Abstract (en)

A knife (100) for cutting through a tube-shaped body of packaging material such that individual packages are formed. The knife (100) comprises an attachment portion (111, 112) for connecting the knife (100) to a cutting unit, such that the knife (100) is movable in a cutting direction (C), from a retracted position, to a cutting position and back to the retracted position. The knife (100) has a cutting edge (102) that extends in a direction (T) transverse to the cutting direction (C), and has a protrusion (131) which extends, as seen in the cutting direction (C), beyond the cutting edge (102) and includes an interaction surface (133) configured to interact with a sensor unit if the knife (100) is not moved to the retraced position (P1) after cutting through the tube-shaped body.
