Abstract: An apparatus for supporting a material bag, includes a main frame which is arranged around the material bag and includes a device for suspending the material bag. The material bag is made of a flexible material and has the shape of a block that is open at the top side and has at its four corner points of the opening a loop or an eye intended for transport or suspension in the main frame. The main frame has two substantially rectangular frames, which are pivotable with respect to one another, with one such frame having space within the other. The two substantially rectangular frames have two mutually opposing first frame parts and two mutually opposing second frame parts, of which the first frame parts are of a length that corresponds approximately to the length of the first edge of the horizontal projection of the bag and the second frame parts are of a length that is larger than the total of the second edge length of the horizontal projection of the bag and twice the loop or hook length.
