Abstract
The invention relates to a method and an apparatus for producing concrete blocks, in which concrete mortar (14) is moved across a mould (7) by means of a filling carriage (4) and the mould (7) is filled with concrete mortar (14) from the filling carriage (4), whereupon the filling carriage (4) is returned and the concrete mortar (14) located in the mould (7) is compacted first of all by means of a plunger (13), movable from above in the direction of the mould (7), and then by vibration, the plunger (13) being moved via two synchronized motors (15) located one behind the other in the direction of travel of the filling carriage (4) and the torques exerted by said motors (15) being measured, the filling operation of the mould (7) being corrected in accordance with the deviation of actual values, derived from the difference in the measured torques, from predetermined desired values.
