Process for production of a self-standing sack from a tube of soft plastic material containing phases of: making of two partial transverse cuts t1, t2, separated from each other; folding of the cut parts to produce a T shape; joining on the surface of traverse T of an elliptical profile E corresponding to the bottom of the sack; folding of the two parts of said traverse T and sealing of the two transverse sides to form a sack; making of two cuts along the transverse sealed edges. The machine is capable of carrying out this process. (Figure 2) <IMAGE>
