Device for leveling dry pouring material surface in floor area or floor screed by height adjustable truing tool, has cylinders and cones driven by gear drive that is arranged above level surfaces rotated at axle running through center

摘要

The device has cylinders (8) and cones or truncated cones driven by a gear drive (10) that is arranged above circular level surfaces (8a) of a height adjustable truing tool (19). The tool is fastened at an external end of a support arm (1). The support arm is pivoted at a fixed axis perpendicular to the material surface. The circular level surfaces of the tool are parallel to the material surface. The level surfaces are rotated at an axle (9) that is perpendicular to the level surfaces and runs through a level surface center.
