Adjusting the Plastic Film Stretchers
The 2 geared stretchers hold 30-inch-long (76 cm) rolls and are adjusted during assembly to
stretch the plastic film up to 65%. Generally, they require no other adjustment.
Note: If the plastic film breaks often during hot weather, detach the stretcher spring (Figure

Testing the Stretchers
To check the effectiveness of the stretchers, draw two vertical lines 10 inches apart on the
circumference of a plastic film roll with a felt-tip marker. Make the hoop turn at normal speed
for two revolutions, then measure the distance between the two lines of the bale. If you obtain
a distance of 15 or 16 inches, the stretcher is adequately stretching the plastic film. Repeat the
test for the other stretcher.
