FIELD: chemical industry. SUBSTANCE: welding members form lower transverse seam 10 from bag blank 8 and, simultaneously, an incomplete upper seam 11 at one side of bag 8. Clamps 3 for gripping the blank of bag 8 have the form of a pair of strips. Filling pipe 31 with perforated housing is inserted into loading hole 33 of bag 8. Compressed air delivered into housing blows the walls of loading hole 33 from inside. Pipe 31 has a guide plate inside. As bag 8 is filled, the welding members seal loading hole 33.
