Abstract (en)
[origin: US4470783A] An apparatus for screeding and leveling coverings and coatings compounded with a binding agent, more specially a synthetic resin binding agent, is made up of a front straight edge for leveling and a back straight edge for screeding, the two straight edges being joined together as a parallelogram having a driving system for moving them backwards and forwards lengthways. As part of the apparatus there is a track-laying vehicle and a system for vertical adjustment of the straight edges.
