A method for separating portions of a food mass (3) from a film tube (1), which is continuously advanced along a tube-conveying path (9) at belt-running speed and is filled with the food mass, in particular with processed cheese (3), wherein the film tube filled with the food mass (2) is initially formed into a band of defined thickness by means of a pair of calibrating rollers, and wherein, in order to form separate food portions (3), the food mass is then displaced, by means of a pair of displacement rollers acting upon one another, out of displacement regions (2) extending transversely across the film tube, wherein the displacement rollers are driven by means of a drive, which is controllable in terms of the running thereof, in a manner decoupled from the belt-running speed.
