Zusammenfassung:The system has a section (10) which forms a sleeve (15) from an endless strip (13) of a thermo-weld material, a tube (20) for dispensing the liquid to be packaged, and lengthwise (16) and transverse (17) welding units. Between the end (24) of the filling tube and the transverse welding unit the system incorporates a guide (25) for the sleeve (15), made with at least one fixed wall (26,27) which is inclined relative to the vertical and designed to ensure that the liquid is injected into the pouch being formed. The guide (25) can be made with two walls (26,27) inclined relative to the vertical and which reduce the cross-section of the passage for the liquid in the direction of its flow. The angle of the two walls depends on the viscosity of the liquid being packaged, and the guide is made from sheet metal sections (26-29) linked together.
