the concrete mix is produced by means of a roll (1) pressed against the transfer face (2). The compression is directed at the concrete mix by the intermediate of rigid plates (2) of a caterpillar band constituting the transfer unit, which plates are pressed against the concrete mix by means of two or more support rolls (1).
