Abstract
Trowel device for leveling and finishing surfaces that are to be treated with masses such as concrete, characterized in that it has an eccentrically mounted rotation body formed by a preferably odd number of eccentrics mounted to rotate in the trowel device and divided into groups, the part of a group in said rotation body approximately equal to the part of the other group in said rotation body, and said eccentrics are suitable to rotate with the same speed in at least two opposite directions, so that said eccentrics move alternately passing through positions in which their component masses are summed and the forces due to the rotation of said component masses have the same direction and are applied to act in the longitudinal direction of the tools of the trowel device, and alternately move through positions in which the component masses of said eccentrics are balancing and the forces due to the rotation of said component masses cancel each other out.
