• a first roll-shaped rotating element and a second roll-shaped rotating element which are provided parallel to and spaced apart from one another on the chassis so as to be rotatable about a respective first and second axis of rotation,
• a conveyor belt which is passed around the first and second rotating elements and forms a supporting surface for a product,
• a first filler piece which is provided between the first and second rotating elements, and a second filler piece which is fastened to the chassis between the first filler piece and the second rotating element,
• wherein the first filler piece is connected to the first rotating element in such a way that the first filler piece and the first rotating element are provided on the chassis so as to be jointly displaceable towards the second rotating element and away from the second rotating element in a direction transverse to the first axis of rotation, and
• a removable spacer element which, in use, is provided in a fitting manner between the first and second filler piece, wherein a predetermined operating distance between the first and second rotating element is determined as a result of the spacer element being placed between the first filler piece and the second filler piece.
