A vibratory extruder for molding fiber concrete troughs comprises a hopper mounted on elastic supports with inclined flat walls, an exciter of oscillations mounted on the hopper wall and a channel-like dispensing window, which is formed by lower areas of flat hopper walls. The flat hopper walls, between which shelves of a trough are molded, and the flat hopper walls, between which the trough walls are molded, have different slope and the dimensions of a channel-like dispensing window correspond to the dimensions of the cross section of trough. |
