Adjusting Net Wrap Stretch

1. Unroll 1 m (3 ft) of material from roll of net being used. Locate a "starting" point in the net and, with net wrap pulled snug, measure between 10 weaves as shown in illustration. Divide the measurement by 10 to obtain the initial net measurement.

2. Thread net properly and make, wrap and dump a bale

NOTE: Make a uniform, cylindrical bale. (DO NOT try to measure net stretch on a "barrel shaped", lumpy, or crooked bale). Measure stretch on the bale at a point where net feels tightest.

3. Locate the end cut-off on the bale. Use the net directly under the cut-off as a "starting" point for measurement.

4. Take the measurement between 10 weaves as shown in illustration. Divide the measurement by 10 to obtain the net stretch value.

5. The net stretch value should be 3-4 mm (0.118-0.157 in.) greater than the value measured in Step 1. If measurement is not within this range, proceed to Step 6.

6. Put pressure on brake lever (D) while loosing three cap screws (C) and cap screw and washer (A).

7. Release brake lever (D).

8. Remove cap screw and washer (A). Remove sheave (B) and belt (E).

9. Separate sheave (B) by removing three cap screws (C).

NOTE: Balers are shipped from factory with two shims (G) between sheave halves.

10. Transfer shims (G) to and from stored location (F) to meet net stretch value of 3-4 mm (0.118-0.157 in.) more than the value measured in Step 1.

  • Decreasing the number of shims (G) between sheave halves will increase the distance (stretch).
  • Increasing the number of shims (G) will decrease the distance (stretch).

11. When changing shims, If necessary, readjust v-belt idler. (See CHECKING AND ADJUSTING NET WRAP V-BELT IDLER TENSION in this section).

12. When installing sheave (B), torque cap screw (A) to specification.
