Abstract: A device for winding up a film at a packaging machine, the device including a reception mandrel drivable for rotation about a rotation axis and a reception sleeve for the film for being pushed onto the reception mandrel. The reception sleeve may be formed by segments arranged next to each other along a circumference or perimeter of the reception sleeve, wherein neighboring or adjacent segments may be pivotably connected to each other. The reception mandrel may be formed as rigid body having engagement structures that are configured to cooperate with shape features of an inner circumference or perimeter of the reception sleeve, when the reception sleeve has been pushed onto the reception mandrel, so that a rotation of the reception mandrel about the rotation axis causes the reception sleeve to rotate with the reception mandrel.

Abstract: A tray sealer including a sealing station comprising a tool upper part, a clamping frame and a tool lower part. The tool upper part may surround a dome-shaped die used for deforming a skinnable top film. First and second channels in the dome-shaped die and in the tool upper part, respectively, are connectable to one another. The tool upper part or the dome-shaped die may comprise at least a third channel communicating with a vacuum generator so as to generate a thermal air convection from the first channel to the third channel along a side of the top film facing the dome-shaped die.
