  • Patent number: 7993184
    Abstract: The invention relates to an arrangement in a mobile machine for screeding floor surfaces. This comprises a housing with a planet disk (3), which is rotatably supported in the bottom of the said housing and driven by a drive motor (1). The planet disk carries a number of rotatably supported screeding disks, distributed over the planet disk (3) and operatively connected to the drive motor (1). According to the invention the number of screeding disks is an even number up to a maximum of six. Viewed in the direction of rotation of the planet disk (3), half the number of screeding disks have a direction of rotation coinciding with the planet disk (3) and the remaining screeding disks an opposing direction of rotation.
