A device is provided for filling granular, pulverulent and free-flowing materials into a container, preferably a hose- and sack-shaped container, made of geotextile material. The device includes a housing that allows the advancement of the material and in which a conveying device is arranged. On the entry side of the conveying device the material can be filled in and on the exit side thereof a hose made of geotextile material receives the material. The hose can be shaped on the jacket of the housing, and can be unwound as a web from a feeding device that is designed like a roll. Longitudinal sides of the web can be connected to each other by a device in the region of the jacket. The housing includes a tubular body that extends perpendicular to the direction of advance and is arranged vertically, the tubular body interacting with a feeding device for the geotextile material, which rotates about the jacket of the tubular body and is designed as an unrolling device.
