    摘要： An apparatus for delivering powder onto a plane surface (1) of a device for creating a three-dimensional part in a layer-by-layer fashion, in particular of a laser sintering machine, is provided. It comprises a covering means (3) which can be moved back and forth in a second direction perpendicular to said first direction by means of a drive between a lateral first position and a second position located on the opposite side. In at least one of the positions it can be filled with powder. In order to simplify the apparatus and improve its operation, the covering means (3) comprises a slit (6) extending across the entire width and open at its top and its bottom as well as smoothening elements (7, 8) at the ends opposite of the surface. A store container (9) is provided above the covering means (3), the volume of said store container at each location across the entire width being at least equal to the volume of the slit cavity located underneath.
