6.7. Film adjustment
The quality of the silage will depend directly on the tension and position of subsequent layers of film. Optimal forage con-
ditions require the adequate squeeze and overlay of the subsequent layers of film. Before starting work, adjust the posi-
tion 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.
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 re-
quirements set out in Table 6.
