IMPORTANT:
Uneven doffer wear WILL result when operated in extreme conditions such as tall rank plants where most cotton is doffed by top few doffers or very short plants where most cotton is doffed by few lowest doffers.
NOTE:
When unusual crop conditions cause spindle wrap, adjust doffers more often than what is considered normal for your area.
1.
In extreme conditions (tall rank plants or short plants), align spindles and adjust column height until slight drag is achieved as described in steps one through four in Adjusting Doffer Height-Normal Conditions in this section.
IMPORTANT:
The additional 1/8 turn WILL result in only a small increase of drag on spindles. At no time should the doffers actually bind against the spindles. This WILL cause spindles and bushings to be prematurely worn.
|
It is important that doffers are not set an additional 1/8 turn if it is not necessary.
2.
Tighten doffer an additional 1/8 turn to compensate for uneven doffer wear.
3.
Under extreme conditions, check and adjust doffers at least twice a day. Raise doffer off spindles and readjust.
NOTE:
In a normal crop, where doffer wear is more uniform, it is only necessary to check the doffer adjustment. In that situation, all that is required is to align a bar over the slot, and check for the drag on the spindles. In tall rank cotton or other extreme conditions with uneven doffer wear a given, the operator may still feel a drag when he checks, and just be feeling the drag on only the doffers that have not worn excessively.
