Abstract
The invention relates to a device and a method for conveying powder. A container is provided for the powder, where the powder defines a surface in the container. A suction means has a suction opening for sucking in the powder from the surface. A moving means serves for producing a relative movement between the suction opening and the surface of the powder. During the relative movement, the powder is sucked in, a speed of the relative movement being variable in such a way that there is a constant mass flow.
