6.7. Film adjustment
The quality of the silage will depend directly on the tension and position of subsequent layers of film.
Optimal forage conditions require the adequate squeeze and overlay of the subsequent layers of film.
Before starting work, adjust the position of the film dispenser post according to film width, align the
dispenser centre with the centre of the bale (Section 6.7.3). Next, measure the film tension (Section 6.7.1)
and make adjustments if necessary (Section 6.7.2).
6.7.1 Correct film tension
The width of the film measured at the edge of the bale must be within the range shown in Table 6.
Film size [mm]
Film layer width [mm]
55% 70%
500 380 420
700 580 620
Table 6 55-70% pre-tension dimensions
The pre-tension check can be done in two ways:
The first way involves measuring the film width at the bale edge and adjusting the tension until the
desired narrowing is achieved, depending on the manufacturer's recommendations. The range of the L-
dimension must comply with the requirements set out in Table 6.
Figure 27 Tension check – method one
Method two involves drawing 2 parallel lines at a distance of 100 mm on a roll placed in the dispenser. As
a result of the film stretching, the dimension should increase. The correct distance between lines at the
55-70% film pre-tension must be between 155 and 170 mm.
