CANADA ABSTRACT Rags are faBricated from tubular plastics film as they are being filled. A flattened severed tube section of the bag material is clamped across its entire width at the bottom but only near the folded longitudinal edges (or the side pleats if such are provided) at the top. The walls of the tube section are pulled apart at the top between the clamped regions to present a filling aperture and welded together at the bottom across the entire width below the clamped region. After the contents of the bag have been inserted through the filling aperture, the top of the tube section is welded shut above the clamped regions and the bag is discharged.
