Twine Wrap Terms and Settings

E52468-UN-02JUN08

A - Twine Spacing

B - Number of Left-Hand End Wraps

C - Number of Right-Hand End Wraps

D - Left-Hand and Right-Hand End Wrap Distance

E - Re-Extension and/or Cinch Wrap Distance

There are eight factors involved in properly placing twine on the bale. The factors are:

• Twine Spacing
• Number of Left-Hand End Wraps
• Number of Right-Hand End Wraps
• Left-Hand End Wrap Distance
• Right-Hand End Wrap Distance
• Re-Extension Wrap Distance
• Cinch Wrap
• Dry Straw

The monitor-controller is programmed to apply approximate twine spacing in the center of the bale. Twine spacing decreases toward the ends of bale.

Twine Spacing (A) is the distance between twine wraps. Spacing is increased or decreased depending on how fast the twine arms move across the bale.

Mechanical twine arm spacing ranges are between 5, 10, 15, and 20 cm (2, 4, 6, and 8 in).

Monitor-controller twine spacing range is between 5—26 cm (2—10 in) at 1 cm (0.5 in) increments. Initial setting is 10 cm (4 in).

To obtain uniform twine spacing on a bale, the setting for twine arm spacing and the monitor-controller setting for twine spacing must be the same.

Number of Left-Hand End Wraps (B) and Right-Hand End Wraps (C) controls how long the twine arms pause at the end of the bale to apply the set number of end wraps for the bale diameter. End wrap setting ranges between 0.5—10 wraps. Initial setting is two wraps.

The setting for the number of end wraps is approximate for each twine arm. With various settings of the adjustable twine guide, the twine from both arms is the same distance from the end of bale. The bale has twice the number of end wraps as indicated on the monitor-controller. (See Setting Twine End Wrap Distance in this section.)

Left-Hand or Right-Hand End Wrap Distance (D) limits the twine arm travel to the outer ends of the bale. An initial setting of 10 cm (4 in) has been set for both sides. The settings can be changed in 1 cm (0.5 in) increments.

• End wrap distance settings for left and right-hand sides range between 8—26 cm (3—10 in).

End wrap distances are an approximate indication where twine is placed on the bale.

To place twine the same distance from the edge on both ends, a slightly different setting may be required for each end.

Check setting of mechanical twine guide when revising monitor-controller settings.

Re-Extension Wrap Distance (E) is a feature that may help prevent twine unrolling. It places a wrap of twine back toward middle of bale from left-hand end wrap location AFTER the set number of end wraps have been applied. Re-Extension wrap settings are 20, 40, and 60 cm (8, 16 and 24 in). (See Setting Twine Re-Extension [Advanced Operational Information] [CH 003] in this section.)

Cinch Wrap is a feature that may decrease loose twine and improve twine spacing on left-hand end of the bale. It places a wrap of twine approximately 25 cm (10 in) away from left-hand end wrap location PRIOR to applying the set number of end wraps. (See Setting Cinch Wrap [Advanced Operational Information] [Channel 004] in this section.)

Dry Straw Twine Wrap is a feature to place twine across full width of the bale to reduce straw from flaking off bale during tying. Twine arms are programmed to move to right, left, and back to right side to resume the normal tying cycle. Turn program ON or OFF. (See Using Dry Straw Twine Wrap Program [Advanced Operational Information] [Channel 002] in this section.)
