Abstract: A template for determining a stretching ratio of a film sample of a film spanning a round bale includes a template body which has a supporting side and an oppositely arranged working side. The template body includes an outline edge defining a perimeter of a film sample. Two slots are formed in the template body for applying markings to the film, the two slots being arranged parallel to each other at a first distance. A contact marking is arranged on the working side of the template body. A scale for displaying the stretching ratio of the film sample is arranged on the working side at a predetermined distance from the contact marking.

Abstract: A baler for the production of parallelepiped or slab-shaped bales is provided with a baling chamber whose cross section can be easily repositioned in height by servo motors that operate to adjust one part of the baling chamber relative to an overlapping second part. Corresponding adjustments can be made to the position of a driver for the baling piston, which itself is constructed to include separate telescoping parts. In addition, the needle assembly is provided with needle carrying arms that are mounted for movement with the movable part of the baling chamber.
