Template and use of a template
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.
1. A template for determining a stretching ratio of a film sample of a film spanning a round bale, the template comprising:
a template body having a supporting side and an oppositely arranged working side;
the template body including an edge defining a perimeter of the template body;
two slots formed in the template body, wherein the two slots are arranged parallel to each other and separated by a first distance;
a contact marking arranged on the working side of the template body; and
a scale, which is arranged on the working side at a predetermined distance from the contact marking, wherein the scale is configured to indicate the stretching ratio of the film sample after the film sample has been removed from the round bale and allowed to relax for a relaxation period.
2. The template set forth in claim 1 , wherein the scale includes at least one graduation mark arranged parallel to the contact marking.
3. The template set forth in claim 1 , wherein the scale is divided linearly via a plurality of graduation marks.
4. The template set forth in claim 1 , wherein the scale includes at least one graduation mark having a value associated therewith.
5. The template set forth in claim 1 , further comprising a working instruction for using the template disposed on the working side of the template body.
6. The template set forth in claim 1 , wherein the template is configured as a single piece.
7. The template set forth in claim 1 , wherein one of the slots and the contact marking lie on a straight line.
8. The template set forth in claim 1 , wherein the template body is formed from one of a paper, a plastic, or a metal.
9. A method of determining a stretch ratio of a film sample of a film spanning a round bale, the method comprising:
positioning a template onto a region of the film spanning the round bale and under tension, wherein the template includes a first slot and a second slot arranged in parallel and spaced a first distance from each other, and includes an edge defining a film sample;
marking the film through the first slot to define a first marking on the film sample;
marking the film through the second slot to define a second marking on the film sample;
severing the film sample from the film spanning the round bale, around an edge of the template body;
relaxing the film sample for a relaxation period;
positioning the film sample on the template with one of the first marking and the second marking aligned with a contact marking disposed on the template body; and
referencing the other of the first marking and the second marking to a scale disposed on the template body, whereby the scale indicates the stretch ratio.
