The invention concerns a carrier plate holding an abrading element, for detachable mounting on a rotatably mounted abrading plate driven during use, for abrading stone or concrete floors, which carrier plate has sides which form an acute angle with each other. The sides have flanges which are formed for surrounding engagement with a shoulder arranged on the abrading plate so that the carrier plate can be fixed on the abrading plate with an engagement based on form and friction.

Carrier plate holding an abrading element and abrading plate

The invention relates to an arrangement in a mobile machine for screeding floor surfaces. This comprises a housing with a planet disk (), which is rotatably supported in the bottom of the said housing and driven by a drive motor (). The planet disk carries a number of rotatably supported screeding disks, distributed over the planet disk () and operatively connected to the drive motor (). 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 (), half the number of screeding disks have a direction of rotation coinciding with the planet disk () and the remaining screeding disks an opposing direction of rotation.
