Abstract

This invention consists in a method of sealing tubular or bag-shaped packaging casings (10) filled with a tough filling, where the packaging casing (10) is first of all compressed to an adjustable degree, so that a pinched area (34) is produced, beside which a neck without filling is then produced by crimping the packaging casing (10), which neck is subsequently, if necessary, extended and sealed by setting two closure clips. The invention also consists in a sealing device comprising a crimping element (24, 26) and an additional clamping means (28, 30) for compressing the package beside the crimping element.
